The posterior part of the pituitary has its embryological origins in nervous tissue. The pars nervosa looks like brain tissue, which it is. The pars intermedia is very poorly developed in the human pituitary, but is prominent in the pituitaries of most other mammals. The anterior pituitary produces hormones that directly stimulate the mammary glands, the adrenal glands, the thyroid, and the ovaries or testis. The anterior pituitary secretes five different types of hormone. Cells of the pars intermedia also produce POMC pro-opiomelanocortinwhich in these cells is processed primarily into endorphins and MSH melanocyte stimulating hormone. Explain how structures seen in the thyroid gland, at both the light and electron microscope levels, are involved in the production of thyroglobulin, its storage, and its subsequent breakdown to yield thyroid hormones.

Histology of the Adenohypophysis. The bulk of the adenohypophysis is pars distalis. That tissue is composed of winding cords of epithelial cells flanked by. This slide displays the three cell types of the anterior pituitary under H&E stain. The acidophils appear as cells with pink cytoplasm and dark nuclei; these cells.
Be able to identify the parts of the pituitary gland, and describe their embryological origin.
Histologically they look the same. There are three versions of slide that show a rodent thyroid at three different levels of functional activity: 1 normal [example]2 hypoactivity due to hypophysectomy [example]and 3 hyperactivity Webscope ImageScope due to treatment with the drug thiouracil.

|Acidophils include somatotropes produce growth hormone and mammotropes produce prolactin.
FSH target is the follicular cells of the ovaries, to promote growth of follicles, or the sertoli cells of the testes to promote spermatogenesis. Loss of ACTH would lead to the collapse of the adrenal cortex and a nearly complete loss of production of glucocorticoids and some weak androgens.
Cells of the pars intermedia also produce POMC pro-opiomelanocortinwhich in these cells is processed primarily into endorphins and MSH melanocyte stimulating hormone. Jump to: Pituitary Gland Suggested Readings.

You will not be required to identify these cell types in electron micrographs, but should note that the cells differ in size, shape and in the number, size and distribution of their secretory granules small black structures in the cytoplasm. Adrenal Gland Suggested Readings.
