corpus callosum

18
Q

what is the corpus callosum made of

A

white matter

myelinated axons

19
Q

what is the spinal cord

A

midbrain, pons, medulla

basic functions like heartbeat

21
Q

what are brain ventricles

A

bags full of cerebrospinal fluid

22
Q

what is CSF produced by

A

ependymal cells

23
Q

function of brain ventricles - 3

A

shock absorbers

nutrient supply

waste flush

24
Q

where is the thalamus

A

on top of brainstem region

25
role of thalamus
sensory filtering - advanced - whats not relevant to know rn, important stuff sent to cortex
26
__ are electral signals that travel within neurons
action potentials
27
__ are chemical signals that travel between neurons
neurotransmitters
28
excitatory neurotransmitters like __ inc probablility that a postsynaptic neuron will fire an action potential
glutamate
29
inhibitory neurotransmitters like __ inc probablility that a postsynaptic neuron will fire an action potential
GABA
30
myelin sheath formed of specialist ___ cells, found in ___
shwann peripheral ns
31
myelin sheath in central nervous system formed of specialist ___
oligodendocytes
32
myelin sheath function
electrical insulation, allows faster travel
33
myelin sheaths are found in ___ matter
white
34
lateral sulcus
also called sylvian fissure, separates temporal
