|
-surrounds the third ventricle
-Thalamus, hypothalamus, and epithalamus |
|
|
What is the thalamus and what is its function?
|
-major part of diencephalon
-primary relay center for all sensory impulses except olfaction (smell) -directs impulses to correct part of cerebral cortex -if too many impulses at once, decides to go into shock |
|
|
What does the hypothalamus do and contain?
|
-monitors blood, nervous system, and endocrine system
-regulates body temperature -emotional behavior -controls food/water intake -causes sleep-wake syndrome (biological clock) -runs pituitary gland -houses mammilary bodies |
|
|
What is the pituitary gland and what does it porduce?
|
-"master gland"
-produces hormones |
|
|
What do mammillary bodies do?
|
-controls olfactory reflexes (sniff, sneeze)
-controls taste reflexes (salivation) |
|
|
What is part of the epithalimus?
|
-pineal gland

|
|
|

|
|
What are the superior colliculi used for?
|
-used for hand-eye coordination (visual reflexes)
|
|
|
What are the inferior colliculi used for?
|
-used for auditory reflexes
