| 영문 | gland | 한글 | 샘 |
|---|---|---|---|
| 설명 | 자신의 대상에 필요가 없는 물질을 만들어 분비하는 세포가 모여서 만드는 구조. 즉 분비물을 제조하는 세포가 모인 것이다. 선에는 내분비샘과 외분비샘의 2가지가 있다. 내분비샘이란 몸밖이 아닌 내부, 즉 직접 혈중으로 분비물을 분비하는 샘으로 이 때에 분비되는 물질을 호르몬이라고 한다. 이것은 주로 몸안의 다른 세포에 작용을 하여 그 세포의 대사, 분열 등의 변화를 초래하고 몸의 환경의 변화에 따른 적응을 돕는 역할을 한다. 외분비샘이란 몸밖으로 관구조를 통하여 분비물을 내보내는 샘을 말한다. |

| crossed pyramidal tract | Those fibres of the pyramidal tract that cross to the opposite side in the pyramidal decussation and descend in the dorsal half of the lateral funiculus of the spinal cord; they are distributed throughout the length of the spinal cord to interneurons of the zona intermedia of the spinal gray matter. See: pyramidal tract. Synonym: tractus corticospinalis lateralis, tractus pyramidalis lateralis, crossed pyramidal tract, fasciculus corticospinalis lateralis, fasciculus pyramidalis lateralis, lateral corticospinal tract, lateral pyramidal fasciculus.

| pyramidal | 1. Of or pertaining to a pyramid; in the form of a a pyramid; pyramidical; as, pyramidal cleavage. "The mystic obelisks stand up Triangular, pyramidal."

| pyramidal cells | Projection neurons in the cerebral cortex and the hippocampus. Pyramidal cells have a pyramid-shaped soma with the apex and an apical dendrite pointed toward the pial surface and other dendrites and an axon emerging from the base. The axons may have local collaterals but also project outside their cortical region. (12 Dec 1998) |

| pyramidal eminence | A conical projection posterior to the vestibular window in the middle ear; it is hollow and contains the stapedius muscle. Synonym: pyramid of tympanum, pyramidal eminence, pyramis tympani. (05 Mar 2000) |
