Endo-Pituitary, thyroid, parathyroid Flashcards
Anterior Pituitary control
hormones travel from the hypothalamus via hypophyseal portal to anterior pituitary
Posterior Pituitary Control
receives hormone via hypothalamic-hypophyseal tract, released into the blood stream by posterior pituitary
Anterior Pituitary hormones (adenohypophysis)
Thyroid stimulating hormone - TSH
Adrenocorticotropic Hormone - ACTH
Follicle Stimulating Hormone - FSH
Luteinizing Hormone - LH
Growth Hormone - GH
Prolactin
Thyroid Stimulating Hormone (TSH)
stimulates thyroid to release T3/T4
Adrenocorticotropic Hormone (ACTH)
stimulate adrenal cortex to release cortisol and aldosterone
Follicle Stimulating Hormone (FSH)
Stimulates gonads to form gametes (ova/sperm)
Luteinizing Hormone (LH)
prompts testosterone synthesis, triggers ovulation
Growth Hormone (GH)
stimulates bone, cartilage and muscle growth
Prolactin (PRL)
stimulates breast milk production
Posterior Pituitary produces what kinds of Hormone
Antidiuretic Hormone
Oxycotin
Antidiuretic Hormone (ADH)
increase blood pressure by causing a reduction in urine production
Oxycotin
Intensifies contractions during labor
prompts milk let down
promotes bonding in sexual partners and babies
Fuctions of Thyroid gland hormones
T3, T4- increase BMR (basal metabolic rate)
Calcitonin- reduces blood calcium levels
T3, T4 hormone
requires Iodine to complete hormone, 90% is T4, T3 enzymatically converts to T4
Parathyroid Gland
Parathyroid Hormone- increase blood calcium levels, stimulate osteoclasts prompting bone resorption
