The pituitary gland consists of 2 endocrine glands anterior lobe-adenohypohysis, posterior lobe-neurohypopysis
another name for the anterior lobe is adenohypohsis
another name for posterior lobe neurohypopsis
Hormones of the anterior are stimulated by what?? releasing hormones of hypothalamus,suppressed by inhibiting hormones
what connects the pituitary to the hypothalamus & is the means by which regulatory hormones travel to pituitary Hypophyseal portal system
What is LTH(Lactogenic hormone or lutetropic hormone)& where is it prolcatin, it is in the anterior pituitary gland
What does prolactin promote during pregnant- breast development after delivery- initiates milk secretion
What does prolactin help maintain Corpus Luteum
What is the growth hormone Somatotropic
What does somatrotropic do?? & where is it accelerates protien anabloism(synthesis), & promotes growth & in the anterior pituitary gland
What parts are sensitive to somatotropic skeletal muscle cells & Chondrocytes
What disorder is caused by deficient somatotropic dwarfism
what does liver & other cells produce ?? insunlike growth factors (IGF'S) that increase amino acid uptake
Hormones that have a stimulating effect on other endocrine gland is called Tropic Hormones
What is thyrotropins & where is it Thyroid stimulating hormone (TSH), in the anterior pituitary gland
What does TSH do promotes growth & development of thyroid gland , stimulates thyroid gland to secrete thyroid hormone ( throxine)
What is ACTH & where is it Adrencorticotropin in the anterior pituitary gland
What does ACTH do?? promotes growth & development of adrenal cortex, stimulates cortex to secrete cortisol & other glucorticoids
What does follicle-stimulating hormone(FSH) do & where is it stimulates graafian follicle to start to grow & mature,Stimulates follicle cells to secrete estrogen {egg formation}, in the anterior pituitary gland

What controls the secretion of hormones hypothalmus
What are releasing hormones neurosecretions produced in the hypothalmus that reach anterior pituitary gland via blood in piturary portal system
What does the releasing hormone do regulates hormone production
where does the negative feedback mechanisms operate? btwn target glands & anterior lobe of putitary
