• Pars tuberalis
• Pars intermedia

29.  POSTERIOR PITUITARY OR NEUROHYPOPHYSIS

32. o Pars nervosa
• Also called the neural lobe or posterior lobe, this region constitutes the
majority of the posterior pituitary and is the storage site of oxytocin and
vasopressin.
• Sometimes (incorrectly) considered synonymous with the posterior pituitary,
the pars nervosa includes Herring bodies and pituicytes
• Herring bodies or neurosecretory bodies are structures found in the posterior pituitary.
They represent the terminal end of the axons from the hypothalamus, and hormones are
temporarily stored in these locations. They are neurosecretory terminals.
• Pituicytes are glial cells of the posterior pituitary. Their main role is to assist in the storage and
release of neurohypophysial hormones

35. oInfundibular stalk
• Also known as the infundibulum or pituitary stalk, the infundibular stalk
bridges the hypothalamic and hypophyseal systems.
, part of the inferior boundary of the hypothalamus in
the brain, is attached to the infundibulum.
• The median eminence is a small swelling on the tuber cinereum, posterior to
and atop the pituitary stalk.
• It lies in the area roughly bounded on its posterolateral region by the cerebral
peduncles, and on its anterolateral region by the optic chiasm.

43. THYROID GLAND

56. PARATHYROID GLANDS

60. ADRENAL (SUPRARENAL) GLANDS

67. production of aldosterone, a mineralocorticoid.
Zona fasciculata
Situated between the glomerulosa and reticularis, the cells of the zona
fasciculata synthesize and secrete glucocorticoids
Zona reticularis
The inner most cortical layer, the zona reticularis produces androgens.

68. • Glucocorticoids
• mineralocorticoids
• sex hormones (androgens)

69. adrenaline and nor adrenaline
