Do hormones determine the secondary sex characteristics?
Primary sexual characteristics are those which enable a person to become capable of having children, which in girls would be menstruation and in boys the production of sperm. All other physical changes, such as growth of pubic heair and breasts etc are secondary characterists. All these changes are directly initiated and stimulated by the two hormones that you have mentioned.
What hormone signals the hormones of the adrenal cortex?
adrenaline
The adrenal cortex produces a battery of steroids (glucocorticoids and mineralocorticoids - mainly hydrocortisone and aldosterone), but it doesn't produce adrenalin. Adrenalin is released by the adrenal medulla which occupies the interior of the adrenal gland
Why is the somatomedin C test used?
The somatomedin C test is usually ordered to detect pituitary abnormalities, hGH deficiency, and acromegaly. Also called insulin-like growth factor (IGF-1)
Cabergoline is chemical that will lower prolactin levels.
Why would athletes abuse erythropoietin?
It stimulates the production of red blood cells, and as a result an athlete's blood would be able to carry more oxygen to feed working muscles, which would be a competitive advantage.
Erythropoietin
stimulates the production of red blood cells so that the blood would be able to supply working muscles with more oxygen. This can be a major advantage in all sports with a height in endurance.
Which hormones directly influence th uterus during pregnancy?
The cycle results from a balance between 4 hormones. Estrogen, Progesterone, Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH).
Progesterone is dependent on ovulation and release of the follicle for production, so the other 3 are more primarily responsible if you want to look at it that way. Progesterone is higher in the second half (luteal phase) of the cycle and maintains the endometrium lining.
Mid cycle a surge of estrogen causes the pituitary gland to release increased amounts of LH and FSH.
Do most hormones regulate by negative feedback mechanisms?
Yes and most biochemical path ways are regulated by negative feedback. Enough of the product made inhibits the enzyme, or biochemical pathway, from making more product/reactions.
Which hormone is secreted by the parathyroids?
It produces hormone parathomon. It increases the Ca level and decrease the phosphate level of bllod

What hormone affect the reproductive system?
This is quite a complicated question. Hormones are chemicals produced in one part of the body that causes changes elsewhere in the body. Around puberty, the pituitary gland, along with the hypothalamus produces hormones to turn on the gonads (ovaries or testes). Hormones target hormone receptors which are either on the cell walls or on the nucleus, and the receptors tell the cells to alter their function. Then the gonads start producing hormones which are testosterone in male and estrogen and progesterone in females. Those hormones target the receptors designed for them, and those cells alter in function or even multiply in number. For instance, there are stem cells for breast growth, and in females, the estrogen tells those cells to unpack part of their DNA to use, and also to divide and thus proliferate.
Also, it is estrogen that causes the bone growth to finish, and yes, in males too. Males only produce estrogen as excessive testosterone is broken down. So the bone caps close later than in females.
Where are the target cells for follicle-stimulating hormone?
Hello Both are produced in the anterior pituitary gland as well as PRL, ACTH, TSH and GH. Oxitocin and ADH are SECRETED from the posterior pituitary and produced in the hypothalamus
Hormones that regulate the secretory action of other endocrine glands are called ____________.?
Tropins regulate the secretory action of other endocrine glands.
What are normal values for an adrenocorticotropic hormone test?
Normal values at 8 a.m. are 6 - 23 mcg/dL.
Note: mcg/dL = micrograms per deciliter
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
Why is it important for progesterone level to remain high if a woman is pregnant?
Without high level of estrogen and progesterone, pregnancy can not continue and and abortion will occur. So many times your Gynecologist will give you depot preparation of progesterone weekly to continue pregnancy.
Glucagon is released when blood sugar levels are low, like when someone is fasting. It is released into the bloodstream by the alpha cells in the islets of langerhans in the pancreas. It causes the liver to convert the stored glycogen that it has into glucose. That glucose is released into the blood and increases the blood sugar level of the body.
