Hormone
Cells in cords around large-bore capillaries: Acidophils
Basophils
Mostly basophilic cells around cystic cavities
Narrow sleeve of basophilc cells around Infundibulum
Growth hormone, prolactin
ACTH, TSH, FSH, LH
ACTH
LH
Nerve fibers and supporting cells (pituicytes)
Oxytocin and vasopressin (produced
in hypothalamus)
Nerve fibers (traveling from hypothalamus to pars nervosa)
Follicles: Simple cuboidal to columnar epithelium in spherical shells
around colloid
Densely packed cords of polygonal cells (chief cells and oxyphilic cells)
Principal cells: T3 and T4
Parafollicular cell: Thyrocalcitonin
PTH
Columnar cells in rounded clusters
Large, pale-staining polygonal cells in columns
Round cells in irregular cords
Aldosterone
Glucocorticoids (Cortisone)
Gonadocorticoids (DHEA)
Chromaffin cells= large round cells with centrally located nucleus with
prominent nucleus, often cytoplasmic granules. Note large veins in
center of medulla.
Irregularly arranged cells with many capillaries
Norepinephrine and epinephrine
Insulin, glucagon
