| 설명 | 중추신경계의 한부분으로 주로 생명유지 기능과 연관된 일을 하는 아주 중요한 기관이다. 대뇌에서 내려온 신경이 소뇌와 합쳐서 척수로 내려가는 부분에 위치해 있다. 밖에서 보면 머리 뒤쪽의 아래에 해당하는 위치한다. 3가지의 중요한 기능을 담당한다. 1)호흡조절 기능: 호기와 흡기의 조절을 행하며, 어떤 자극이나, 혹은 산소의 감소, 이산화탄소의 증가를 감지하여 호흡이 원활하게 이루어질 수 있도록 해준다. 호흡에 관여하는 자극을 감지하는 기관은 여기 연수 부위와 체내의 내, 외경동맥혈관 사이에 존재하는 목동맥소체(carotid body) 2군데로 나뉘어져 있는데 중추기관에서의 주자극은 이산화탄소의 증가이고, 말초기관(즉, 목동맥소체)의 주자극은 산소의 감소이다. 2)심장의 운동 조절: 원래 심장은 자동성이 있어 스스로 뛰는 경향이 있는데, 이를 운동이나, 휴식에 알맞도록 그 박동수 등을 조절한다. 3)혈관운동 조절: 혈관벽에 존재하는 근육 등을 조절하여 혈압이 유지되도록 한다. 숨뇌가 파괴되면 대개는 죽는다. 만약 심장이 뛰는 상태에서 숨뇌만 사라진다면, 흔히 말하는 뇌사상태가 된다. 즉, 스스로 호흡할 수 없고, 자극에 반응이 없어지는 단계에 이르게 된다는 것이다. 만약 위의 고위 중추기관(대뇌, 소뇌 등)이 죽고, 숨뇌만이 파괴되지 않았다면, 이때는 흔히 말하는 식물인간상태(vegetative state)가 되어 목숨은 있으나, 전혀 인간적인 활동을 할 수 없는 상태가 되는 것이다. 무엇보다 숨뇌는 생명유지에 가장 필수적인 기관이다.  |

| gigantocellular nucleus of medulla oblongata | One of the three major nuclei of the reticular formation of the brainstem. Synonym: nucleus gigantocellularis medullae oblongatae. (05 Mar 2000) |
| medulla oblongata | The lowest subdivision of the brainstem, immediately adjacent to the spinal cord. Houses important cardiac and respiratory regulatory centres. (27 Sep 1997) |
| posterior median fissure of the medulla oblongata | The longitudinal groove marking the posterior midline of the medulla oblongata; continuous below with the posterior median sulcus of the spinal cord. Synonym: sulcus medianus posterior medullae oblongatae, posterior median fissure of the medulla oblongata. (05 Mar 2000) |
| posterior median sulcus of medulla oblongata | The longitudinal groove marking the posterior midline of the medulla oblongata; continuous below with the posterior median sulcus of the spinal cord. Synonym: sulcus medianus posterior medullae oblongatae, posterior median fissure of the medulla oblongata. (05 Mar 2000) |
| sensory decussation of medulla oblongata | The intercrossing of the fibres of the left and right medial lemniscus ascending from the gracile and cuneate nuclei, immediately rostral to the level of the decussation of the pyramidal tracts in the medulla oblongata. Synonym: decussatio lemniscorum, decussatio sensoria, decussation of the fillet, sensory decussation of medulla oblongata. (05 Mar 2000) |
| pyramid of medulla oblongata | An elongated, white prominence on the ventral surface of the medulla oblongata on either side along the anterior median fissure, corresponding to the pyramidal tract. Synonym: pyramis medullae oblongatae, anterior column of medulla oblongata, anterior pyramid. (05 Mar 2000) |

| lateral nucleus of medulla oblongata | A group of cells in the medulla oblongata, located between the inferior olive and the descending trigeminal nucleus, receiving fibres from the spinal cord and motor cortex and projecting to the cerebellum. Synonym: nucleus lateralis medullae oblongatae, lateral reticular nucleus. (05 Mar 2000) |
| animal | 1. An organised living being endowed with sensation and the power of voluntary motion, and also characterised by taking its food into an internal cavity or stomach for digestion; by giving carbonic acid to the air and taking oxygen in the process of respiration; and by increasing in motive power or active aggressive force with progress to maturity. 2. One of the lower animals; a brute or beast, as distinguished from man; as, men and animals. Origin: L, fr. Anima breath, soul: cf. F. Animal. See Animate. 1. Of or relating to animals; as, animal functions. 2. Pertaining to the merely sentient part of a creature, as distinguished from the intellectual, rational, or spiritual part; as, the animal passions or appetites. 3. Consisting of the flesh of animals; as, animal food. Animal magnetism. See Magnetism and Mesmerism. Animal electricity, the electricity developed in some animals, as the electric eel, torpedo, etc. <physiology> Animal flower, the heat generated in the body of a living animal, by means of which the animal is kept at nearly a uniform temperature. Animal spirits. See Spirit. Animal kingdom, the whole class of beings endowed with animal life. It embraces several subkingdoms, and under these there are Classes, Orders, Families, Genera, Species, and sometimes intermediate groupings, all in regular subordination, but variously arranged by different writers. The following are the grand divisions, or subkingdoms, and the principal classes under them, generally recognised at the present time: - Vertebrata, including Mammalia or Mammals, Aves or Birds, Reptilia, Amphibia, Pisces or Fishes, Marsipobranchiata (Craniota); and Leptocardia (Acrania). Tunicata, including the Thaliacea, and Ascidioidea or Ascidians.

| animal cell culture | <cell culture> Mammalian cells are fragile and harder to grow than other cell types, but their large-scale culturing is an economic boon because it allows for the production of proteins that are otherwise difficult or expensive or unethical to extract from living organisms. The cells are immobilised on a substrate and then perfused with culture medium, The cells are in a free suspension which is very gently mixed and aerated. (12 Nov 1997) |
| animal cell immobilisation | <cell culture> Animal cells are widely used in biotechnology to produce genetically engineered proteins. However, they are more fragile than bacterial cells, and immobilising the cell facilitates the fermentation process. Many animal cells stick down flat on a suitable surface, hugging it as they would hug other cells or connective matrices in the body. If grown on suitable plastic surfaces, on glass or many ceramics, these cells will stick to them. In this way, they are easier to grow. (14 Nov 1997) |
