| 영문 | pancreatic duct | 한글 | 이자관, 췌장관 |
|---|---|---|---|
| 설명 | 이자에서 이자액을 분비하도록 샘창자로 이어진 관. 이자관은 샘창자의 중간부에서 온쓸개관과 같이 개구한다. |

| 영문 | nasolacrimal duct | 한글 | 코눈물관 |
|---|---|---|---|
| 설명 | 눈물은 대개 눈물샘에서 만들어져 눈을 적신 뒤에 누관을 거쳐서 눈물주머니에 모인 뒤에 이 코눈물관으로 흘러 코 안쪽으로 내려가게 된다. 만일 여기가 막히면, 눈물이 계속 고이게 되어 계속 눈물을 흘리게 되며, 또한 병균의 서식처가 되어 감염의 위험성이 높아진다. |

| 영문 | plasma membrane | 한글 | 형질막 |
|---|---|---|---|
| 설명 | 원형질 표면을 덮는 엷은막. 두께는 5~25μm이다. 광학현미경으로는 관찰할 수 없지만 전자현미경으로 관찰이 가능하다. 원형질막의 분자구조는 레시틴이나 콜레스테롤 등의 표면 활성물질 분자가 2분자층으로 그 표면에 배열되며, 이것을 각 1분자층의 단백질 분자가 양쪽에서 샌드위치한 단위막 구조이다. 전자현미경적으로 이 단위는 암-명-암의 3층(각 약 20nm)으로 구별된다. 원형질의 투과성에 중요한 구실을 하며, 생리상태가 변하면 그 투과성도 신속히 변한다. 또, 손상이 되면 쉽게 새로 형성된다. |

| basilar cartilage | The cartilage filling the foramen lacerum. Synonym: basilar fibrocartilage, fibrocartilago basalis. (05 Mar 2000) |
|---|---|
| basilar cell | <pathology> General term for relatively undifferentiated cells in an epithelial sheet that give rise to more specialised cells act as stem cells). In the stratified squamous epithelium of mammalian skin the basal cells of the epidermis (stratum basale) give rise by an unequal division to another basal cell and to cells that progress through the spinous, granular and horny layers, becoming progressively more keratinised, the outermost being shed as squames. In olfactory mucosa the basal cells give rise to olfactory and sustentacular cells. In the epithelium of epididymis their function is unclear, but they probably serve as stem cells. (13 Nov 1997) |
| basilar fibrocartilage | The cartilage filling the foramen lacerum. Synonym: basilar fibrocartilage, fibrocartilago basalis. (05 Mar 2000) |
| basilar impression | An invagination of the base of the skull into the posterior fossa with compression of the brainstem and cerebellar structures into the foramen magnum. Compare: platybasia. (05 Mar 2000) |
| basilar index | Ratio between the basialveolar line and the maximum length of the cranium, according to the formula: (basialveolar line × 100)/length of cranium. Synonym: alveolar index. (05 Mar 2000) |
| basilar interstitial lung disease | <radiology> B bronchiectasis, A asbestosis, D drugs / DIP, L lymphangitic metastasis / LAM, A aspiration, S sarcoidosis, S scleroderma (12 Dec 1998) |
| basilar invagination | <radiology> Dens projects into base of skull, McGregor's line greater than 4.5 mm, Chamberlain's line greater than 3 mm, may lead to obstructive hydrocephalus aetiology: primary anomalies of occiput, atlas, axis, softened bone: rickets / osteomalacia, Paget's disease, fibrous dysplasia, dysostoses: OI, achondroplasia, cleidocranial dysostosis Cf: platybasia (12 Dec 1998) |
| basilar lamina | A thin layer of tissue covered with mesothelial cells that separates the cochlea from the scala tympani in the ear. (18 Nov 1997) |
| basilar meningitis | Meningitis at the base of the brain, due usually to tuberculosis, syphilis, or any low-grade chronic granulomatous process; may result in an internal hydrocephalus. (05 Mar 2000) |
| basilar migraine | A migraine accompanied by transient brainstem signs (vertigo, tinnitus, perioral numbness, diplopia, etc.) thought to be due to vasospastic narrowing of the basilar artery. (05 Mar 2000) |
| basilar part of pons | The large ventral part of the pons occupied by the nuclei pontis, traversed longitudinally by corticopontine, corticobulbar, and corticospinal fibres, and transversely by pontocerebellar fibres. Pontocerebellar fibres converging laterally form the middle cerebellar peduncle or brachium pontis. Synonym: pars ventralis pontis, anterior part of pons, basilar part of pons, pars basilaris pontis. (05 Mar 2000) |
| basilar part of the occipital bone | The part of the occipital bone that lies anterior to the foramen magnum and joins with the body of the sphenoid bone. Synonym: pars basilaris ossis occipitalis, basal part of occipital bone, basilar apophysis, basilar process of occipital bone, basilar process, basiocciput. (05 Mar 2000) |
| basilar plexus | A venous plexus on the clivus, connected with the cavernous and petrosal sinuses and the internal vertebral (epidural) venous plexus. Synonym: plexus basilaris, basilar sinus. (05 Mar 2000) |
| basilar pontine sulcus | A median groove on the ventral surface of the pons varolii in which lies the basilar artery. Synonym: sulcus basilaris pontis, basilar sulcus. (05 Mar 2000) |
| basilar process | The part of the occipital bone that lies anterior to the foramen magnum and joins with the body of the sphenoid bone. Synonym: pars basilaris ossis occipitalis, basal part of occipital bone, basilar apophysis, basilar process of occipital bone, basilar process, basiocciput. (05 Mar 2000) |
