Neuroanatomy Flashcards
1
Q
ependymal cells
A
canals of the CNS
-cerebrospinal fluid production
2
Q
glial cells
A
- supportive cells
- conduct electrical impulses
- surround neurons and insulate them
3
Q
oligodendroglial cells
A
myelination of axons, local nutrient support
4
Q
astrocytes
A
structural and enzymatic barrier between the nervous sytem and rest of the body
5
Q
microglial cells
A
defence system of the nervous system
6
Q
somatic nerves
A
- locomotor function’
- voluntary
- spinal nerves
7
Q
visceral nerves
A
regulation of internal function
- involuntary
- autonomic
8
Q
Afferent nerve fibres
A
arrive at a particular brain region
9
Q
Efferent nerve fibres
A
exit a particular brain region
10
Q
Brainstem
A
consciousness, cardiovascular system and breathing
11
Q
cerebellum
A
coordinates movement
12
Q
CNS-meninges
A
dura, arachnoid, pia
13
Q
cerebrospinal fluid
A
cushioning maintains fluid balance nutrition movement of neurotransmitters reg.of respiration
14
Q
Spinal cord ascending signals
A
- harmful stimuli
- perception of pain
- nociceptors(pain receptors)
- detec changes
- skin, periosteum, joint surface
15
Q
spinal cord descending signals
A
motor tracts and neurons
