| 영문 | cerebral concussion | 한글 | 뇌진탕 |
|---|---|---|---|
| 설명 | 외부에서 기원하는 물리적 충격으로 인해 뇌의 물리적 손상없이 일어나는 뇌의 기능 장애. 일시적으로 무의식, 반사소실, 등이 나타나지만 결국은 아무 후유증없이 정상으로 돌아온다. |

| 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. |

|---|---|
| anterior cerebral artery | <anatomy, artery> One of the two terminal branches (with middle cerebral artery) of the internal carotid; it passes anterior, loops around the genu of the corpus callosum then posteriorly in the interhemispheric fissure along with its fellow of the opposite side, the two being joined by the anterior communicating artery; for descriptive purposes it is divided into two parts: the precommunical part (A2 segment of clinical terminology), supplying branches to the thalamus and corpus striatum, and the postcommunical part, (A2) or pericallosal artery, supplying branches to the cortex of the medial parts of the frontal and parietal lobes. Synonym: arteria cerebri anterior. (05 Mar 2000) |
| plexus of anterior cerebral artery | <anatomy, artery> An autonomic plexus accompanying the anterior cerebral artery, derived from the internal carotid plexus. Synonym: plexus arteriae cerebri anterioris. (05 Mar 2000) |
| posterior cerebral artery | <anatomy, artery> Formed by the bifurcation of the basilar artery; it passes around the cerebral peduncle to reach the medial aspect of the hemisphere; for descriptive purposes it is divided into three parts: 1) the precommunical part (P1 segment of clinical terminology), the part before the junction with the posterior communicating artery, supplying parts of the thalamus, hypothalamus, and midbrain; 2) the postcommunical part (P2), supplying the thalamus, cerebral peduncles, and the choroid plexuses of the lateral and third ventricles; and 3) the terminal or cortical part, supplying the cortex of the temporal (P3) and occipital (P4) lobes. Synonym: arteria cerebri posterior. (05 Mar 2000) |
| body of sphenoid bone | The central portion of the sphenoid bone from which the greater and lesser wings and the pterygoid processes arise. The sphenoidal sinuses lie within it. Synonym: corpus ossis sphenoidalis. (05 Mar 2000) |
| vaginal process of sphenoid bone | A thin lamina of bone that extends medially under the body of the sphenoid bone from the medial lamina of the pterygoid process; it articulates with the vomer and the palatine bone. Synonym: processus vaginalis ossis sphenoidalis, sheath process of sphenoid bone. (05 Mar 2000) |
| parietal border of sphenoid bone | The margin of the greater wing of the sphenoid that articulates with the parietal bone. Synonym: margo parietalis ossis sphenoidalis. (05 Mar 2000) |
| greater wing of sphenoid bone | Strong squamous processes extending in a broad superolateral curve from the body of the sphenoid bone. The greater wing presents these suraces (facies): 1) cerebral surface: forms anterior third of the floor of the lateral portions of the middle cranial fossa; 2) temporal surface: forms the deepest portion of the temporal fossa; 3) infratemporal surface, forms the "roof" of the infratemporal fossa; 4) orbital surface: forms posterolateral wall of orbit. The greater wing forms the inferior border of the supraorbital fissure, and is perforated at its root by foramina rotundum ovale, and spinosum and the pterygoid canal. Synonym: ala major ossis sphenoidalis, ala temporalis. (05 Mar 2000) |
| rostrum of the sphenoid bone | The anterior projecting part of the body of the sphenoid bone which articulates with the vomer. Synonym: rostrum sphenoidale. (05 Mar 2000) |
| hamular process of sphenoid bone | The inferior, hook-shaped extremity of the medial plate of the pterygoid process. Synonym: hamulus pterygoideus, hamular process of sphenoid bone. (05 Mar 2000) |
| scaphoid fossa of sphenoid bone | A boat-shaped hollow. A longitudinal hollow on the posterior surface of the superior portion (root) of the medial pterygoid plate; it gives origin to the tensor veli palati muscle. Synonym: fossa scaphoidea ossis sphenoidalis, Cruveilhier's fossa, fossa navicularis Cruveilhier, scaphoid fossa of sphenoid bone. Synonym: scapha. (05 Mar 2000) |
| pterygoid ridge of sphenoid bone | A rough ridge marking the angle of union of the temporal and infratemporal surfaces of the greater wing of the sphenoid bone. Synonym: crista infratemporalis, pterygoid ridge of sphenoid bone. (05 Mar 2000) |
| sheath process of sphenoid bone | A thin lamina of bone that extends medially under the body of the sphenoid bone from the medial lamina of the pterygoid process; it articulates with the vomer and the palatine bone. Synonym: processus vaginalis ossis sphenoidalis, sheath process of sphenoid bone. (05 Mar 2000) |
| sphenoid | 1. Wedge-shaped; as, a sphenoid crystal. 2. <anatomy> Of or pertaining to the sphenoid bone. <anatomy> Sphenoid bone, an irregularly shaped bone in front of the occipital in the base of the skull of the higher vertebrates. It is composed of several foetal bones which become united the adult. See Alisphenoid, Basisphenoid, Orbitosphenoid, Presphenoid. Origin: Gr.; a wedge + form: cf. F. Sphenoide. 1. <chemistry> A wedge-shaped crystal bounded by four equal isosceles triangles. It is the hemihedral form of a square pyramid. 2. <anatomy> The sphenoid bone.

| sphenoid bone | A bone of most irregular shape occupying the base of the skull; it is described as consisting of a central portion, or body, and six processes: two greater wings, two lesser wings and two pterygoid processes; it articulates with the occipital, frontal, ethmoid, and vomer, and with the paired temporal, parietal, zygomatic, palatine and sphenoidal concha bones. Synonym: os sphenoidale, sphenoid. (05 Mar 2000) |
