Endocrine Glands Flashcards
7 endocrine glands
Pituitary Thyroid Parathyroid Pancreatic islets Adrenals Testes Ovaries
Pituitary gland
Bottom of brain
Thyroid gland
Neck below larynx
Pancreatic islets
Within the pancreas in the abdomen
Adrenals
Adjacent to kidneys
Testes
In scrotum
Ovaries
In cranial abdomen
What is the master gland
Pituitary gland
What does the pituitary gland do
Controls many parts of the body including several other endocrine glands
What hormones does the pituitary gland release
GH
AcTh
TSH
ADH
What hormones does the pituitary gland release
GH
AcTh
TSH
ADH
GH
Growth hormone
Cell growth and production
ACTH
Adrenocorticotropic hormone
TSH
Thyroid stimulating hormone
T4 and T3 prod
ADH
Antidiuretic hormone
Water reabsorption in kidneys and increased blood volume
Thyroid gland
Regulates metabolic rate (how fast/slow brain, He, liver, muscles work)
How body uses food for energy
Parathyroid gland
4
Controls how much calcium in blood vs bones
PTH (parathyroid hormone removes calcium from bone )
Pancreas as an endocrine
Islets that produce insulin/glucogen
Pancreas as an exocrine
Produces digestive enzymes
What does insulin do
Regulates blood glucose
Glucogen
Hormone released by islets if blood glucose too low, causes release of glucose from liver
Adrenal glands
One for each kidney
Made up of cortex and medulla
Cortex
Outside
Corticosteroids (cortisol- controls use of fat, protein, carbs)
Aldosterone- regulates sodium/BP
Medulla
Epinephrine/adrenaline (fight or flight) increase blood flow to heart /brain/muscles
Helps survive dangerous situations
Corticosteroids
Divided into glucocorticoids / mineralocorticoid
Glucocorticoids
Controls metabolism/ use of fat, protein, carbs
Mineralcorticoid
Regulate electrolyte water balance
Blood volume/pressure
ACTH
Pituitary gland
Acts on adrenal glands that regulate corticosteroids
Hormones testes/ovaries produce
Testosterone
Estrogen
Progesterone
What controls the ovaries
FSH and LH
Where are FSH and LH produced
Pituitary gland
