SYSTEM

and all organs containing involuntary muscle. The autonomic system includes all of the sympathetic nervous system (called sympathetic autonomic) and fibers of the Vagus nerve (called iagul autonomic). The action of the vagal autonomic is the opposite of that of the sympathetic, and the vagal autonomic is, therefore, known as the an fag on is tic system. Bertillon s., a system of identification based on various measurements of the body. color of the eyes, etc. blood-vascular s., the blood-ve els collectively. Borstal s.,a system of treating criminals, especially juvenile ones, by removing them from evil environment and placing them under wholesome influences. case 8., a system of teaching based on the logical analysis of and deductions formed from, reported cases. central nervous s., the brain and spinal cord. cerebellorubral s., a system of motor-tibers joining the dentate nucleus of the cerebellum with the red nucleus of the opposite side. cerebellorubrospinal s., the cerebellorubral and rubrospinal systems considered together. cerebrospinal s., the brain, spinal cord. and their branches. circulatory s., the blood and lymph ve els and organs together; the vascular system. dentinal s., all the tubules radiating from a single pulp-cavity. dermal s., dermoid s., the skin and its appendages, including both the hair and the nails. digestive 8., the entire gastro-intestinal tract with its a ociated organs and_ glands. dosimetric s., a regular and determinate system of dosage. endocrine s., the system of glands which elaborate internal secretions, including the thymus, thyroid, adrenals, pituitary, testicles, ovaries, etc. est hes iodic s., the sensory apparatus of the spinal cord. glandular s., the glandular structures of the body considered together. havers i an s., a set of canaliculi connected with each havers i an canal; also the canaliculi of a bone collectively considered. hematopoietic s., the blood-making system, the spleen and bone-marrow. heterogeneous s., any system or structure made up of mechanically separable parts, as an emulsion. homogeneous 8., a system or structure the parts of which cannot be mechanically separate, as a solution. intermediary s., the bony ti ue in the spaces between the havers i an system. kinesodic 8., the motor elements of the spinal cord. Kinetic s., Crile’s term for the system of organs through which latent energy is converted into heat and motion: these organs are the brain, thyroid, liver. adrenals, pancreas, and the muscles. lymphatic 8., a collective name for the lymphatic glands, ve els, sinuses, and spaces, the lacteals, and the serous membranes. muscular 8., all the muscles of the body considcred together. nervous 5., all the nerves and nerve-centers, nervous ti ues, and ganglia considered together. pedal s., the pyramidal tract, or caudate nucleus, and the anterior and posterior caudate hbers. Pinel’s s8., management of the insane without the use of forcible restraint. portal s., the capillaries of the liver which convey venous blood from the portal vein into the hepatic vein. projection s., the system of tracts of nerve-fibers in the brain by means of which external objects are brought into consciousne . rubrospinal s., the red nucleus together with Monakow’s bundle, by which the former is connected with the opposite side of the spinal cord. sympathetic nervous s., the chain of nerve ganglia extending on each side of the spinal column, connected with each other and connected also with the spinal nerves. The sympathetic system supplies the involuntary muscles and has an intimate tel at i on with vasomotion, secretion, and various trophic proce es. The sympathetic system is also known as the visceral or vegetative nervous system because the organs controlled by it functionate unconsciously. The sympathetic system shows an independence of action of the central nervous system and forms one of the autonomic systems, and is thus spoken of as the sympathetic autonomic system as contrasted with the vagal autonomic system. Cf. autonomic nervous system. urogenital s., the organs of generation together with the kidneys, ureters, and bladder: uropoietic s., the kidneys, ureters, bladder, and urethra. vascular s., the system of ve els of the body, especially the blood-ve els of the body. systematic (sis-tem-at’ik) (Gr. συστηματικός].

The term systole especially designates the contraction of the ventricles as distinguished from that of the auricles. It occurs synchronously with the first heart sound, and by it the blood is driven into the aorta and pulmonary artery. aborted s., a systole not appreciable through the pulse on account of mitral regurgitation. 8. alter’ans, hem i systole. Made systematic tic arra ts. 961 TABLE _ anticipated s., a ventricular systole which occurs before the ventricle is filled. arte: s., the rhythmic contraction of an artery. auric- 8., the contraction of the auricles by which the blood is forced from them into the ventricles: it precedes the true or ventricular systole. catalectic s., an aborted or imperfect systole. extra-s., a premature contraction of an auricle or ventricle, or of both, while the fundamental rhythm is maintained at the sinus. ventricular 8., the contraction of the ventricles of the heart by which the blood is forced into the aorta and pulmonary artery.
