|
Where are the the neurons in charge of releasing or inhibitory factors?
|
ventral hypothalamus
|
|
|
Which hypothalmic nuclei controls the release of oxytocin?
|
paraventricular nuclei
|
|
|
Which hypothalmic nuclei controls the release of oxytocin?
|
supraoptic nuclei
|
|
|
What connects the neurons in the pituitary gland to the hypothalamus?
|
infundibulum stalk
|
|
|
What part of the posterior pituitary gland stores hormones?
|
neurohypophysis
|
|
|
What hormones are released through the anterior pituitary gland?
|
TSH, FSH, LH, ACTH, GH, RPL
|
|
|
What hormones are released through the posterior pituitary gland?
|
ADH (supraoptic) , Oxytocin (paraventricular)
|
|
|
How are hormones transported from the hypothalamus to the posterior pituitary lobe?
|
oxytocin and ADH is made in the paraventricular n and the supraoptic nucleus.
They travel throught the infundibulum via the hypophyseal tract. oxytocin and ADH are then stored in the axons. Oxytocin and ADH are then released into the blood |
|
|
What is ADH antidiuretic hormone?
|
A hormone that responds to dehydration. targets the kidneys - tighten gap junctions and inserts aquaporins
|
|
|
What can be caused by ADH defieciency?
|
diabetes, excessive urination, thirst
|
|
|
What can be caused by hypersecretion of ADH?
|
meningitis, cancer, water retention, brain edema
|
|
|
What does oxytocin involve?
|
stimulates childbirth uterine contractions (PIP2 Ca)
triggers lactation facilitates sexual arousal |
|
|
What are the hormones released by the anterior pituitary hormones?
|
Growth hormone
thryorid stimulating hormone adrenocorticotopic hormone ACTH Follicle stimulating hormone FSH Luteinizing hormone LH Prolactin PRL all amino dervived all except GH promote cAMP formation |
|
|
What does growth hormone do?
|
stimulates growth
targets bone and skeletal muscle promotes protein synthesis defends blood glucose levels |
|
|
What are the affects of hypersecretion of growth hormone?
|
gigantism, acromegaly
|
|
|
What is the affects of hyoisecretion of growth hormone?
|
dwarfism
|
|
|
What is TSH?
|
thyroid stimulating hormone
|
|
|
What is TSH produced by?
|
a. pituitary
|
|
|
What does THS do?
|
stimulates normal development of thyroid hormone
stimulates normal activity of thyroid hormone |
|
|
What are the functions of T4 and T3 in metabolism?
|
Increases BMR
Breaks down glycogen stores breaks down fat stores protein synthesis |
|
|
What are the functions of T4 and T3 in the Nervous system?
|
normal development in fetus and infant
normal CNS, PNS and ANS increase activity of sympathetic nervous system |
|
|
What are the functions of T4 and T3 in the Nervous system?
|
normal muscular development
normal muscular function normal growth of skeleton |
|
|
Other functions of Thyroid hormone
|
normal functioning of digestive system
normal functioning of reproductive system normal functioning of skin |
