Term
| (R) estrogen & progesterone |
|
Definition
class:steroid
source: ovaries
target: gametes
effect:bone/heart; oocyte development; promote/retain pregnancy |
|
|
Term
|
Definition
class:steroid
source: testes
target: gametes
effect: sperm production; secondary male characteristics |
|
|
Term
(R) FSH
Follicular Stimulating Hormone |
|
Definition
class:amino acid
source: anterior pituitary
target: ovary/testes
effect:(F) promotes development of follicle and oocyte
(M) promotes sperm development and differentiation |
|
|
Term
(R) LH
Leutinizing Hormone |
|
Definition
class:amino acid
source: anterior pituitary
target: ovary/testes
effect: promotes hormone release (testosterone, progesterone, estrogen) |
|
|
Term
|
Definition
class: amino acid
source: posterior pituitary
target: uterus smooth muscle (myometrium)
effect:(+) feedback: uterine contractions->childbirth |
|
|
Term
(U) Vasopressin/ADH
Antidiuretic Hormone |
|
Definition
class:amino acid
source:posterior pituitary
target: kidney tubules
effect: stimulates water conservation at kidneys=decrease urine output--> maintains BP and Blood Volume |
|
|
Term
|
Definition
class:amino acid
source: atria of heart
target: kidney tubules
effect:secrete Na+= increase urine concentration=decrease BP&V |
|
|
Term
|
Definition
class: amino acid
source: kidney JG cells
target: kidney tubules
effect:increase BP by sensing decreases in BP
feed into Renin-Angiotensin=Restore BP |
|
|
Term
|
Definition
class: amino acid
source:hypothalamus
target: anterior pituitary
effect:
(U) depends on Releasing Hormone
(R) allows release of FSH and LH (control reproduction) |
|
|
Term
(U) ACTH
AdrenoCorticoTropic Hormone |
|
Definition
class: amino acid
source: anterior pituitary
target: adrenal cortex
effect:releases corticosteroids |
|
|
Term
| (U) Epinephrine, Norepinephrine |
|
Definition
class:steroid
source: adrenal cortex
target: liver
effect:stimulates metabolism, inflammatory response
Glucose Release=EDEMA |
|
|
Term
(U) Mineralocorticoids
Aldosterone |
|
Definition
class:steroid
source: adrenal
target: kidney tubules
effect:maintains sodium balance, resorbs Na+= Increase BP&V
increases filtration rate (water follows) |
|
|
Term
(U) Calcitonin
ton of calcium |
|
Definition
class: amino acid
source: thyroid C-Cells
target: kidney, bone
effect: stimulates osteoblasts to LOWER blood calcium |
|
|
Term
(U) PTH
Parathyroid Hormone |
|
Definition
class: amino acid
source: parathyroid
target: kidney, bone, intestine
effect: stimulates osteoclasts, kidney, and intestinal resorption of CA++(vit. D)
INCREASES blood calcium |
|
|
Term
|
Definition
allows release of LH, FSH
stimulates Ovaries |
|
|
Term
| (+) Feedback in Reproductive System |
|
Definition
high estrogen stimulates anterior pituitary
Burst of LH at midcycle= OVULATION
ruptured follicle becomes corpus luteum, produces progesterone/estrogen |
|
|
Term
| (-) Feedback in Reproductive System |
|
Definition
(on anterior pituitary) no FSH/LH=no new follicles
LH declines: corpus luteum degenerates, estrogen/progesterone decline |
|
|
Term
|
Definition
produced in anterior pituitary
binds receptors on leydig cells
stimulates production of testosterone=secondary sexual characteristics |
|
|
Term
|
Definition
produced in anterior pituitary
stimulates sertoli cells
binds and concentrates testosterone
begins spermatogenesis |
|
