Endocrine Flashcards
ACTH- adrenal cortex
Anterior pituitary
Growth hormone
Anterior pituitary
TSH
Anterior pituitary
Prolactin- milk production
Anterior pituitary
FSH- production of ova and sperm
Anterior pituitary
LH- stimulates testes and ovaries
Anterior pituitary
ADH- kidneys. Water production
Posterior pituitary
Oxytocin- uterus and mammary glands
Contraction of uterus and milk let down reflex
Posterior pituitary
Thyroxin
Thyroid
Calcitonin
Thyroid
Parathyroid hormone- blood calcium level
Parathyroid
Thysomin- t lymphocytes
Thymus
Glucagon- raises blood glucose
Glucagon glycogen glucose
Pancreas
Insulin- lowers blood glucose
Pancreas
Glucocorticoid- steroid. Resist long term stressors
Adrenal cortex
Aldosterone- steroid. Increase sodium absorption
Adrenal cortex
Epinephrine- muscle, blood vessels
Adrenal medulla
Estrogen
ovary
Progesterone- uterus and breasts
Ovary
Testosterone
Testes
EPO- bone marrow
Kidney
Cholecalciferol- intestines. Active transport
Skin
hCG- uterus. Maintain pregnancy
Placenta
5 ways hormones can bring about change within a cell
Stimulating mitosis. Change membrane permeability. Synthesis of proteins. Activation of enzymes. Promotion of secretory activity.
Direct gene activation
Diffuse through target cells plasma membrane. Enters nucleus. Binds to specific protein. Binds to specific site on cells DNA. activate genes causing synthesis.
Second messenger system
Hormone binds to membrane receptor. Doesn’t enter cell. Causes reactions that activate enzymes. Catalyzes reaction to produce 2nd messenger molecule. Oversees additional intracellular changes to promote specific response.
Pineal
Melatonin- regulates sleep and wake
_________ acts as a hypoglycemic agent
Insulin
