Q

What are the endocrine cells of the adenohypophysis?

A

Basophils:

  1. Thyreotropic cells - TSH
  2. Gonadotropic cells - FSH, LH
  3. Corticotropic cells - ACTH

Acidophils:

  1. Somatotropic cells - STH
  2. Mammotropic cells - prolactin

Q

What is this slide?

A

Thyroid gland (glandula thyroidea):

  • Follicles
  • Squamous to columnar epithelium
    • Depends of the secretory activity
  • Content = colloid - thyroglobulin
  • Follicular cells
  • Parafollicular cells

Q

Describe the parathyroid gland

A
  • Connective tissue captule
  • Trabecules of epithelial cells - sometimes compact masses of cells
  • Visceral type of capillaries (fenestrated)
  • Chief cells:
    • Small polygonal cells
    • Vesicular
    • Pale staining nucleus
    • Secretory granules - parathormone
    • Variable amount of glycogen
  • Oxyphil cells - darker nuclei, number of mitochondria

Q

Describe the adrenal gland

A
  • Cortex:
    • Mesodermal origin - coelomic epithelium
    • Steroid secreting cells
  • Medulla:
    • Originates from the neural crest
    • Cells produce catecholamines

Cortex:

  • Zona glomerulosa (aldosterone)
  • Zona fasciculata (glucocorticoids - cortisol, androgens)
  • Zona reticularis (androgens, glucocorticoids)
