Discuss the endocrine changes in women during pregnancy

  ENDOCRINE CHANGES IN WOMEN DURING PREGNANCY The placenta secretes hormones during pregnancy, indeed throughout pregnancy, plasma concentrations of estrogen and progesterone steadily rises; and these hormones come from the placenta. To start with, by the time the blastocyst implants in the uterine wall and the placenta tarts to form, the corpus luteum is approaching […]

Describe the role of anterior and posterior pituitary in milk production and release

THE ROLE OF  ANTERIOR AND POSTERIOR PITUITARY IN MILK PRODUCTION AND RELEASE The anterior pituitary contains a cell population called lactoropes. These cells secrete prolactin. The lactoropes are under the influence of other factors. Prolactin-inhibiting factor (dopamine) secreted by the hypothalamus inhibits the lactoropes. Prolactin-releasing factors (PRF) released by the hypothalamus stimulates the lactoropes to […]

Describe the hypothalamo-pituitary gland link

Describe the hypothalamo-pituitary gland link   THE HYPOTHALAMO-PITUITARY GLAND LINK This thin connecting stalk links the hypothalamus with the pituitary gland. However, the hypothalamo-pituitary link consists of two components: 1. neural connections between the hypothalamus and the posterior lobe of the pituitary gland; via the hypothalamo-hypophyseal tract 2. vascular link that connects the hypothalamus and […]

Write an essay on the hypophysiotropic hormones and their regulation of secretion

  HYPOPHYSIOTROPIC HORMONES Hypophysiotropic hormones are hormones released by the hypothalamus, which act on the anterior pituitary either to stimulate or to inhibit the secretion of this gland. These hormones are released by neurons found in the hypothalamus. The process by which a neuron releases a hormone is termed neurosecretion. Hypophysis = “pituitary”; tropic = […]

List and state briefly the functions of the anterior pituitary hormones

ANTERIOR PITUITARY HORMONES In contrast to the posterior pituitary that releases hormones manufactured by the hypothalamus, the anterior pituitary manufactures the hormones it releases into blood. Different cell types within the anterior pituitary secrete six known peptide hormones. The table below shows the hormones and the cell types that secrete them HORMONE CELL TYPE 1. […]
