|---|---|---|---|
| 설명 | 뇌줄기이란 대뇌와 척수를 이어주는 다리 역할을 하는 뇌의 부분으로 이곳에는 중간뇌, 다리뇌, 숨뇌의 3개의 부분이 포함된다. 이곳은 대뇌에서 나가는 운동신경과 대뇌로 들어오는 감각신경의 중요한 통로가 있는 곳이며, 동시에 대부분의 뇌신경(척수를 거치지 않고 나가는 신경, 즉 뇌에서 직접 나오고 들어오는 신경을 이르는 말)의 중요한 요지이다. |

| 영문 | blood-brain barrier(BBB) | 한글 | 혈뇌장벽 |
|---|---|---|---|
| 설명 | 뇌와 척수에는 혈류로부터 어떤 물질이 유입되는 것을 막는 장벽이다. 이것은 뇌와 척수에 존재하는 모세혈관의 투과성이 비교적 다른 모세혈관의 투과성보다 떨어지기 때문이다. |

| 영문 | blood-brain barrier | 한글 | 혈액뇌장벽 |
|---|---|---|---|
| 설명 | 혈액으로부터 뇌로는 지질용해성이 높은 약물밖에 이행되지 않는다. 수용성의 약물을 뇌로 이행되지 않게 하고 있는 것이 혈액뇌장벽이며 뇌의 모세혈관 내피세포, 모세혈관 주위의 세포가 장벽이 되고 있다. 물질교환은 수동확산에 의해 이루어지지만, 뇌의 생리적 활동에 필요한 물질은 이온형이라도 담체를 통해 이행된다. |

| venereal tumours, veterinary | Tumours most commonly seen on or near the genitalia. They are venereal, most likely transmitted through transplantation of cells by contact. Metastases have been reported. Spontaneous regression may occur. (12 Dec 1998) |
| giant cell tumours | Tumours of bone tissue or synovial or other soft tissue characterised by the presence of giant cells. The most common are giant cell tumour of tendon sheath and giant cell tumour of bone. (12 Dec 1998) |
| pineal region tumours | Type of brain tumours. (12 Dec 1998) |

| 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) |
