SUMMARY OF ENDOCRINE GLAND STRUCTURE Organ Division Hypophysis Adenohypophysis Par distalis Pars intermedia Pars tuberalis Neurohypophysis Pars nervosa Infundibulum Thyroid Parathyroid Adrenal Cortex Zona glomerulosa Zona fasiculata Zona reticularis Medulla Pancreas Islet of Langerhans Cell arrangement/morphology 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
