Diencephalon

thalamus and hypothalamus
hypothalamus
- comprised of nuclei responsible for controlling visceral / metabolic activities
- such as water balance, temperature, sleep, metabolic function
thalamus

the principle relay and integration center for sensory information
cerebellum
- coordinates movements that the cerebrum initiates
- ensues precise, smooth, finely tuned movements
striatum

putamen + caudate nucleus
lenticular process
- putamen + globus pallidus
- because their nuclei are lens shaped
Basal Ganglia
function
parts 3
- coordination of fine motor movements
- Parts: caudate nucleus, putamen, globus pallidus
Subcortex contains
- basal ganglia
- (figure 11-20 p. 567)
CNS
sixth lobe
function
- limbic lobe
- not identifiable
- functional relationship with motivation, sex drive, emotional behavior and affect
Insula
portion
involved in

anterior and posterior portions involved in regulation of hormones and homeostasis
Brainstem 3 parts
- Midbrain
- Pons
- Medulla Oblongata
Brainstem
2 functions
damage
- cranial nerves and their nuclei arise fromt he brainstem
- basci bodiy functions for life are maintained here (breathing, swallowing)
- damage to the brainstem can kill someone or make them mbrain dead
