CNS Division Functions

Question 1

medulla

Answer 1

lateral reticular nuclei –> respiratory and blood pressure control, decussation of coricospical tracts (pyramids)

Question 2

mesencephalon

Answer 2

5/6 EOM supplied, inferior colliculus (auditory), superior colliculus (visual), red nucleus (motor correction), vertical eye movement

Question 3

parts of the mesencephalon

Answer 3

basis pedunculi: substantia nigra & crus cerebri
tegmentum: tracts, decussation of the superior cerebellar peduncle
tectum: superior & inferior colliculus

Question 4

pons

Answer 4

motor operation of face, jaw, and EOM (abduct), motor impulses from cerebral cortex synapse and sent to cerebellum, horizontal eye movement

Question 5

diencephalon

Answer 5

Relays sensory and motor signals to cerebral cortex and regulates the body’s systems, houses lateral geniculate nucleus

Question 6

thalamus

Answer 6

Relay center for sensory and motor pathways

Question 7

hypothalamus

Answer 7

regulation

Question 8

epithalamus

Answer 8

emotional & vegetative functions

Question 9

telencephalon

Answer 9

controls almost all voluntary movements in the body, as well as language, speech, learning, memory, and sensory processing.

contains basal ganglia, which control motor

Question 10

cerebellum

Answer 10

receives info from periphery and cerebral cortex.

responsible for coordinating movement, balance, and posture. Also help fine-tune motor activity

Question 11

corticopontine fibers

Answer 11

synapse on pontine and project to contralateral cerebellar hemisphere via pontocerebellar fibers
