3 general classes of hormones
Steroid, protein, and amine hormones
synthesized in endocrine cells & released space into EC
Paracrine hormone
HPA Axis
Stress stimulates hippocampus to release MR and GR. The receptors of GR and MR will send feedback to the hypothalamus to release CRH and AVP. Then this will stimulate CRH and AVP to release ACTH. ACTH will stimulate the adrenal glands to release cortisol which will go to peripheral tissues.
What suppresses Growth hormone and prolactin?
Somatostatin and Dopamine
It is a hormone that acts on the maturation of follicles, ovulation, production of estrogen, progesterone, and testosterone.
Luteinizing hormone
Acts on spermatogenesis and egg cell production.
Follicle stimulating hormone
Production of adrenocortical hormones by adrenal gland.
Adrenocorticotropic hormone
It antagonizes the effects of insulin.
Growth hormone
It allows the individual to transition from fed state to a fasting state.
Growth hormone
It enhances protein synthesis in skeletal muscle and other tissues.
Growth hormone
Peak levels of growth hormone.
1-4 hours of deep sleep
It enhances growth hormone production.
IGF-1
Condition that has hyperglycemia.
Acromegaly
Laboratory diagnosis of acromegaly.
OGTT
Laboratory diagnosis of dwarfism.
Insulin tolerance test
Main stimulus for the uptake of iodide.
Thyroid stimulating hormone
Symptoms of early hypothyroidism.
Increase TSH
Important in milk letdown and maintenance of lactation.
Prolactin
Hormone in the zona glomerulosa
Aldosterone (mineralocorticoids)
Hormone in the zona fasciculata.
Cortisol (glucocorticoids)
Hormone in the zona reticularis.
Sex hormones (steroids)
The only adrenal hormone that can inhibit the production of ACTH.
Cortisol
It is anti inflammatory and immunosuppressive
Cortisol
Some symptoms are hyperglycemia, protein wasting and decreased ability to limit infections.
Cushing’s syndrome
