|---|---|---|---|
| 설명 | 원형질 표면을 덮는 엷은막. 두께는 5~25μm이다. 광학현미경으로는 관찰할 수 없지만 전자현미경으로 관찰이 가능하다. 원형질막의 분자구조는 레시틴이나 콜레스테롤 등의 표면 활성물질 분자가 2분자층으로 그 표면에 배열되며, 이것을 각 1분자층의 단백질 분자가 양쪽에서 샌드위치한 단위막 구조이다. 전자현미경적으로 이 단위는 암-명-암의 3층(각 약 20nm)으로 구별된다. 원형질의 투과성에 중요한 구실을 하며, 생리상태가 변하면 그 투과성도 신속히 변한다. 또, 손상이 되면 쉽게 새로 형성된다. |

| pituitary dwarfism | Short stature due to underpreformance of the pituitary gland (specifically of the anterior pituitary). (12 Dec 1998) |
|---|---|
| pituitary fossa | Fossa of the sphenoid bone housing the pituitary gland. See: sella turcica. Synonym: fossa hypophysialis, pituitary fossa. (05 Mar 2000) |
| pituitary gigantism | Excessive growth due to overactivity of the pituitary gland (specifically of the anterior pituitary). (12 Dec 1998) |
| pituitary gland | A small oval shaped endocrine gland situated at the base of the brain in the fossa (depression) of the sphenoid bone. The overall role is to regulate growth and metabolism. The gland is divided into the posterior and anterior pituitary, each responsible for the production of its own unique hormones. (27 Sep 1997) |
| pituitary gland, anterior | The glandular or anterior lobe of the pituitary gland. (12 Dec 1998) |
| pituitary gland, posterior | The neural or post-neural lobe of the pituitary gland. (12 Dec 1998) |
| pituitary gonadotropic hormone | 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) |
| pituitary gonadotropins | gonadoprophins |
| pituitary growth hormone | <protein> Hormone (191 amino acids) released by anterior pituitary that stimulates release of somatomedin, thereby causing growth. (18 Nov 1997) |
| pituitary hormone release inhibiting hormones | Polypeptide hormones produced in the hypothalamus which inhibit the release of pituitary hormones. (12 Dec 1998) |
| pituitary hormone-releasing hormones | Hormones released by one structure (e.g., the hypothalamus or the thyroid gland) that effect the secretion of hormones from the pituitary gland. (12 Dec 1998) |
| pituitary hormones | Hormones secreted by the anterior and posterior lobes of the pituitary gland and the pars intermedia, an ill-defined region between the two. Their secretion is regulated by the hypothalamus. (12 Dec 1998) |
| pituitary hormones, anterior | Protein, glycoprotein, or polypeptide hormones secreted by the anterior lobe of the pituitary gland. (12 Dec 1998) |
| pituitary hormones, posterior | Hormones released from the posterior lobe of the pituitary, including vasopressin (antidiuretic hormone) and oxytocin. They are formed in the neuronal cells of the hypothalamic nuclei and stored in nerve cell endings in the posterior pituitary (neurohypophysis). (12 Dec 1998) |
| pituitary infantilism | Short stature due to underpreformance of the pituitary gland (specifically of the anterior pituitary). (12 Dec 1998) |
