Endocrine Flashcards
(38 cards)
Types of hormone molecules
Amino acids. Peptides. Lipids
Endocrine system function
Regulate and control hormonal activity.
Tissue that hormones affect
Target
Location if steroid hormone
Target cells inner cell membrane surface
Non steroid hormones location
Plasma membrane outer surface
Effects of prostaglandins
Relax or contract smooth muscle
Decrease hydrochloric acid production
Clot blood
Coordinate cell activities
Negative feedback
A deviation from a set point is corrected by moving in the opposite direction
Pituitary gland
Base of brain
Sella turcica
Hanging from stalk
Has anterior and posterior part
GH (growth hormone)
Stimulate cell growth in size and number and replication
Altered amounts of GH result in
Gigantism and dwarfism
PLR (prolactin hormone)
Produce milk in mammary gland
Largest TSH tissue
Thyroid
Target tissue of FSH (follicle stimulating hormone)
Gonads
FSH in males and females
Sperm maturation
Egg production
LH (luteinizing)
Sex hormone secretion
ADH (anti diuretic hormone)
Tells kidneys to conserve water
Causes diabetes if not secreted
Oxytocin
Contract uterus sperm duct prostate and ejects milk
Thyroid relies on
Iodine
Thyroid produces hormones that
Metabolize and use oxygen
Adrenal glands secrete
Epinephrine and norepinephrine
Adrenaline
Increase heart rate blood pressure and blood glucose
Aldosterone
Conserves sodium ions in kidneys
Glucocorticoids in times of stress
Increase rate of glucose formation and have anti inflammatory response
Pancreas as endocrine and exocrine gland
Glucagon and insulin
Pancreatic juice
