Anterior Pituitary Makes:
1. Growth Hormone which affects bones & muscles to produce growth.
2. Prolactin which affects the breast for milk secretion.
3. Adrenocorticotropic Hormone which affect adrenal glands to
(a) make aldosterone which affects the kidney to cause it to conserve sodium.
(b) to make cortisol which affects body cells causing stress.
(c) to make androgens which affect the axilla producing hair growth.
4. Thyroid hormone which affects the thyroid to make thyoxine. This acts on body cells and increases metabolism.
5. Gonadotropic Hormones (LH, FSH) which affect the testes causing them to make testosterone. This in turn affects body cells producing male secondary sex
characteristics. This same hormone affects the ovaries to make estrogen which again affects body cells which in turn produce female secondary sex
characteristics. Both males and females make these two sex hormones.
The third effect is on the ovaries to make progesterone which acts on the uterus to maintains pregnancy.
Post Pit makes:
1. Oxyotocin which acts on the breast to cause the breasts to "let down" milk. It also causes the uterus to contract.
2. Antidiuretic hormone which acts on the kidney to conserve water

What is the function of pituitary?
formation of antidiuretic hormone
What part of the brain is involved in control of antidiuretic hormone?
The Posterior Pituitary secretes oxytocin and vasopressin, which is antidiuretic hormone.
What hormones pass through the hypothalamo-hypophyseal portal system?
Prolactin-inhibiting hormoneThe Prolactin-inhibiting hormone
Why would a person have thyroid problems if his anterior pituitary gland was damaged?
Anterior pituitary secretes the hormone THS. That is thyroid stimulating hormone. In absence of the anterior pituitary the hormone is not secreted by the thyroid and you get the hypothyroidism.
What pituitary hormone increases permeability of collecting ducts to water?
Antidiuretic hormone
WHat trophic hormones are secreted by the anterior pituitary gland?
No not all hormones produced by the anterior pituitary are growth hormones. Growth Hormone is released by the anterior pituitary and it in not a tropic hormone.
How does GnRH get from the hypothalamus to the anterior pituitary and what effects does it have on the pituitary?
The hypophysial portal system carries gonadotropin-releasing hormone (GnRH) from the hypothalamus to the anterior pituitary. It stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary.
Which hormone is secreted by the hypothalamus and stored in and released by the pituitary gland?
antidiuretic hormone (ADH)
Where does the growth hormone synthesize?
It is synthesized in pituitary. It is the anterior pituitary.
What gland secretes antidiuretic hormone?
Posterior pituitary, produced in the hypothalamus
Does the anterior pituitary secrete growth hormone?
Yes, the anterior pituitary secretes growth hormone. It's made by the acidophilic cells.
What hormone signals the kidney to make less urine?
That hormone is called ADH or antidiuretic hormone. Diuresis means producing urine and antiduresis is the opposite.
