Q

What is the defining feature of thoracic spinal cord in transverse section

A

lateral horn of grey matter

25
where does spinothalamic tract decussate
at the level of spinal cord it enters
26
sensations of spinothalamic tract
crude pain. temperature
27
where is spinothalamic tract
anterior, slightly lateral
28
what is pain sensation called
nociception
29
what is a nociceptor
pain receptor
30
what are the 2 types of spinothalamic receptors
A-delta C
31
where do 2ary spinothalamic neurones go
nucleus proprius to thalamus
32
where do 3ary A delta spinothalamic neurones go
thalamus to primary somatosensory cortex
33
what do A delta fibres feel
fast pain, accurate location and duration of pain, sharp
34
what do C fibres feel
slow pain, lots of activations, intensity=action potentials
35
what are 4 spinothalamic receptor types
thermo- mechano- chemico- polymodal
36
where is the A delta fibres
lateral STT
37
where are the C fibres
anterior STT
38
where is the anterior STT thalamic relay
intralaminar nuclei of thalamus
39
where does 3ary C fibres go (4)
intralaminar nucleus of thalamus to 2ary somatosensory cortex parabrachial nucleus of pons -> limbic system posterior medial nucleus of thalamus -> arousal/focus midbrain reticular formation -> spinal reflexes
40
where does shingles live
sensory dermatomes
41
what is the blood supply to the STT
anterior spinal artery
42
which is the only tract supplied by the anterior spinal artery
STT
43
what are the functions of the DCML
light touch, proprioception, 2 point discrimination, vibration
44
where do you take lumbar puncture
subarachnoid space - csf l4/l5
45
where to you take epidural?
outside dura mater
46
where does DCML decussate
lower medulla
47
what are the decussation fibres of DCML called
internal arcuate
48
what is the DCML tract up to the brain caleld
medial lemniscus
49
what does the D of DCML refer to
DORSAL bit of spinal column
50
what are the two fasciculi of DCML and where do they come from
gracilis, medial, legs/genitalia cuneatus, lateral, arms
51
how do you test DCML proprioception? Name?
can you keep your balance with eyes closed? Romberg's test
52
what is spinocerebellar tract
spine->cerebellum
53
where does spinocerebellar tract decussate
it doesn't
54
what does spinocerebellar tract function
unconscious propriception
55
which important cranial nerve feeds into DCML
trigeminal
56
where does VPM nucleus of the thalamus receive information from
nociception from head and face
57
where does VPL receive information from
nociception from rest of body
58
what is relay from thalamus to 1ary somatosensory cortex part of
internal capsule
59
where have most DCML receptors
fingertips, lips, tongue
