narcotic — 1. наркотик. Medicine producing analgetic and soporific effect. The term is used mainly in respect of morphine and other medications depressing brain activity e.g. anaesthetics and substances causing the state of hypnosis in man. In judicial terminology by «narcotic» is meant the substance resulting in narcomania and, thus restricted for legal usage. Narcotics are almost replaced by soporifics for insomnia as a patient may become dependent on them. But they are still used for relieving pains. 2. Preparation for narcosis.

nephron — нефрон. Physiological unit of the kidney, that consists of renal corpuscle and tubules (length 20-50 mm). A cuplike structure — Bowman’s capsule is the beginning of the nephron. The capsule encloses a tuft of capillaries, called glomerulus, forming the renal (malpighian) corpuscle. The cavity of the Bowman’s capsule merges with the proximal part of nephron’s tubules (proximal convoluted tubule, proximal straight tubule). It’s followed by the Henle’s loop, composed of the descending (thin) segment and ascending (thick and thin (sometimes) parts). The Henle’s loop leads into the distal part of the nephron (distal straight tubule, distal convoluted tubule), followed by the collecting tubule (duct). Afferent glomerular arteriole branches into capillaries of the glomerulus, from which the urine is filtered out into the capsule’s lumen and water, nitrogenous metabolic products, and other substances (with the exception of large molecules

of proteins and formed elements of blood), comes into the re- N nal tubule, where the major part of these substances (water, electrolytes, glucose, aminoacids, small molecules of proteins) is reabsorbed into the bloodstream and the remaining fluid (urine) comes into the collecting tubules. Collecting tubules merge to

form papillary ducts (of Bellini), which terminate on the tips of the renal papilla and empty into a distended, funnel shaped part (minor calyx) of the ureter. See also fig.8.

nephrosis — нефроз. Degenerative changes of the epithelium of the renal tubules.

nerve — нерв. A bundle of nerve fibers, conveying impulses from the brain or the spinal cord to muscles and glands (motor or centrifugal nerves) or from receptors to the brain and the spinal cord (sensory or centripetal nerves). Most large nerves are mixed nerves that include centrifugal and centripetal nerves, emerging from and going to different parts of the body.

cranial nerves — черепно-мозговые нервы. Nerves emerging from the brain nuclei. There’re twelve pairs of the cranial nerves.
