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
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
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
stimulate cell growth, multiply bu increasing amino acid uptake and protein synthesis, and decrease protien breakdown and ATP production
Low glucose level = release of
High glucose level = release of
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
GNRH and FSH release in males is supressed by
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
