Endocrine System Flashcards
What does the pineal gland do?
Produces melatonin. Makes you sleepy at night time. Combats stress. Improves sleep. Regulates sleeps cycle.
What does melatonin do?
Regulates sleep cycle
What does the thyroid gland do?
Produces thyroid hormones (T3 +T4) and Calcitonin. Increases cell metabolism. Growth and neural development.
What does the T3 hormone do?
Tissue growth, oxygen consumptions. Regulates temperature. Protein synthesis. metabolism
What does the T4 hormone do?
Prohormone for T3.
What does calcitonin do?
Lowers blood calcium levels. Stimulates calcium absorption by the bone.
What does the parathyroid gland do?
Makes PTH (parathyroid hormone).
What does PTH do?
Stimulates the release of calcium from the bone. Stimulates calcium absorption by the gut and kidney. Raises blood calcium by telling bones to release calcium + the intestines to absorb calcium.
What does the Adrenal cortex do?
Creates glucocorticoids and mineralocorticoids.
What do glucocorticoids do?
They all end in the letters “cortisol”. They help with long-term metabolic responses to stress and anti-inflammatory responses.
What do mineralocorticoids do?
All end in the letters “aldosterone”. Involved in salt and water balance.
What does the adrenal medulla do?
Produces epinephrine and norepinephrine. (adrenaline and noradrenaline). Stimulates immediate flight or flight reactions.
What do the ovaries do?
Release estrogen and progesterone.
What do estrogen and progesterone do?
estrogen - development/maintenance of female sexual parts. progesterone - supports pregnancy
What do the testes do?
Makes androgens (testosterone).
