lipid soluble hormones
Ans: -steroid and thyroid hormones
-act on intracellular receptors that directly activate genes
-can enter cell
- will change gene and lead to the synthesis of new mRNA
water soluble hormones
Ans: (all amino acid-based hormones except thyroid hormone)
Act on plasma membrane receptors
Act via G protein second messengers
Cannot enter cell
levels of hormones in blood regulation

hormone concentration in blood
abundance of target cells
influences exerted by other hormones

permissive effect: two hormones work together to get a big
effect
antagonistic effect: two hormones opposing the actions of the
other
Growth Hormone (GH) - anterior pituitary
Ans: secretes insulin-like growth factors which synthesize in
the liver and go to the blood and attach on target cells to
secrete growth
Thyroid Stimulating Hormone (TSH)- anterior pituitary
Ans: stimulates synthesis and secretion of thyroid hormones (
T3 and T4)
hypothalamus controls this hormone by secreting its o wn
thyrotropin releasing hormone
Adrenocorticotropic hormone (ACTH)
Ans: Stimulates adrenal cortex to secrete glucocorticoids
(mainly cortisol)
hypothalamus regulates it

Follicle-stimulating hormone (FSH)- anterior pituitary
Ans: secreted by the pituitary gland to stimulate maturation of
the egg cell (ovum) and for males to stimulate sperm
production
luteinizing hormone (LH)- anterior pituitary
Ans: Targets gonads, causes development of corpus luteum,
testes make testosterone
posterior pituitary hormones
Ans: antidiuretic hormone and oxytocin
Osmoreceptors
Ans: respond to the osmolarity of the blood (water
homeostasis)
follicular and parafollicular cells of thyroid
Ans: T4 and T3 by follicular
calcitonin by parafollicular
