07 Endocrine Marvelyn Breceda 6th period anatomy
Include the hormones and their functions and their target organs :check:
Thyroid gland
Follicular cell produce 2 iodire-containing hormones
hormones are essential for normal/growth
regulate metabolism
parathyroid gland
releases calcuim to the blood
pth stimulates the kidneys to conserve calcium
Pth increases blood caicim ion concerntration and decreases phosphate
pituitary hormone
growth horomonee
stimulates body cells to grow and reproduce
speeds rate,cells use carbohydrates and fats
Pancreas
Insulin drecreases the blood level of glucose
control level of blood glucose
glucagon increases the blood level
Compare and contrast steroid vs. non-steroid hormones and list the hormones for each
category :check:
Non-steriod
hormone is called first messanger
chemicals in the cell that responds to binding of hormone
Combine with receptor in target cell membranes
steriod hormone
are lipid-soluble, they pass through sell membranes
carried in bloodstream weakly bound to plasma proteins
Protein receptor for steriods are located inside target cells
Major endocrine glands/organs and their functions (separate by region / body cavity) :check:
Parathyroid gland
A negative feedback mechanism involving blood calcium level regulates release of pth
Adernal glands
Cells of the adernal cortex produce over 30 steriods some of which are hormone vital to survive
Thyroid gland
Thyroid gland consists of secretory units called follicles,filled with hormone-storing colloid
Pancreas
Secretes hormones as an endocrine gland, and digesr juice into the digestive tract as an exocrine gland pancreatic hormone control level of blood glucose
pituitary gland
attached to hypothalamus by a stalk called the infundibulum
reproductive gland
Ovaries and testes
Pineal gland
Secretes melatonin, is involved in the regulation of circadian rhythms of the body
Kidney
Secrete erythropoietin for blood cell preoduction
Thymus gland
Secretes thymosin, that affect production and different action of T lymphocytes
Major functions of the endocrine system :check:
works with the nervous system to maintain homeostasis
Organs are not anatomically adjacent to each other
Hormones diffuse into bloodstream to act on specific target cells some distance away
Homeostatic mechanisms of hormone regulation (negative and positive feedback) :check:
Negative feedback
horemone level rises, hormone exerts its efffects, further seceretionis inhibited by negative feedback then hormone section decresed
a gland is sensitive to the concentray=tion of substance it regulates
release of hormone from hypothalamus
controls secerations of the anterior pituitary
Diseases associated with the endocrine system :check:
made up by cells , tissues and organs
hormones regulate a number of metabolic processes withn cells
diabetes2
Diabetes 1
