Endocrine System Flashcards
Pituitary
HGH - growth MSH - melanin ACTH- adrenal vortex LTH- milk during lactation (prolactin) FSH- ovaries to product oestrogen and men to produce sperm LH- ovaries to produce corpus luteum ICSH- sperm and testosterone ADH- water regulation in kidney Oxytocin
Thyroid
Thyroxin
Triiodothyronine
Calcitonin balance calcium and phosphorous - hyper secretion causes calcium level to drop and release from bones
Parathyroid
Parathormone
Maintains calcium level and stimulate calcium reabsorption
Activates vitamin D
Adrenal glands
Mineralocorticoids
Regulate salt in the body
Glucocorticoids such as cortisol
Metabolise carbs and fats and proteins
Sex hormone
Adrenal medulla
Adrenaline and nor adrenaline
Pancreas
Insulin and glucagon
Ovaries
Oestrogen and progesterone
Pineal glans
Melatonin body rhythms
Thymus in thorax
Thymus factor TF
Thymic Humoral Factor THF
Immunity
Girls puberty age
10-14
Boys puberty age
13-16
Ovaries stimulated by
FSH and LH
Anterior lobe pituitary
Puberty in boys
Through luteinising hormone FSH and LH are produced which stimulates testosterone
Start of menstruation is
Menarch
3 stages of menstruation
Menstrual - 5 days
Progesterone enters blood and less LH produced. Corpus luteum breaks down and progesterone level falls. Lining starts to break
Proliferation 7 days
FSH stimulates ovaries to produce oestrogen which stimulates lining of womb to create new blood vessels and then ovulation occurs
Secretory stage 14 days
LH stimulates growth of corpus luteum which produces progesterone stimulating endometrium to retain fluid
