Unit 3 tissues Flashcards
The Pituitary Gland
Parts:
Adenohypophysis (Pars tuberalis, Pars distalis, Pars intermedia)
Neurohypophysis (Pars nervosa and Infundibulum)
Between = hypophyseal cleft.
Cells of the pars distalis
Acidophils (Somatotropes and Lactotropes)
Basophils (Thyrotropes, Gonadotropes, Corticotropes)
Chemophobes (either reserve or degranulated forms of acidophils or basophils)
The Pineal gland
Ependymal cells
BRAIN SAND = calcium phosphate or calcium carbonate deposits.
The thyroid gland
Follicular cells and parafollicular cells
Parathyroid gland
Two = external and internal glands
Chief cells and oxyphil cells
The adrenal gland
Cortex (zona glomerulosa, zona fasciculata, zona reticularis)
Medulla
Islet of Langerhauns of the Endocrine Pancreas
Alpha, Beta, C, delta, and F cells
Enteroendocrine cells of the small intestine
