|---|---|---|---|
| 설명 | 위, 작은창자이나 큰창자에서 영양분을 흡수하기 위한 모세혈관조직은 모두 간으로 연결된다. 즉 소화기에 흡수한 영양분이 가득한 피는 모두 간으로 연결되는데 이것을 문맥계라고 한다. |

| 영문 | male reproductive system | 한글 | 남성생식기계 |
|---|---|---|---|
| 설명 | 남성의 생식기는 여러 기관으로 구성되어 있다. 고환, 부고환, 정관, 정낭, 전립샘, 외부성기(음경) 등으로 구성되는데, 실제적으로 정자를 생성하는 곳은 단 한 곳 고환뿐이며, 나머지 기관은 이를 돕는 기능을 수행하고 있다. 정자는 고환의 정세관이란 곳에서 만들어진 뒤에 밖으로 나와 긴 여정을 시작하게 된다. 그 뒤 부고환을 지나 좀 더 성숙해 진 뒤에 정관에서 정낭의 분비물과 만나고 다시 요도로 나가게 된다. 이때 요도 뒤쪽에 위치하는 전립샘의 분비물이 합쳐지게 되고 이 정액은 외부성기를 거쳐서 밖으로 나가게 된다.  |

| CANS | central auditory nervous system |
| CNS | central nervous system; clinical nurse specialist; coagulase-negative staphylococci; congenital neph... |
| CNS-L | central nervous system leukemia |

| central nervous system depressants | A very loosely defined group of drugs that tend to reduce the activity of the central nervous system. The major groups included here are ethyl alcohol, anaesthetics, hypnotics and sedatives, narcotics, and tranquillising agents (antipsychotics and antianxiety agents). (12 Dec 1998) |
|---|---|
| central nervous system infections | Diseases of the central nervous sytem collectively, caused by pathogenic organisms. (12 Dec 1998) |
| central nervous system neoplasms | Neoplasms located in the brain, spinal cord, or meninges. (12 Dec 1998) |
| central nervous system stimulants | A loosely defined group of drugs that tend to increase behavioural alertness, agitation, or excitation. They work by a variety of mechanisms, but usually not by direct excitation of neurons. The many drugs that have such actions as side effects to their main therapeutic use are not included here. (12 Dec 1998) |
| metameric nervous system | That part of the nervous system which innervates body structures developed in ontogeny from the segmentally arranged somites or, in the head region, branchial arches. The term implies reference to the neural mechanisms intrinsic to the spinal cord and brainstem (represented by the sensory nuclei, motoneuronal cell groups, and their associated interneurons in the reticular formation); by strict definition it should exclude the autonomic nervous system. (05 Mar 2000) |
| nervous system | The entire integrated system of nerve tissue in the body: the brain, brainstem, spinal cord, nerves and ganglia. (16 Dec 1997) |
| nervous system abnormalities | Congenital structural abnormalities of the nervous system. (12 Dec 1998) |
| nervous system, parasympathetic | A part of the nervous system that slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. The parasympathetic nervous system together with the sympathetic nervous system (that accelerates the heart rate, constricts blood vessels, and raises blood pressure) constitute the autonomic nervous system. (12 Dec 1998) |
| nervous system physiology | Functions and activities of the nervous system as a whole or with reference to the peripheral or the central nervous system. (12 Dec 1998) |
| nervous system, sympathetic | A part of the nervous system that accelerates the heart rate, constricts blood vessels, and raises blood pressure. The sympathetic nervous system together with the parasympathetic nervous system (that slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles) constitute the autonomic nervous system. (12 Dec 1998) |
| sympathetic nervous system | <anatomy, physiology> One of the two divisions of the vertebrate autonomic nervous system (the other being the parasympathetic nervous system). The sympathetic preganglionic neurons have their cell bodies in the thoracic and lumbar regions of the spinal cord and connect to the paravertebral chain of sympathetic ganglia. Innervate heart and blood vessels, sweat glands, viscera and the adrenal medulla. most sympathetic neurons, but not all, use noradrenaline as a post ganglionic neurotransmitter. (19 Jan 1998) |
| system, parasympathetic nervous | : A part of nervous system that slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. The parasympathetic nervous system together with the sympathetic nervous system (that accelerates the heart rate, constricts blood vessels, and raises blood pressure) constitute the autonomic nervous system. (12 Dec 1998) |
| system, sympathetic nervous | A part of nervous system that accelerates the heart rate, constricts blood vessels, and raises blood pressure. The sympathetic nervous system together with the parasympathetic nervous system (that slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles) constitute the autonomic nervous system. (12 Dec 1998) |
| involuntary nervous system | <anatomy> Neurons that are not under conscious control, comprising two antagonistic components, the sympathetic and parasympathetic nervous systems. The autonomic nervous system regulates key functions including the activity of the cardiac (heart) muscle, smooth muscles (e.g., of the gut), and glands. The autonomic nervous system has two divisions: 1. The sympathetic nervous system that accelerates the heart rate, constricts blood vessels, and raises blood pressure. 2. The parasympathetic nervous system slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. (03 Jul 1999) |
| enteric nervous system | Two ganglionated neural plexuses in the gut wall which form one of the three major divisions of the autonomic nervous system. The enteric nervous system innervates the gastrointestinal tract, the pancreas, and the gallbladder. It contains sensory neurons, interneurons, and motor neurons. Thus the circuitry can autonomously sense the tension and the chemical environment in the gut and regulate blood vessel tone, motility, secretions, and fluid transport. The system is itself governed by the central nervous system and receives both parasympathetic and sympathetic innervation. (12 Dec 1998) |
