Hormones Flashcards
Produced in hypothalamus (and heart, blood vessels etc). Stimulate contractions, milk ejection etc). Also a neuro transmitter: promotes bonding, endorphins, socialising (tend and befriend/rest and digest). Love Hormone. One of four main labour hormones.
OXYTOCIN
Produced in hypothalamus, controls fluid retention and blood pressure. Also a neurotransmitter: promotes aggression, self defence (fight flight freeze).
VASOPRESSIN (ADH)
Produced in the Thyroid. Regulated by the Hypothalamus-pituitary gland axis. Controls metabolic rate, use of lipids/glucose.
T3 & T4
Produced in the Thyroid. Decrease calcium levels in the blood. Promotes calcification.
CALCITONIN
Produced in the Parathyroid glands. Increases calcium levels in the blood. Trigger Vitamin D production, increasing absorption of calcium from food in the small intestine.
PARATHYROID HORMONE
Produced in the adrenal cortex. Regulated by the Hypothalamus-pituitary gland axis. Controls BP and blood volume (together with Renin and Angiotensin)
ALDOSTERONE
Produced in the adrenal cortex. Regulated by the Hypothalamus-pituitary gland axis. Increase levels of calcium in the blood, levels of glucose produced in the liver and available to the cells, ups BP.
CORTISOL
Produced in the adrenal cortex. Regulated by the Hypothalamus-pituitary gland axis. Increase libido. In men stimulates growth of prostate, muscle, hair.
ANDROGENS
Produced in the adrenal medulla. Controlled by the Nervous system. Stimulates release of Cortisol. Increase HR, heart output, BP. Relaxes smooth muscle in airways, directs blood to essential organs. Works on alpha and beta receptors, heart, lungs, arteries. Stress hormone. One of four main labour hormones.
ADRENALINE
Produced in the adrenal medulla. Controlled by the Nervous system. Stimulates release of Cortisol. Increase HR, cardiac output, BP. Relaxes smooth muscle in airways, directs blood to essential organs. Works on beta receptors only, arteries. Stress hormone.
NORADRENALINE
Produced in the Pancreas, by beta cells. Regulated by environmental factors. Decrease glucose in the blood through allowing entry to cells where it is used as fuel.
INSULIN
Produced in the Pancreas, by alpha cells. Regulated by environmental factors. Increases glucose in blood. Induces glycolysis, production of glucose in the liver.
GLUCAGON
Produced in the Pancreas, by delta cells and in the brain. Regulated by environmental factors. Blocks Insulin, Glucagon, Growth hormone but not Cortisol. Also a neuro transmitter: slows down the digestive system. During stress, this hormone makes sure that glucose levels are regulated by the adrenal glands.
SOMATOSTATIN
Produced by the Pituitary gland after release of gonadotropin (GnRH) from Hypothalamus, acting on the Ovaries. Stimulates ovulation.
LEUTENIZING HORMONE (LH)
Produced by the Pituitary gland after release of gonadotropin (GnRH) from Hypothalamus, acting on the Ovaries. Stimulates follicles to grow.
FOLLICLE STIMULATING HORMONE (FSH)
