| 영문 | cerebral cortex | 한글 | 대뇌겉질 |
|---|---|---|---|
| 설명 | 대뇌의 표면부위를 대뇌겉질이라고도 한다. 대개 얕은회색질(superficial gray matter)와 동의어로 쓰인다. 회색질이란 대뇌의 표면에 신경세포가 모여있는 곳으로 회색을 띠는 부분을 말한다. 이와는 대조적으로 백색질이란 신경세포가 내는 신경섬유가 분포하는 곳이며 대뇌에서 회색질의 안쪽에 존재한다. 참고로 말하면 척수에서는 대뇌와 반대로 회색질 안쪽에 존재하고 백색질이 밖에 존재한다. 즉 척수에서는 신경세포가 척수의 안쪽에 존재하고 바깥쪽에 그 신경세포가 내는 신경섬유가 존재한다. |

| 영문 | cerebral artery | 한글 | 대뇌동맥 |
|---|---|---|---|
| 설명 | 대뇌의 혈액을 공급하는 동맥. 대뇌의 앞부분의 혈액을 공급하는 앞대뇌동맥(anterior cerebral artery), 중간부위의 혈액을 공급하는 중간대뇌동맥(middle cerebral artery), 뒷부분의 혈액을 공급하는 뒤대뇌동맥(posterior cererbral artery)의 세 가지가 있다. 대뇌는 크게 두 가지 동맥에 의해서 혈액을 공급받는다. 하나는 속목동맥(internal carotid artery)이고 하나는 척추동맥(vertebral artery)이다. 이 동맥들은 좌-우로 두 개씩 쌍을 이루어 뇌에 혈액을 공급한다. 척추동맥은 대동맥에서 나와서 목뼈에 있는 가로돌기구멍을 통해서 머리쪽으로 올라온다. 그리고는 두 개의 좌우 척추가 한 개로 합쳐져서 바닥동맥라는 동맥을 이룬다. 목동맥은 대동맥에서 기시하여 속목동맥과 바깥목동맥으로 나뉜다(나뉘기 이전을 온목동맥이라 한다). 바깥목동맥은 얼굴과 뇌를 제외한 머리의 부위에 혈액을 공급하는 혈관이고, 속목동맥은 뇌에 혈액을 공급한다.   |

| 설명 | 대뇌란 뇌의 가장 큰 부분을 차지하는 곳으로 사고, 운동, 성격, 기억 등의 고차원적인 기능을 행하는 곳이다. 대뇌는 크게 좌, 우 두 개로 나뉘어져 있고 각각을 좌, 우 대뇌반구라고 한다. |

| middle cerebellar peduncle | The largest of three paired cerebellar peduncles, composed mainly of fibres that originate in the pontine nuclei, cross the midline in the ventral part of pons, and emerge on the opposite side as a massive bundle arching dorsally along the lateral side of the pontine tegmentum into the cerebellum; its fibres are distributed chiefly to the cortex of the cerebellar hemisphere. Synonym: pedunculus cerebellaris medius, brachium pontis. (05 Mar 2000) |
|---|---|
| superior cerebellar peduncle | A large bundle of nerve fibres that originate from the dentate and interpositus nuclei and emerges from the cerebellum in the rostral direction, along the lateral wall of the fourth ventricle. The bundle submerges from the dorsal surface of the brainstem into the mesencephalic tegmentum, where all of its fibres cross in the massive decussation of the superior cerebellar peduncles. Part of the bundle terminates in the contralateral red nucleus; the bulk of the fibres continue rostrally to parts of the ventral intermediate nucleus of thalamus, ventral posterolateral nucleus of thalamus, and central lateral nucleus of thalamus. Synonym: pedunculus cerebellaris superior, brachium conjunctivum cerebelli. (05 Mar 2000) |
| inferior cerebellar peduncle | Large paired bundles of nerve fibres which develop on the dorsolateral surfaces of the upper medulla, extend under the lateral recesses of the rhomboid fossa and curve dorsally into the cerebellum medial to the middle cerebellar peduncle; composed of a larger (lateral) bundle, the restiform body, and a small (medial) bundle, the juxtarestiform body. Fibres forming this composite bundle originate from spinal neurons and medullary relay nuclei. The largest constituent (restiform body) is crossed fibres from the inferior olive; it also contains the dorsal spinocerebellar tract and cerebellar projections from the lateral reticular nucleus, the accessory cuneate nucleus, the paramedian reticular nuclei and the perihypoglossal nuclei. Vestibulocerebellar fibres are placed medially in the inferior cerebellar peduncle and are usually separately identified as the juxtarestiform body. Synonym: pedunculus cerebellaris inferior. (05 Mar 2000) |
| inferior thalamic peduncle | A large fibre bundle emerging from the anterior part of the thalamus in the ventral direction, in part joining the medial fibres of the internal capsule, in other part curving laterally around the medial margin of the capsule into the innominate substance. Many of its fibres establish a reciprocal connection of the mediodorsal nucleus of the thalamus with the orbital gyri of the frontal lobe, but numerous other fibres constitute a conduction system from the amygdala and olfactory cortex to the mediodorsal nucleus. See: ansa peduncularis. Synonym: pedunculus thalami inferior. (05 Mar 2000) |
| olfactory peduncle | A nervelike, white band composed primarily of nerve fibres originating from the mitral cells and tufted cells of the olfactory bulb but also containing the scattered cells of the anterior olfactory nucleus. The tract is closely applied to the ventral surface of the frontal lobe, and attaches itself to the base of the cerebral hemisphere at the olfactory trigone, beyond which it extends in the form of the olfactory striae which distribute their fibres to the olfactory tubercle and, in largest number, to the olfactory cortex on and around the uncus of the parahippocampal gyrus. See: olfactory nerves. Synonym: tractus olfactorius, olfactory peduncle. (05 Mar 2000) |
| lateral thalamic peduncle | The massive group of fibres that emerges from the laterodorsal side of the thalamus to join the corona radiata; it reciprocally connects the lateral nucleus and the geniculate bodies of the thalamus with the corresponding regions of the cerebral cortex. Synonym: pedunculus thalami lateralis. (05 Mar 2000) |
| ventral | 1. Pertaining to the belly or to any venter. 2. Denoting a position more toward the belly surface than some other object of reference, same as anterior in human anatomy. Origin: L. Ventralis (18 Nov 1997) |
| ventral anterior nucleus of thalamus | The most rostral of the subdivisions of the ventral nucleus, receiving projections from the globus pallidus and projecting to the premotor and frontal cortex. Synonym: nucleus ventralis anterior thalami. (05 Mar 2000) |
| ventral aortas | The paired vessels ventral to the pharynx, which give rise to the aortic arches. (05 Mar 2000) |
| ventral border | The ventral or most forward margin of a structure. Synonym: anterior margin, ventral border. (05 Mar 2000) |
| ventral branch | Rami ventralis See: ventral primary rami of cervical spinal nerves, ventral primary rami of lumbar spinal nerves, ventral primary rami of sacral spinal nerves, ventral primary ramus of spinal nerve. (05 Mar 2000) |
| ventral decubitus | Pressure sores (decubitus ulceration) occurring in ventral locations, such as the abdominal wall or the anterior surface of an extremity. (05 Mar 2000) |
| ventral glands | <entomology> Insect structures that originate from the ectoderm of the ventrocaudal part of the head and serve as a source of ecdysone. Synonym: peritracheal glands, prothoracic glands, thoracic glands, ventral glands. (05 Mar 2000) |
| ventral hernia | An abdominal incisional hernia. (05 Mar 2000) |
| ventral horn | The anterior or frontal division of the lateral ventricle of the brain, extending forward from Monro's interventricular foramen. See: lateral ventricle. (05 Mar 2000) |
