3 classes of chemical structure |
Amino acid derivitate- thyroid hormones catecholamines Peptide- pancreas insulin and glucogon oxytocin Steriods- cholesterol androgen cortisol |
|
|
Epinephrine action |
Primary action- muscle glycogen - lactate Secondary action- liver glycogen to glucose |
|
|
Function of epinephrine |
Activate adenyl c yclase in the presence of Mg to hydrolyse ATP to cAMP Hydrolysis triglycerides to form FFA |
|
|
Function of cAMP |
Convert inactive protein kinase to active protein kinase |
|
|
Function of ATP |
Convert inactive phosphorylase kinase in the presence of Ca to phosphorylase kinase |
|
|
Phosphorylase a |
Formed from phosphorylase b Covert glycogen to glucose |
|
|
Glucogon |
Acts only on the liver Proglucogon until amino acids are removed |
|
|
Progesterone |
Produce by the corpus luteum and the placenta |
|
|
Function of progesterone |
Implementation of the zygote Inhibit uterine contraction Allow pregnancy to go to full term Prevents spontaneous abortion Stimulate the growth of breast and uterus Increase body temperature |
|
|
Estrogen |
Estrone estradiol estriol Ovary- E1 and E2 Placenta- E1 E2 E3 in second a third trimester |
|
|
Function of estrogen |
Influence t he proper development maintenance and functions of reproductive organs sexual activity cycle Secondary sec characteristics |
|
|
Estrogen on cardiovascular system |
Increase HDL increase platelet aggregation Decrease clotting time Help in the menstrual cycle yo prevent haemorrhage |
|
|
Estrogen effects on metabolism |
Lipogenesis Allows for the distribution of fat across the body for shape and form Increase in HDL Increase blood triglycerides Increase protein synthesis |
|
|
Effects of estrogen on reproductive system |
Maintenance of the menstrual cycle Promote growth of breast uterus overy and vagina Synthesis of progestron rceptors |
|
|
Androgen |
Testosterone Produce by laying cells and adrenal cortex |
|
|
Active metabolite of androgen |
5 alpha dihydotestosteron |
|
|
Function of androngen |
Imfluence the proper development maintenance and function of reproductive system and secondary sex characteristics |
|
|
Androgen effects on specific tissue |
Sperm formation and delevery Enlargement and thickening of the vocal cords Hair distribution Increase muscle and bone mass due to its ability to retain nitrogen from protein bone maturation Male behavior Cessation of growth |
|
|
Cortisol as an anti-inflammatory |
Interferes with normal cellular processes Wound healing Inflammation Growth |
|
|
Use of cortisol in surgery |
Suppression of immune system for organ transport Allergies and asthma Increase resistance |
|
|
Aldosterone |
Acts on DCT increase Na Decrease H and K |
|
|
Cortisol |
Catholic actions Increase amino acids |
|
|
A chain on the insulin |
21 aa Interchain disulphide ridge |
|
|
Two mechanisms that protect insulin |
Down regulation Negative corperactivity- once insulin bind the other receptors will have a lessor affinity for insulin |
|
|
Fasting blood glucose level |
6.7 mmol/l 120mg/dl |
