Q

whats touch receptor called

A

Meissners corpuscle

18
Q

whats pressure receptor called

A

paccinian corpuscle

19
Q

what does free nerve ending affect

A

unmyelinated for pain and temp`

20
Q

what is the 3 regions of grey matter

A

sensory, autonomic, motor

21
Q

whats autonomic for

A

balance and posture

22
Q

what carries discriminative info

A

dorsal funiculus

23
Q

where do pain and temp fibres transport up to

A

ventral funiculus

24
Q

whats brown sequard syndrome

A

where one side of the spinal cord is damaged

25
whats dissociative and associative sensory loss
dissociative - lesion further up associative -lesion in brain stem
26
what does lesion in upper motor neuron cause
spastic paralysis
27
lesion in lower motor neuron causes
flaccid paralysis
28
what are pyramids associated with
corticospinal tract
29
what causes parkinsons disease
destruction of cells in substantia niagra (needs more glutamate but its toxic)
30
What’s white matter
Has axon Tracts coming out from neurons
31
What’s grey matter
Where neuron cell bodies are housed
32
What’s Meissners corpuscle
Touch encapsulated receptor
33
What’s paccinian corpuscle
Pressure encapsulated receptor
34
What does less neurons mean
Less pain or sensation in that area
35
What sorts out what information is important and relevant at the time
Thalamus
36
where does pathway of discriminative sensation occur
dorsal medial lemniscal (cross over occurd at brain stem medulla)
37
where does pathway of pain/temp sensation occur
spinothalamic tract (crosses over in spinal cord)
38
where does discriminative info decussate
internal arcuate fibres
39
what are the 5 basal ganglia
caudate nucleus putamen globus pallidus subthalamic nucleus substantia nigra
