|
T3 and T4 consist of
|
Iodine, w amino acids and tyrosine. The benzyne ring of thyrosine and iodine = lipid soluble
|
|
|
Seratoinin and Melatonin are derived from
|
Triptophane
|
|
|
Pepticle and Proteins are synthesized on
|
Endoplasmic Reticulum and consist of 3 to 200 amino acids, some w/ carbohydrate group
|
|
|
Isonides are derived from
|
Arachnoid Acid, with 20 carbons
|
|
|
2 Important Isonides are
|
1. Prosteglandins
2. Lucotrienes Both are local hormones |
|
|
The 3 functions of transport proteins are
|
1. make more transportable
2. prevent horone loss through kidneys 3. provide reserve of hormone in blood |
|
|
Protein that are no problem are
|
water soluble...they move freely and mix w/ plasma easily
|
|
|
Proteins that must link to transport protein in liver are
|
lipid soluble
|
|
|
Anterior Pituitary secretion are regulated by the
|
Hypothalamus
|
|
|
THe Hypothalamus secretes
|
5 releasing hormones
2 inhibitory hormones |
|
|
The 5 releasing hormones secreted by Hypothalamus are
|
1. HGH releasing
2. Thyroid releasing 3. Gonadotropin releasing 4. Prolactin releasing 5. Corticotropin releasing |
|
|
The 2 inhibitory hormones secreted by the Hypothalamus are
|
1. Growth Hormone inhibitory
2. Prolactin Inhibitory |
|
|
HGH, the most abundant hormone stimulates
|
Liver, Skeletal Muscle, Cartilage, Bone, and Tissue
|
|
|
HGH causes production of
|
IGF's Insulin like Growth Hormones
|
|
|
IGF's
|
stimulate cell growth, multiply bu increasing amino acid uptake and protein synthesis, and decrease protien breakdown and ATP production
|
|
|
Low glucose level = release of
|
GHRH
|
|
|
High glucose level = release of
|
GHIH
|
|
|
FSH production in females=
|
development of follicles, and estrogen secretion
|
|
|
FSH production in males=
|
development of sperm
|
|
|
GNRH and FSH release in females is supressed by
|
Estrogen
|
|
|
GNRH and FSH release in males is supressed by
|
Testosterone
|
|
|
Leuitenizing hormone in females stimulates
|
estrogen release, ovulation, progesterone, and corpus luteum
|
|
|
Leutinizing hormone in males stimulates
|
testosterone production and release
|
|
|
During menstruation
|
estrogen, progesterone, and PIH level fall which makes prolactin levels rise
|
|
|
During pregnancy
|
PRH causes prolactin levels to rise
|
|
|
During nursing of infant
|
causes reduction of PIH,but prolactin levels remain high
|
|
|
Beta Cells
|
constitute 70% of pancreatic islet cells and secrete Insulin
|
|
|
Alpha Cells
|
constitute 17% of pancreatic islet cells and secrete Glucagon
|
|
|
Delta Cells
|
constitute 7% of pancreatic islet cells and secrete Somatostatin ( identical to GH)
|
|
|
F Cells
|
constitute reaminder and secrete pancreatic polypeptide
|
