Posterior Pituitary Gland
(neuronhypohysis)secretes which two hormones |
Oxytocin and ADH
|
|
|
What is oxytocin
|
Paraventicular nuclei- hormone in neurophysis that stimulates milk ejection and uterine contractions.
|
|
|
What is ADH
|
Superoptic nuclei-Antiduretic hormone increase peremability of kidney tubules to water, results in waters conservation through decrease urine output, homestastis of blood volume, blood pressure, and heart rate.
|
|
|
Naturally produced morphine-lie compound secreted by anterior pituitary
|
Beta-endorphines and Enkephalins
|
|
|
What two hormones control the level of GH released and where are they secreted from
|
GNRH and somatostatin in the hypothalamus
|
|
|
The secretion of GnrH by the hypothalamus will stimulate the anterior pituitary to secrete
|
FSH and LH
|
|
|
List Hypothalamus release, pituitary releases, and the gland that it secretes
|
Coritsol-CRH-Corticotrophins Releasing Hormone-ACTH-adrenal cortex
Testosterone-Ant. Pit- LH-LH acts on the interstitial cells of the testes. Thyroxine-TSH-Throid Parathyroid-PTH Hormone-thyrocalcintonin-into blood stream |
|
|
Steps in Angiotensin System
(hint 10) |
decrease in blood volume
decrease in blood pressure juxtagomerular appartus detects change in BP. Angiotenesis is converted to Angio I. Ang I is converted to Angio II. Widespread, vasconstriction and release of aldosterone. Increased permeability of the kidney tubules to sodium. Osmoreceptors change is detected by post.pit. ADH is released. Increased permeability of kidney tubules to H2O . |
|
|
What happens when adrenal medulla is stimulated
|
increased cardiac output and dilated coronary blood vessels.
|
|
|
What are the effects of cortisol
|
causes widespread vasocnstriction and decreases capillary permeability and inhibits osteoblas synthesis
|
|
|
What is function of parathyroid hormone
|
stimulate osteoclast activity
|
|
|
another function fo PTH
|
stimulating the reabsorption of calcium
|
|
|
What is function of MSH
|
stimulate melanocytes production of melanin
|
|
|
the adrenal cortex secrete which hormones
|
cortisol and aldosterone
|
|
|
FSH stimulate whatin the male and female
|
male-spermatogenesis
female-oogenisis and follice cell philiferation |
|
|
What hormone is responsible for the development of primary sex characteristics
|
testosterone
|
|
|
Oxytocin is to___ as prolaction is to milk ___
|
ejection, production
|
|
|
What is the funciton of LH in male and female
|
male-interstitial cells of testes.
females-follicle cells-Estrogen and Progestron and ovulation |
|
|
Following structures that arise from male, female
|
Genital tubercle- male-glas penis, female-clitoris
Genital fold-male-shaft of penis, female-labia minora Genital swelling-male-scrotum, female-labia majora |
|
|
What are the steps in the female cycle
|
Day 1 Menstruation
Negative Feedback E&P levels fall off. FSH from Ant Pit Follicle cell proliferation LH from Ant Pit Stim follicle cell to produce E& P stim endometrium thicken Day 14 Positive Feedback E causes a urge in LH Ovulation P is increased; maintaining endometrium than E As levels of P fall off, endometrium shed. |
|
|
erythropoietin sitmulates what which means
|
erythropoiesis, Red blood cell production
|
|
|
thymosin is secreted by and stimulates
|
thymus, production and differientiation of T-cells
|
|
|
what stimulates the production of erythropoietin
|
kidneys detect a decrease in partial pressure of oxygen
|
|
|
alpha cells secrete what in response to low BS and stimulate
|
glucagon. glucogenolysis-break of glycogen
|
|
|
beta cells secrete what in response to high BS and stimulate
|
insulan. glucogenolysis and cells take up
|
|
|
cortisol stimulates the process of glucogenesis in response to low BS
|
or inhibility to use glucose
|
