Physiology and Hygiene for Secondary Schools This is a long, rod-like mass of white nerve fibers, surrounding a central mass of gray matter. A Practical Physiology But his work had reference to the growth of tissues only of coldblooded animals, he having cultivated artificially, nerve fibers from the central nervous system of the frog. The Great Events by Famous Historians, Volume 21 The Recent Days (1910-1914) Furthermore, they found that nitella fibers, on being excited, propagate electrical waves that are similar in every way, except velocity, to those of the nerve fibers in animals and man. Autobiography of a Yogi The nervous current thus generated is conducted over long nerve fibers, through the spinal cord to the brain where it is received and we experience a sensation. How to Use Your Mind A Psychology of Study: Being a Manual for the Use of Students and Teachers in the Administration of Supervised Study These contain the great bundles of nerve fibers that connect the cerebrum with the parts of the nervous system below.

A Practical Physiology Last is a layer of fine nerve fibers, g, and gray, ganglionic cells, h, like the gray matter of the brain, whence filaments extend into i, the fibers of the optic nerve. Hygienic Physiology : with Special Reference to the Use of Alcoholic Drinks and Narcotics Until now no satisfactory method had been found to study the passages of the impulses along the nerve fibers in living animals or man because of the great speed with which these impulses travel. Autobiography of a Yogi In the disease, it seemed, the nerve fibers themselves in the small nerves broke down and the affection was motor, sensory, vasomotor, or endemic. The Treasure-Train Through the branching of the nerve fibers many pathways are open to the impulses. Physiology and Hygiene for Secondary Schools Now these nerve fibers terminate in a peculiar way in those parts of the body which are endowed with a very delicate sense of touch.

A Practical Physiology In a general way, the nerve fibers resemble an electric cable wire with its central rod of copper, and its outer non-conducting layer of silk or gutta percha. A Practical Physiology Like the copper rod, the axis cylinder along which the nerve impulse travels is the essential part of a nerve fiber. A Practical Physiology Thus the nerve cells and nerve fibers are related, in that the process of one is the axis cylinder and essential part of the other. A Practical Physiology The axon, or nerve fiber, is a long, slender extension from the cell-body, which connects with some organ or tissue. Physiology and Hygiene for Secondary Schools The sweat glands are under the control of certain nerve fibers originating in the spinal cord, and are not necessarily excited to action by an increased flow of blood through the skin. A Practical Physiology The whole nerve, not unlike a minute tendon in appearance, is covered by a dense sheath of fibrous tissue, in which the blood-vessels and lymphatics are distributed to the nerve fibers. A Practical Physiology The nerve fibers, on the other hand, are conductors of nervous energy. A Practical Physiology Two nerve fibers, showing the nodes or constrictions of Ranvier and the axis cylinder. A Practical Physiology Structure of the Axon.—The axon, or nerve fiber, has practically the same structure in both classes of neurons, being composed in most cases of three distinct parts. Physiology and Hygiene for Secondary Schools However complicated the structure of nerve tissue in man seems to be, it is found to consist of only two different elements, nerve cells and nerve fibers. A Practical Physiology The brain is the main office, and the multitudes of nerve fibers branching off to all parts of the body are the wires. A Practical Physiology The brain is the largest and most complex mass of nerve tissue in the body, made up of an enormous collection of gray cells and nerve fibers. A Practical Physiology The ganglia of the sympathetic system are connected with each other and with the sensory roots of the spinal nerves by a network of gray nerve fibers. A Practical Physiology |
