30
Q

what is in the CNS?

A
  • cerebrum
  • cerebellum
  • brainstem
  • spinal cord
  • pre-ganglionic autonomic neurons
31
Q

what is in he PNS?

A
  • spinal nerves and rami
  • somatic nerves
  • visceral nerves
  • autonomic ganglia and post autonomic neurons
32
Q

what are the parts of the Cerebrum? what is in each part?

A
  1. Telencephalon: Cerebral cortex and subcortical regions

2. Diencephalon: Thalamus and hypothalamus

33
Q

what are the parts of the cerebellum?

A
  • midbrain
  • pons
  • medulla
34
Q

are the lobes of the brain different tissues?

A
  • nope

- they are continuous

35
Q

what are the hollow, empty spaces deep in the hemisphere?

A

ventricles

36
Q

the thalamus and hypothalamus are deep to what?

A

the wall of the third ventricle

37
Q

the brain and spinal cord develop from a fluid filled neural tube filled with what?

A

-originally amniotic fluid, but replaced with CSF

38
Q

what produces the major CNS regions?

A

-growth and folding of the neural tube

39
Q

what is the flow pattern of CSF through ventricular space?

A
  • Choroid plexus secretes CSF by filtering plasma
  • uni direrctional flow through ventricular system
  • CSF exits through small foramen to subarachnoid space
  • CSF reabsorbed into veins and sinuses
40
Q

what is the lateral aperture responsible for?

A

-hydraulic suspension of the brain

41
Q

what is the median aperture responsible for?

A

acts as pore for CSF to go to the outside of the brain
