CHAPTER V.
ON THE CARE OF HEALTH

There is no point, where a woman is more liable to suffer from a want of knowledge and experience, than in reference to the health of a family committed to her care. Many a young lady, who never had any charge of the sick; who never took any care of an infant; who never obtained information on these subjects from books, or from the experience of others; in short, with little or no preparation; has found herself the principal attendant in dangerous sickness, the chief nurse of a feeble infant, and the responsible guardian of the health of a whole family.

The care, the fear, the perplexity, of a woman, suddenly called to these unwonted duties, none can realize, till they themselves feel it, or till they see some young and anxious novice first attempting to meet such responsibilities. To a woman of age and experience, these duties often involve a measure of trial and difficulty, at times deemed almost insupportable; how hard, then, must they press on the heart of the young and inexperienced!

There is no really efficacious mode of preparing a woman to take a rational care of the health of a family, except by communicating that knowledge, in regard to the construction of the body, and the laws of health, which is the basis of the medical profession. Not that a woman should undertake the minute and extensive investigation requisite for a physician; but she should gain a general knowledge of first principles, as a guide to her judgement in emergencies when she can rely on no other aid. Therefore, before attempting to give any specific directions on the subject of this chapter, a short sketch of the construction of the human frame will be given, with a notice of some of the general principles, on which specific rules in regard to health are based. This description will be arranged under the general heads of Bones, Muscles, Nerves, Blood-Vessels, Organs of Digestion and Respiration, and the Skin.

BONES

The bones are the most solid parts of the body. They are designed to protect and sustain it, and also to secure voluntary motion. They are about two hundred and fifty in number, (there being sometimes a few more or less,) and are fastened together by cartilage, or gristle, a substance like the bones, but softer, and more elastic.

In order to convey a more clear and correct idea of the form, relative position, and connection, of the bones constituting the human framework, the engraving on page 70, (Fig. 1,) is given.

Fig. 1.

By the preceding engraving, it will be seen, that the cranium, or skull, consists of several distinct pieces, which are united by sutures, (or seams,) as represented by the zigzag lines; a, being the frontal bone; b, the parietal bone; c, the temporal bone; and d, the place of the occipital bone, which forms the back part of the head, and therefore is not seen in the engraving. The nasal bones, or bones of the nose, are shown at e; f, is the cheek bone; g, the upper, and h, the lower, jaw bones; i, i, the spinal column, or back bone, consisting of numerous small bones, called vertebræ; j, j, the seven true ribs, which are fastened to the spine, behind, and by the cartilages, k, k, to the sternum, or breast bone, l, in front; m, m, are the first three false ribs, which are so called, because they are not united directly to the breast bone, but by cartilages to the seventh true rib; n, n, are the lower two false, which are also called floating, ribs, because they are not connected with the breast bone, nor the other ribs, in front; o, o, p, q, are the bones of the pelvis, which is the foundation on which the spine rests; r, r, are the collar bones; s, s, the shoulder blades; t, t, the bones of the upper arm; u, u, the elbow joints, where the bones of the upper arm and fore arm are united in such a way that they can move like a hinge; v w, v w, are the bones of the fore arm; x, x, those of the wrists; y, y, those of the fingers; z, z, are the round heads of the thigh bones, where they are inserted into the sockets of the bones of the pelvis, giving motion in every direction, and forming the hip joint; a b, a b, are the thigh bones; c, c, the knee joints; d e, d e, the leg bones; f, f, the ankle joints; g, g, the bones of the foot.

The bones are composed of two substances,—one animal, and the other mineral. The animal part is a very fine network, called the cellular membrane. In this, are deposited the harder mineral substances, which are composed principally of carbonate and phosphate of lime. In very early life, the bones consist chiefly of the animal part, and are then soft and pliant. As the child advances in age, the bones grow harder, by the gradual deposition of the phosphate of lime, which is supplied by the food, and carried to the bones by the blood. In old age, the hardest material preponderates; making the bones more brittle than in earlier life.

As we shall soon have occasion to refer, particularly, to the spinal, or vertebral column, and the derangement to which it is liable, we give, on page 72, representations of the different classes of vertebræ; viz. the cervical, (from the Latin, cervix, the neck,) the dorsal, (from dorsum, the back,) and lumbar, (from lumbus, the loins.)

Fig. 2.

Fig. 2, represents one of the cervical vertebræ. Seven of these, placed one above another, constitute that part of the spine which is in the neck.

Fig. 3.

Fig. 3, is one of the dorsal vertebræ, twelve of which, form the central part of the spine.

Fig. 4.

Fig. 4, represents one of the lumbar vertebræ, (five in number,) which are immediately above the sacrum. These vertebræ are so fastened, that the spine can bend, in any direction; and the muscles of the trunk are used in holding it erect, or in varying its movements.

By the drawings here presented, it will be seen, that the vertebræ of the neck, back, and loins, differ somewhat in size and shape, although they all possess the same constituent parts; thus, A, in each, represents the body of the vertebræ; B, the articulating processes, by which each is joined to its fellow, above and below it; C, the spinous process, or that part of the vertebræ, which forms the ridge to be felt, on pressure, the whole length of the centre of the back. The back bone receives its name, spine, or spinal column, from these spinous processes.

It is the universal law of the human frame, that exercise is indispensable to the health of the several parts. Thus, if a blood-vessel be tied up, so as not to be used, it shrinks, and becomes a useless string; if a muscle be condemned to inaction, it shrinks in size, and diminishes in power; and thus it is also with the bones. Inactivity produces softness, debility, and unfitness for the functions they are designed to perform. This is one of the causes of the curvature of the spine, that common and pernicious defect in the females of America. From inactivity, the bones of the spine become soft and yielding; and then, if the person is often placed, for a length of time, in positions that throw the weight of the body unequally on certain portions of the spine, they yield to this frequent compression, and a distortion ensues. The positions taken by young persons, when learning to write or draw, or to play on the guitar, harp, or piano, and the position of the body when sleeping on one side, on high pillows, all tend to produce this effect, by throwing the weight of the body unequally, and for a length of time, on particular parts of the spine.

Fig. 5.

MUSCLES

The muscles are the chief organs of motion, and consist of collections of fine fibres or strings, united in casings of membrane or thin skin. They possess an elastic power, like India rubber, which enables them to extend and contract. The red meat in animals consists of muscles. Every muscle has connected with it nerves, veins, and arteries; and those designed to move the bones, are fastened to them by tendons at their extremities. The muscles are laid over each other, and are separated by means of membranes and layers of fat, which enable them to move easily, without interfering with each other.

The figure on page 74, represents the muscles of the arm, as they appear when the skin and fat are removed. The muscles a and b are attached, at their upper ends, to the bone of the arm, and by their lower ends to the upper part of the fore arm, near the elbow joint. When the fibres of these muscles contract, the middle part of them grows larger, and the arm is bent at the elbow. The muscle c, is, in like manner, fastened, by its upper end, to the shoulder blade and the upper part of the arm, and by its lower end to one of the bones of the fore arm, near the elbow. When the arm is bent, and we wish to straighten it, it is done by contracting this muscle. The muscles d, d, are fastened at one end near the elbow joint, and at the other near the ends of the fingers; and on the back of the hand are reduced in size, appearing like strong cords. These cords are called tendons. They are employed in straightening the fingers, when the hand is shut. These tendons are confined by the ligament or band, e, which binds them down, around the wrist, and thus enables them to act more efficiently, and secures beauty of form to the limb. The muscles at f, are those which enable us to turn the hand and arm outward. Every different motion of the arm has one muscle to produce it, and another to restore the limb to its natural position. Those muscles which bend the body are called flexors; those which straighten it, extensors. When the arm is thrown up, one set of muscles is used; to pull it down, another set: when it is thrown forward, a still different set is used; when it is thrown back, another, different from the former; when the arm turns in its socket, still another set is used; and thus every different motion of the body is made by a different set of muscles. All these muscles are compactly and skilfully arranged, so as to work with perfect ease. Among them, run the arteries, veins, and nerves, which supply each muscle with blood and nervous power, as will be hereafter described. The size and strength of the muscles depend greatly on their frequent exercise. If left inactive, they grow thin and weak, instead of giving the plumpness to the figure, designed by Nature. The delicate and feeble appearance of many American women, is chiefly owing to the little use they make of their muscles. Many a pale, puny, shad-shaped girl, would have become a plump, rosy, well-formed person, if half the exercise, afforded to her brothers in the open air, had been secured to her, during childhood and youth.

NERVES

The nerves are the organs of sensation. They enable us to see, hear, feel, taste, and smell; and also combine with the bones and muscles in producing motion.

The first engraving, on p. 77, (Fig. 6,) is a vertical section of the skull, and of the spinal column, or back bone, which supports the head, and through which runs the spinal cord, whence most of the nerves originate. It is a side view, and represents the head and spine, as they would appear, if they were cut through the middle, from front to back. Fig. 7, exhibits them as they would appear, if viewed from behind. In Fig. 6, a, represents the cerebrum, or great brain; b, the cerebellum, or little brain, which is situated directly under the great brain, at the back and lower part of the head; c, d, e, is the spinal marrow, which is connected with the brain at c, and runs through the whole length of the spinal column. This column consists, as has already been stated, of a large number of small bones, f, f, called vertebræ, laid one above another, and fastened together by cartilage, or gristle, g, between them.

Fig. 6.

Fig. 7.

Between each two vertebræ, or spinal bones, there issues from the spine, on each side, a pair of nerves. The lower broad part of the spine, (see p, Fig. 1, p. 70, and Fig. 7, p. 77,) is called the sacrum; in this, are eight holes, through which the lower pairs of nerves pass off.

The nerves of the head and lungs run directly from the brain; those of all other parts of the body proceed from the spine, passing out in the manner already mentioned.

The nerves which thus proceed from the spine, branch out, like the limbs and twigs of a tree, till they extend over the whole body; and, so minutely are they divided and arranged, that a point, destitute of a nerve, cannot be found on the skin.

Some idea of the ramifications of the nerves, may be obtained by reference to the following engraving, (Fig. 8.) In this, A, A, represents the cerebrum, or great brain; B, B, the cerebellum, or little brain; (see also a, b, in Fig. 6;) C, C, represents the union of the fibres of the cerebrum; D, D, the union of the two sides of the cerebellum; E, E, E, the spinal marrow, which passes through the centre of the spine, (as seen at c, d, e, in Fig. 6;) 1, 2, 3, 4, 5, 6, branches of the nerves going to different parts of the body. As the nerves are the organs of sensation, all pain is an affection of some portion of the nerves. The health of the nerves depends very greatly on the exercise of the muscles, with which they are so intimately connected. This shows the reason why the headache, tic douloureux, diseases of the spine, and other nervous affections, are so common among American women. Their inactive habits, engender a debility of the nervous system, and these diseases follow, as the consequence.

Fig. 8.

It can be seen, by a reference to the side view, represented on page 77, (Fig. 6,) that the spine is naturally curved back and forward. When, from want of exercise, its bones are softened, and the muscles weakened, the spine acquires an improper curve, and the person becomes what is called crooked, having the neck projected forward, and, in some cases, having the back convex, where it should be concave. Probably one half of the American women have the head thus projecting forward, instead of carrying it in the natural, erect position, which is both graceful and dignified.

The curvature of the spine, spoken of in this work as so common, and as the cause of so many diseases among American women, is what is denominated the lateral curvature, and is much more dangerous than the other distortion. The indications of this evil, are, the projection of one shoulder blade more than the other, and, in bad cases, one shoulder being higher, and the hip on the opposite side more projecting, than the other. In this case, the spine, when viewed from behind, instead of running in a straight line, (as in Fig. 7 and 9,) is curved somewhat, as may be seen in Figures 10 and 11.

This effect is occasioned by the softness of the bones, induced by want of exercise, together with tight dressing, which tends to weaken the muscles that are thus thrown out of use. Improper and long continued positions in drawing, writing, and sleeping, which throw the weight of the body on one part of the spine, induce the same evil. This distortion is usually accompanied with some consequent disease of the nervous system, or some disarrangement of the internal organs.

By comparing Figures 9 and 11, the difference between a natural and distorted spine will be readily perceived. In Fig. 10, the curved line shows the course of the spine, occasioned by distortion; the perpendicular line, in this and Fig. 11, indicates the true direction of the spine; the horizontal lines show that one shoulder and hip are forced from their proper level.
