Endo Quiz 4- Questions with Correct Answers
1. Diencephalon gives rise to the thalamus, hypothalamus, and epithalamus
2. Thalamus relays messages between lower brain centers and cerebral cortex for most CNS
info
3. Hypothalamus - center for behavioral drives; influences autonomic n.s. functions, and endocrine
functions
4. Pituitary - posterior: neuroendocrine functions
- anterior: true endocrine functions
5. pineal gland - neuroendocrine functions; secretes melatonin
6. What are "true" - epithelium
endocrine struc-
tures made of?
7. Nucleus (brain) - cluster of neuron cell bodies
8. hypothalamic nu- - clusters of neuron cell bodies that make up the hypothalamus
clei
9. Pituitary experi- 1.removed pituitary: organ atrophy
ments by Harris 2.ectopic transplant: similar organ atrophy
and Jacobson 3.retransplant: revascularization and functional reactivation of the pituitary
4.barrier in infundibulum: organ atrophy
10. neurovascular - Humoral factors from the hypothalamus are carried by blood vessels to pituitary
hypothesis regulate hormone secretion
- Hypothalamic extracts stimulate or inhibit secretion from the pituitary
11. post. pituitary re- - neuron cells in the hypothalamus produce oxytocin and vasopressin
