This phenomenon, which we call dilatation of the womb, is brought about by involuntary contractions of the muscle fibers in its wall, every point of which they draw upward. Now, the top of the womb is directly opposite its mouth, consequently the contractions inevitably pull its lips wider and wider apart. Ordinarily another factor is concerned in this mechanism.
Because of the relationship between the long axes of the femur and iliac shaft it is evident that the angle formed by these two bones is maintained chiefly by the gluteus muscles during weight bearing. Contraction of muscular fibers of the gluteus medius causes extension of the femur and muscular strain is prevented to a great degree by the inelastic portion of this muscle.
The Venetian red of her hair trapped the reflected sunlight from the opposite windows, and two little points of silver danced in her blue eyes. Ah! but her eyes were blue; blue as spring-water in the morning, blue as the summer sky seen through a cleft in the mountains, blue as lapis-lazuli, with the same fibers of gold.
The fibers would all be alike. You have named seven people to me, including myself, as possibly guilty of these these murders. Your conclusions may be very unjust and may lead to a serious miscarriage of justice." Kennedy was unperturbed.
They come of lusts which obsess the interiors of the mind, from these flow into the body, and excite uncleannesses there which titillate the fibers. The physical pleasure springs from the pleasure which the mind takes in lusts.
C. Section of a nerve trunk. 1. Epineurium consisting chiefly of connective tissue. 2. Bundles of nerve fibers. 3. Covering of fiber bundle, or perineurium. 4. Small artery and vein. The side-by-side arrangement of the neurons shows clearly the structure of the ganglia and nerves.
One set of nerves causes contraction of the muscular fibers of the uterus, while the other set transmits impulses which bring about its vascular engorgement; and they are probably concerned in bringing about the determination of blood to the uterus and its appendages, which is so marked a feature of the menstrual process.
When the attack subsides, the iris falls away from the cornea. Aside from the congestion, the primary changes that take place in the iris are indicative of paresis of the fibers of the motor oculi that supply the sphincter pupillae, and stimulation of the fibers from the sympathetic producing vasomotor spasm.
They are dependent upon the modificability of nerve cells and fibers by stimuli, e. g., a light flashing through the pupil and passing along the optical tracts to the occipital cortex produces changes which constitute the basis of visual memory. Experience modifies nervous tissue in definite manner, and SOMETHING remembers. Who remembers? Who is conscious?
In the cerebrum they extend in three general directions, forming three classes of fibers. The second make connection between the two hemispheres, and form the corpus callosum. In the cerebellum both association and commissural fibers are found. Bands of fibers, passing upward toward the cerebrum and downward toward the cord, connect this part of the brain with other parts of the nervous system.
