| 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. |

| 영문 | pineal gland | 한글 | 솔방울샘, 송과선 |
|---|---|---|---|
| 설명 | 뇌의 중앙선부위의 등쪽에 존재하는 내분비기관이다. 솔방울샘은 melatonin을 분비한다. 동물에서는 성분화발달에 기여하는 것으로 되어 있으나, 사람에서는 그 기능이 아직 명확치 않다. |

| 영문 | prostate gland | 한글 | 전립샘 |
|---|---|---|---|
| 설명 | 남성생식기의 외분비샘의 일종으로, 방광의 목부분과 요도를 둘러싸고 있다. 전립샘은 정액을 만드는 전립샘액을 분비하며 5개의 엽으로 구성되어 있다. |

| 영문 | salivary gland | 한글 | 침샘, 타액선 |
|---|---|---|---|
| 설명 | 입 속으로 침을 분비하는 외분비샘으로 인체에는 세 쌍의 침샘이 있는데 귀밑샘, 턱밑샘 및 혀밑샘이 그들이다. 침샘은 분류상으로 소화기계통의 한 장기이며, 소화관의 한 부속샘으로 구분된다. 혀밑샘은 그 외 구강 점막 내에 산재하고 있는 수많은 작은 침샘과 같이 묽은 용액을 끊임없이 분비하고 있지만, 귀밑샘과 턱밑샘은 자극을 받을 때만 침을 분비한다. |

| ethmoid infundibulum | A passage from the middle meatus of the nose communicating with the anterior ethmoidal cells and frontal sinus. Synonym: infundibulum ethmoidale, ethmoid infundibulum. (05 Mar 2000) |
|---|---|
| anterior pituitary gonadotropin | Any gonadotropin of hypophysial origin; formerly used to designate a single hormone, because it was thought that the anterior hypophysis secreted only one gonadotropin. Synonym: pituitary gonadotropic hormone. (05 Mar 2000) |
| anterior pituitary-like hormone | A glycoprotein with a carbohydrate fraction composed of d-galactose and hexosamine, extracted from the urine of pregnant women and produced by the placental trophoblastic cells; its most important role appears to be stimulation, during the first trimester, of ovarian secretion of the oestrogen and progesterone required for the integrity of conceptus; it appears to play no significant role in the last two trimesters of pregnancy, as the oestrogen and progesterone are then formed by the placenta. Synonym: anterior pituitary-like hormone, choriogonadotropin, chorionic gonadotropic hormone, chorionic gonadotrophic hormone, placenta gonadotropin, placentagonadotropin. (05 Mar 2000) |
| receptors, pituitary hormone | Cell surface proteins that bind pituitary hormones with high affinity and trigger intracellular changes influencing the behaviour of cells. Since many pituitary hormones are also released by neurons as neurotransmitters, these receptors are also found in the nervous system. (12 Dec 1998) |
| receptors, pituitary hormone-regulating hormone | Cell surface receptors that bind the hypothalamic hormones regulating pituitary cell differentiation, proliferation, and hormone synthesis and release, including the pituitary-releasing and release-inhibiting hormones. The pituitary hormone-regulating hormones are also released by cells other than hypothalamic neurons, and their receptors also occur on non-pituitary cells, especially brain neurons, where their role is less well understood. Receptors for dopamine, which is a prolactin release-inhibiting hormone as well as a common neurotransmitter, are not included here. (12 Dec 1998) |
| pharyngeal pituitary | The embryonic remnant of the oral end of Rathke's pouch that is cut off from the adenohypophysis by the developing sphenoid bone; composed chiefly of chromophobes and, under normal conditions, considered physiologically inactive. See: hypophysis. (05 Mar 2000) |
| pituitary | <anatomy, endocrinology> An endocrine gland located at the base of the brain, in the small recess of a bone - certain sections of the pituitary each secretes important hormones including growth hormone (GH) and antidiuretic hormone (ADH). (16 Dec 1997) |
| pituitary adamantinoma | <oncology, tumour> A form of primary brain tumour which develops in the pituitary gland. These tumours often secrete increased quantities of pituitary hormones (for example growth hormone) which can result in conditions such as gigantism and acromegaly. They are often benign and rare and comprise less than 5% of childhood brain tumours. Other symptoms include vision changes, headache and weight gain. Treatment often includes a combination of surgery and radiation therapy. (27 Sep 1997) |
| pituitary adenoma | <radiology> Benign, slow-growing, arises from adenohypophysis (anterior lobe), 5-18% of all intracranial neoplasms plain film (unreliable): enlargement of sella and sloping of the sella floor, erosion of the anterior and posterior clinoid, erosion of the dorsum sellae, calcified in less than10%, may present as a mass in the nasopharynx functioning microadenoma, less than10 mm, 20-30% of pituitary adenomas, types: prolactinoma, corticotrophic adenoma, somatotrophic adenoma, nonfunctioning macroadenoma, more than 10 mm, 70-80% of pituitary adenomas (12 Dec 1998) |
| pituitary-adrenal system | The interactions between the anterior pituitary and adrenal glands, in which corticotropin (acth) stimulates the adrenal cortex and adrenal cortical hormones suppress the production of corticotropin by the anterior pituitary. (12 Dec 1998) |
| pituitary ameloblastoma | <oncology, tumour> A form of primary brain tumour which develops in the pituitary gland. These tumours often secrete increased quantities of pituitary hormones (for example growth hormone) which can result in conditions such as gigantism and acromegaly. They are often benign and rare and comprise less than 5% of childhood brain tumours. Other symptoms include vision changes, headache and weight gain. Treatment often includes a combination of surgery and radiation therapy. (27 Sep 1997) |
| pituitary apoplexy | Sudden haemorrhage into or ischemic necrosis of a normal or adenomatous pituitary gland. (12 Dec 1998) |
| pituitary cachexia | Anterior pituitary insufficiency due to trauma, vascular lesions, or tumours; usually developing postpartum as a result of pituitary necrosis caused by ischemia during a hypotensive episode during delivery; characterised clinically by asthenia, loss of weight and body hair, arterial hypotension, and manifestations of thyroid, adrenal, and gonadal hypofunction. Synonym: hypophysial cachexia, pituitary cachexia. (05 Mar 2000) |
| pituitary diverticulum | A tubular outgrowth of ectoderm from the stomodeum of the embryo; it grows dorsad toward the infundibular process of the diencephalon, around which it forms a cup-like mass, giving rise to the pars distalis and pars juxtaneuralis of the hypophysis. Synonym: craniopharyngeal canal, hypophyseal pouch, Rathke's diverticulum, Rathke's pocket, Rathke's pouch. (05 Mar 2000) |
| pituitary dwarf | Dwarfism as result of failure of growth hormone production because of hypothalamic or pituitary abnormality. Synonym: pituitary dwarf. (05 Mar 2000) |
