ENDOCRINE SYSTEM TEST 1
QUESTIONS WITH VERIFIED
ANSWERS
Hypothalamo-Hypophyseal Tract - ANSWER-axons that go from the Hypothalamus
to the Pos. Pituitary gland, all the way to the infundibulum
Where is ADH and Oxytocin produced? - ANSWER-in the hypothalamic neurons
How is the ADH and Oxytocin produced? - ANSWER-packaged into vesicles and
transported to nerve terminal in posterior pituitary where they are stored
True or False? - ANSWER-Pos. Pituitary does not synthesis any hormones of its
own
Pathway of Oxytocin - ANSWER-Hypothalamus--Paraventricular nucleus---tract--
pos. pituitary gland----generates a hormone
Where is the target tissue for ADH? - ANSWER-Kidney tubules
What are some stimulus of ADH? - ANSWER-dehydration increase plasma
osmolarity stimulates the release of ADH
low blood volume also increases the release of ADH
What are the receptors for the ADH? - ANSWER-osmoreceptors
Diabetes Insipidus - ANSWER-Increase ruin output
Tasteless pee
Lack of ADH
Diabetes Melianuius - ANSWER-Increased ruin output
surgary pee
SIADH - ANSWER-Syndrome of Inappropriate ADH release
water retention
high blood volume
increase blood pressure
Oxytocin - ANSWER-released from the pos. pituitary gland not created there
causes uterus to contract
nursing allows oxytocin to be release so that the milk will move down so the baby
can feed
Non-pregnant uterus will not have oxytocin receptors
When contraction starts your oxytocin receptors are up regulated
Anterior Pituitary, the axons don't extend to where? - ANSWER-Axons do not extend
to the infundibulum
, What and where is the hypophyseal portal system - ANSWER-Special arrangement
of blood vessels
Capillary vein capillary
network, venule, network
Hypothalamic Hormone - ANSWER-Corticotropin RH
Thyropropin RH
Growth Hormone RH
Growth Hormone IH
Somatostatin
Conadotropin RH
Prolactin IH
Anterior Pituitary Hormone - ANSWER-Adrenocoprticotropic H (ACTH)
Thyroid Stimulating Hormone (TSH)
Growth hormone
Follicle Stimulating Hormone
Leutinizing Hormone
PRL
Cells of the anterior Pituitary - ANSWER-somatotrpes
Mammotropes
Gonadotropes
Thyrotopes
Corticotropes
-can have tumors of only one of these cells types
this can cause an over secretion of a hormone
-if the tumor is too big it can press on neighboring cells and shut off production of
those hormones
Somatotropes - ANSWER-GH
Mamotropes - ANSWER-lactotropes; Prolactin
Gonadotropes - ANSWER-FSH
LH
Thyrotropes - ANSWER-TSH
Corticotropes - ANSWER-ACTH
Growth Hormone 1/2 Life - ANSWER-Really Short 1/2 Life
6-20 Mins
What happens with the GH acts on the liver? - ANSWER-the liver will release IGF
What is IGF? - ANSWER-Insulin Growth Factor
1/2 life of IGF - ANSWER-1/2 life of about 20 hours
