| 설명 | 뇌막은 크게 3종류의 막으로 구성되어 있으며, 제일 바깥막은 뼈을 싸고 있는 막과도 연결되는 경질막(dura mater)이고, 그 다음 거미막(arachnoid membrane), 그리고 유막(pia mater)으로 구성되어 있다. 이중 거미막과 유막을 합쳐서 연수막(leptomeninges)이라고 부르고, 맨위 경질막을 경질막(pachymeninx)이라 부른다. 경질막의 밑공간을 겉질막밑공간이라 부르는데, 여기에는 많은 혈관이 지나간다. 또한 거미막의 밑공간을 거미막밑공간이라 부르는데 여기에 뇌척수액이 차있다. 유막(pia mater)의 밑에는 바로 뇌조직이 존재하며, 이를 통해 뇌조직으로 가는 피가 들어가게 된다(뇌혈관 장벽=BBB: blood brain barrier: 뇌조직과 피사이에는 바로 교통이 되는 것이 아니고 이런 장벽을 통해서만 영양분이 뇌조직으로 교환될 수 있다). |

| meninges | <anatomy> The surrounding membranes the brain and spinal cord. There are three layers: the dura mater (outer), arachnoid membrane (middle) and the pia mater (inner layer). (27 Sep 1997) |
|---|---|
| primitive | Undeveloped or in early stages of development, undifferentiated. (16 Dec 1997) |
| primitive aorta | The paired aortic primordia in young embryos. (05 Mar 2000) |
| primitive chorion | The chorion before its villi are well formed. Synonym: previllous chorion. (05 Mar 2000) |
| primitive costal arches | Arch's formed in the thoracic region of the vertebral column in the embryo from the costal processes or costal elements which give rise to the ribs. (05 Mar 2000) |
| primitive erythroblast | <cell biology> Large cell with euchromatic nucleus found in mammalian embryos. In the mouse, the cells are located in the yolk sac and are responsible for early production of erythrocytes with foetal haemoglobin. (18 Nov 1997) |
| primitive furrow | The median depression in the primitive streak flanked by the primitive ridges. Synonym: primitive furrow. (05 Mar 2000) |
| primitive groove | The median depression in the primitive streak flanked by the primitive ridges. Synonym: primitive furrow. (05 Mar 2000) |
| primitive gut | A flat sheet of intraembryonic endoderm that will change into a tubular gut due to the folding of embryonic body-head, tail and lateral body folds. Synonym: archenteron, celenteron, endodermal canal, subgerminal cavity. (05 Mar 2000) |
| primitive knot | A local thickening of the blastoderm at the cephalic end of the primitive streak of the embryo. Synonym: Hensen's knot, Hensen's node, Hubrecht's protochordal knot, primitive knot, protochordal knot. (05 Mar 2000) |
| primitive meninx | The embryonic loose mesenchymatous tissue surrounding the brain and spinal cord; from it the three definite meninges (arachnoidea, dura mater, and pia mater) are derived. Synonym: meninx primitiva. Meninx serosa, obsolete term for arachnoidea; the arachnoid is actually not a serous membrane. (05 Mar 2000) |
| primitive neuroectodermal tumour | A designation used to refer to a group of morphologically similar embryonal neoplasms that arise in intracranial and peripheral sites of the nervous system and which may show various degrees of cellular differentiation; includes medulloblastoma, pineoblastoma, etc. (05 Mar 2000) |
| primitive neuroectodermal tumours | A type of brain tumour. Prenatal diagnosis: diagnosis before birth. Methods for prenatal diagnosis include ultrasound (of the uterus, placenta and developing foetus), chorionic villus sampling to obtain tissue for chromosome or biochemical analysis, amniocentesis to obtain amniotic fluid for the analysis of chromosmes, enzymes, DNA, etc. A growing number of birth defects and diseases are now amenable to prenatal diagnosis. Also called antenatal diagnosis. (12 Dec 1998) |
| primitive node | A local thickening of the blastoderm at the cephalic end of the primitive streak of the embryo. Synonym: Hensen's knot, Hensen's node, Hubrecht's protochordal knot, primitive knot, protochordal knot. (05 Mar 2000) |
| primitive palate | In the early embryo, the mesoderm-filled shelf, formed from the medial nasal process, that anteriorly separates the oral cavity below from the primitive nasal cavities above. Synonym: primitive palate. (05 Mar 2000) |
