Pituitary Hormones: Posterior Pituitary & Anterior Pituitary
The pituitary gland, also known as hypophysis, is a small pea-sized gland about 1 cm in diameter and 0.5 to 1 gram in weight. The pituitary gland resides in a small bony cavity situated at the base of the brain, known as sella turcica, and a pituitary stalk (infundibulum) maintains a connection between the pituitary gland and hypothalamus. The secretion of hormones by the pituitary gland is und...

متن کاملBiological characteristics of two transplantable pituitary tumors of Syrian hamsters.
appear to be common in the Syrian hamster. Among thirteen spontaneous tumors occurring in one series of a thousand hamsters of unspecified age, none were of pituitary origin (1). No pituitary tumors were reported among 226 animals autop sied at the end of a normal life span, although the majority of these old hamsters had both benign and malignant neoplasms which were frequently multiple (2). O...
متن کاملPurification of anterior pituitary and hypothalamic hormones.
Pure preparations of pituitary and hypothalamic hormones are needed mainly for (1) their chemical characterisation, which increases our understanding of their biochemistry and makes their synthesis possible; (2) replacement therapy, in which contamination with other pituitary hormones is undesirable; and (3) the development of specific diagnostic assays. Pituitary hormones were first isolated f...
متن کاملUpdate: brain and pituitary hormones of lampreys.
Lampreys and hagfish of the class Agnatha are of particular importance in understanding endocrinological relationships since they represent the oldest lineages of extant vertebrates which evolved over 550 million years ago. This review briefly summarizes the latest findings on the reproductive endocrinology of the sea lampreys. Since the First International Symposium of Fish Endocrinology in 19...
