name the types of cellular signaling and give and example of each....
|
1. Neural- BP control, influence of leptin on central autonomic control
2. endocrine- almost every organ in body (blood borne chemical messengers) 3. neuroendocrine- adrenal gland (norepi and epi) and post. pituitary- vasopressin and oxytocin 4. paracrine- NO 5. autocrine |
|
|
endocrine structures and hormones secreted that are peptide hormones
1. hypothalamus- 2. Anterior pituitary- 3. posterior pituitary- 4. Thyroid- 5. Parathyroid- |
1. hypothalamus- TRH, CRH, Dopamine (PIF), GHRH, Somastatin (GHiH), GnRH
2. Anterior pituitary- GH, TSH, ACTH, Prolactin, FSH, LH 3. posterior pituitary- ADH, Oxytocin 4. Thyroid- calcitonin 5. Parathyroid- PTH |
|
|
With the following hormones name the source and when released what it does...
a. TRH Thyrotropin-releasing hormone b. Prolactin inhibitory factor (PiF) or dopamine c. CRH Corticotropin-releasing hormone |
all these are from the hypothalamus and via portal system go to anterior pituitary
a. TSH, prolactin b. inhibits prolactin (dopamine is a tyrosine derivative and therefore an Amine hormone not a peptide) c. ACTH |
|
|
With the following hormones name the source and when released what it does...
a. GHRH Growth hormone-releasing hormone b. Somatostatin i.e. Growth hormone inhibitory hormone (GHiH) c. GnRH gonatotropin-releasing hormone (GnRH) |
a. GH
b. inhibits GH and TSH c. FSH, LH |
|
|

a. prolactin |
a. inhibits GnRH released from anterior pituitary
|
|
|

a. insulin and glucagon
b. erythropoietin c. ANP and BNP d. angiotensin |
|
|
endocrine structures and hormones secreted that are peptide hormones
a. GI b. Adipocytes |
a. gastrin, secretin, CCK
b. leptin |
|
|
endocrine structures and hormones secreted
a. adrenal cortex b. testes c. ovaries |
these are all steroid hormones
a. cortisol, aldosterone b. testosterone c. estrogen, progesterone |
|
|
endocrine structures and hormones secreted that are amine hormones
a. thyroid b. adrenal medulla |
a. thyroxine
b. epinephrine and norepinephrine |
|
|
Give an example of hormone concentration regulation that is fairly constant
|
T3/T4
|
|
|
specific example of positive feedback control
|
LH and estrogen... increase Estrogen increased LH which increased Estrogen until you get ovulation... in which case negative feedback is initiated
