How are protein hormones transported in the blood - ANS-Protein hormones are water
soluable, and circulate in free forms (unbound). **Proteins have a short half life

What is oxytocin? - ANS-a polypeptide hormone released by the pituitary gland that
responds to stressful stimuli, especially in pregnant women

What is the relationship between oxytocin and the pituitary gland - ANS-Oxytocin is
stored in, and secreted by the posterior pituitary gland

What are the effects of oxytocin - ANS-in females: stimulates the uterine contractions of
childbirth and milk ejection from the mammary glands
in males: may facilitate sexual behavior and the transport of sperm
-promotes bonding

Know ADH - ANS-It acts on vasopressin receptors of the renal tubule, causing and
increase in their permeability.

^^ H2O in blood= concentrated urine = reduced serum osmolality

Where is ADH secreted? - ANS-It is produced by the hypothalamus

It is stored in, and secreted by the posterior pituitary

Where are the target cells for Thyrotropin releasing hormone (TRH) - ANS-Anterior
Pituitary Gland

where are the target cells for Somatostatin - ANS-Anterior Pituitary Gland

Where are the target cells for Growth Hormone-Releasing Hormone - ANS-Anterior
Pituitary Gland

Gland

Where are the target cells for Corticotropin Releasing Hormone - ANS-Anterior Pituitary

Where are the target cells for Substance-P - ANS-Anterior Pituitary

, Where are the target cells for Dopamine - ANS-Anterior Pituitary Gland

Where are the target cells for prolactin releasing Hormone - ANS-Anterior Pituitary
Gland

Where are the target cells for Prolactin-inhibiting Hormone - ANS-Anterior Pituitary
Gland

Where are the target cells for ACTH - ANS-Adrenal Glands

Where are the target cells for melanocyte stimulating hormone (MSH) - ANS-Anterior
pituitary Gland

Where are the target cells for Growth Hormone - ANS-Muscle, bone, liver

Where are the target cells for Prolactin - ANS-Breasts

Where are the target cells for Thryoid Stimulating Hormone - ANS-Thyroid Gland

Where are the target cells for Lutenizing Hormone (LH) - ANS-> Men - testes

> Women - Ovaries (Leydig cells)

Where are the target cells for Folicle Stimulating Hormone (FSH) - ANS-> Men - Testes

> Women - Ovaries

Where are the target cells for Lipotropin - ANS-Adipose Cells

Where are the target cells for Endorphins - ANS-Adipose cells &

Brain opioid receptors

What is the role of calcitonin - ANS-Released by the thyroid gland, it acts to lower
serum calcium by inhibiting bone reabsorbing osteoclasts

It is used to treat osteoporosis, osteoarthritis, pager bone disease, hyper Alice is,
osteogenesis imperfecta, and metastatic cancer of the bone

What is the role of TSH? - ANS-Acts on the Thryoid gland to:
1) immediately increase the release of Thryoid Hormone
2) increase in iodine uptake and oxidation
3) increase Thryoid synthesis
4) increase synthesis and secretion of prostaglandins
5) increase growth of the Thryoid gland
