1. Endocrine System Histology and Models

2. ENDOCRINE SYSTEM Questions
Function of the endocrine system: to maintain homeostasis
Thymus gland: cortex and medulla (site of maturation of white blood cells)
Thyroid gland (secretes thyroid hormone and calcitonin)
Parathyroid gland (secretes parathyroid hormone, which increases blood calcium)
Adrenal gland: Capsule, cortex (secretes aldosterone to increase salt reabsorption which raises blood pressure, androgens and estrogens, and cortisol); medulla (secretes epinephrine)
Pituitary gland:
Posterior pituitary (AKA neurohypophysis or pars nervosa) secretes oxytocin and ADH
Anterior pituitary (AKA adenohypophysis or pars distalis) secretes MSH, GH, ACTH, PRL, TSH, LH, FSH. (melons grow and produce through late fall)
Pineal Gland: Pinealocytes, pineal sand (secretes melatonin)
