What is correct to say about the hormone action in humans?
Glucagon is secreted by -cells of Islets of Langerhans and stimulates glycogenolysis
Secretion of thymosine is stimulated with ageing

Identify the hormone with its correct matching of source and function.
Oxytocin - posterior pituitary, growth and maintenance of mammary glands.
Melatonin - pineal gland, regulates the normal rhythm of sleep-wake cycle
Progesterone - corpus luteum, stimulation of growth and activities of female secondary sex organs
Progesterone - corpus luteum, stimulation of growth and activities of female secondary sex organs
Fight or flight reactions cause activation of
the parathyroid glands, leading to increased metabolic rate
the kidney, leading to suppression of reninangiotensin - aldosterone pathway
the adrenal medulla, leading to increased secretion epinephrine and norepinephrine
the adrenal medulla, leading to increased secretion epinephrine and norepinephrine
C.
the adrenal medulla, leading to increased secretion epinephrine and norepinephrine
Fight or flight reaction is a physiological reaction that occurs in response to an emergency. Emergency hormone are secreted by adrenal medulla of adrenal gland secretes adrenaline (epinephrine) and nor alternative (norepinephrine) hormones which stimulate sweating, heart beat and breathing rate. These also cause dilation of coronary artery ( for increasing inspiratory volume)and pupil (for better vision)
