|---|---|---|---|
| 설명 | 혀를 비롯한 구강 점막의 일부에 분포하는 미각 수용기. 맛신경의 종말기가 되는 작은 구조이다. 꽃봉오리 모양이며, 높이 약80㎛, 너비 약40㎛이다. 입 특히 혀점막의 유두 속에 많이 분포한다. 물렁입천장이나 후두개의 상피 속에서도 흔히 볼 수 있다. 맛봉오리의 대부분을 차지하며 외주부에 있는 것이 지지세포이며 난원형의 핵을 가진다. 내부에 있는 지지세포는 꼿꼿하므로 기둥세포라고도 한다. 미세포는 맛봉오리 내부에 있고 간상이며, 굵은 중간 부분에 핵이 들어 있다. 맛봉오리는 장축을 가지고 점막 상피 안에 들어 있으며, 그 유리 표면에 작은 구멍이 있다. 맛봉오리신경은 혀의 뒤쪽 1/3과 엽상유두에는 혀인두신경으로부터, 혀의 앞 2/3에는 고삭신경에서 온 신경으로 맛봉오리 안에서 끝나는 맛봉오리 내 섬유와 맛봉오리 밖의 상피 내에서 끝나는 맛봉오리 간 섬유로 나뉜다. 맛봉오리가 미각에 관계하는 것은 사실이지만 모든 미각이 맛봉오리에 의존하는 것은 아니다. 타닌 등의 떫은 맛은 혀와 구강점막 전체가 자극되어 일어나는 감각이며, 맛봉오리와는 관계가 없다. |

| bud fission | 1. <biology> The formation of a new individual, either animal or vegetable, by a process of budding; an asexual method of reproduction; gemmulation; gemmiparity. See Budding. 2. <botany> The arrangement of buds on the stalk; also, of leaves in the bud. Origin: Cf. F. Gemmation. Source: Websters Dictionary (01 Mar 1998) |

| binary fission | <cell biology> Division of a cell into two daughter cells after DNA replication and nuclear division (mitosis). A form of asexual reproduction. (09 Oct 1997) |
|---|---|
| multiple fission | Division of the nucleus, simultaneously or successively, into a number of daughter nuclei, followed by division of the cell body into an equal number of parts, each containing a nucleus. (05 Mar 2000) |
| simple fission | Division of the nucleus and then the cell body into two parts. See: binary fission. (05 Mar 2000) |
| nuclear fission | Nuclear reaction in which the nucleus of a heavy atom such as uranium or plutonium is split into two approximately equal parts by a neutron, charged particle, or photon. (12 Dec 1998) |
| fission | A type of cell division in which overall (i.e., not localised) cell growth is followed by septum formation which typically divides the fully grown cell into two similar or identical cells. (09 Oct 1997) |
| fission fungi | <biology> An order of Schizophyta, including the so-called fission fungi, or bacteria. See Schizophyta, in the Supplement. Origin: NL, fr. Gr. To split +, -, a fungus. Source: Websters Dictionary (01 Mar 1998) |
| fission product | An atomic species produced in the course of the fission of a larger atom such as 235U. (05 Mar 2000) |
| fission reactor | <radiobiology> A device that can initiate and control a self-sustaining series of nuclear fissions, typically used for either research or the production of energy or nuclear weapons materials. (09 Oct 1997) |
| fission yeast | <fungus> Species of fission yeast commonly used for studies on cell cycle control because there is a distinct G2 phase to the cycle. Only distantly related to the budding yeast Saccharomyces cerevisiae Saccharomyces cerevisiae. A further advantage is that some mammalian introns are processed correctly. (18 Nov 1997) |
| fusion-fission hybrid | <radiobiology> Proposed nuclear reactor relying on both fusion and fission reactions. A central fusion chamber would produce neutrons to induce fission in a surrounding blanket of fissionable material. The neutron source could also be used to convert other materials into additional fissile fuels (breeder hybrid). Safer than a plain fission reactor because the fission fuel relies on the fusion neutrons, and therefore cannot achieve criticality. On the other hand, hybrids are more complex because of the fusion power core, and still generate fission's radioactive byproducts. But a fusion-fission hybrid could be more economical and have less stringent technical requirements than a pure fusion reactor. (05 Jan 1998) |
| bronchial bud | One of the outgrowths from the primordial endodermal laryngotracheal tube giving rise to the primary bronchi. See: laryngotracheal diverticulum. (05 Mar 2000) |
| bud | <botany> A small swelling or projection on a plant, from which a shoot, cluster of leaves, or flowers develops, a rudimentary, undeveloped shoot, leaf, or flower. (09 Oct 1997) |
| bud stage | First stage of tooth development; development of the primordia of the enamel organs, the tooth buds. (05 Mar 2000) |
| vascular bud | An endothelial sprout arising from a blood vessel. (05 Mar 2000) |
| mary-bud | <botany> The marigold; a blossom of the marigold. Source: Websters Dictionary (01 Mar 1998) |
