11th: Chemical Coordination Flashcards
(26 cards)
Pituitary gland is divided into
Pars diastalis, pars intermedia, pars nervosa
Pituitary hormone function
Regulate growth and development of somatic tissues and activities of peripheral endocrine glands
Pineal gland secretes
Melatonin
Melatonin function
Diurnal rhythms
Thyroid gland hormones function
Regulation of basal metabolic rate, development and maturation of CNS, erythropoiesis, metabolism of carbs, proteins and fats, menstrual cycle.
Thyrocalcitonin function
Regulates calcium level in our blood by decreasing it
Parathyroid gland function
PTH secretion, increases the Ca2+ levels
Thymus gland secretion and function
Thymosins: differentiation of T-lymphocytes. Increases the antibody production
Adrenal gland composed of
Centrally located adrenal medulla and outer adrenal cortex
Adrenal medulla secretion and function
Epinephrine and norepinephrine: increase alertness, pupillary dilation,piloerection,sweating,heartbeat,strength of heart contraction,rate of respiration,glycogenolysis,lipolysis,proteolysis.
Adrenal cortex secretion
glucocorticoids and mineralocorticoids.
Glucocorticoids stimulate
Stimulate gluconeogenesis, lipolysis, proteolysis, erythropoiesis,
cardio-vascular system, blood pressure, and glomerular filtration rate.
Glucocorticoids inhibit
inflammatory reactions by suppressing the immune response.
Mineralocorticoids function
regulate water and electrolyte contents of the body.
endocrine pancreas secretes
glucagon and insulin.
Glucagon stimulates causing
glycogenolysis and gluconeogenesis
resulting in hyperglycemia.
Insulin stimulates resulting in
cellular glucose uptake and
utilisation, and glycogenesis resulting in hypoglycemia.
Insulin deficiency result in
diabetes mellitus
Androgens are secreted by and their function
testis -stimulate the development, maturation
and functions of the male accessory sex organs, appearance of the male secondary
sex characters, spermatogenesis, male sexual behaviour, anabolic pathways and
erythropoiesis.
ovary secretes
estrogen and progesterone.
Estrogen stimulates
growth and development of female accessory sex organs and secondary sex
characters
Progesterone plays a major role in
the maintenance of pregnancy as
well as in mammary gland development and lactation
The atrial wall of the heart
produces .
atrial natriuretic factor which decreases the blood pressure
Kidney produces
erythropoietin which stimulates erythropoiesis
