Neuro Anatomy Flashcards
1
Q
CNS
A
- Brain: stem, cerebellum, thalamus, basal ganglia, cerebral cortex
- Spinal Cord
2
Q
PNS
A
- cranial nerves
- spinal nerves
- autonomic nervous system (invol): sympathetic (norep), parasympathetic (acetylcho), enteric nervous system (GI fx)
3
Q
PNS Dorsal Root
A
afferent sensory (input)
4
Q
PNS Ventral Root
A
efferent motor (output)
5
Q
EPSP
A
excitatory postsynaptic potential
“likely to fire”
6
Q
IPSP
A
inhibitory postsynaptic potential
“less likely to fire”
7
Q
Glial Cells
A
PNS: schwann cells, satellite cells
CNS: oligodendrocytes, astrocytes, ependymal cells, microglial
8
Q
Schwann Cells
A
PNS
produce myelin
9
Q
Satellite Cells
A
PNS
support function + structure of cell body
10
Q
Oligodendrocytes
A
CNS
produce myelin
11
Q
Astrocytes
A
CNS
nutrition
supple cells of blood brain barrier
maintain extracellular ion balance
recycle neurotransmitters
release “gliotransmitter” influence
release of glutamate
12
Q
Ependymal Cells
A
CNS
line ventricles
produces CSF
13
Q
Microglial Cells
A
CNS
protect brain illness + disease
14
Q
Neurotransmitter Function
A
- rapid communication - trigger action potential + post synaptic neuron
- neuromodulation - influencing groups of neurons
15
Q
Glutamate
A
excitatory (CNS)
