25
cauda equina is what nerve roots
L2-Co
26
Posterior rami of the sacral sinal nerves exit where
the posterior sacral foraminae
27
which herniation is most common for causing an oculomotor palsy
Uncal herniation - will therefore lead to an ipsilateral fixed dilated pupil
28
Multipolar found where
Skeletal muscle and ans
29
where is the cell body of the multipolar neurone found
CNS
30
neurone in the PNS
unipolar
31
collection of nerve axons and bundles in CNS are called
tracts
32
do sympathetics supply arterioles
yes - the smooth muscle of arterioles
33
posterior scalp, neck and shoulder dermatomes
C2-4
34
sympathetics exit where on the spinal cord
T1-L2 lateral horns
35
Parasympathetic outflow
3 7 9 10 and sacral
36
extrinsic back muscles
trap and lat
37
intrinsic back muscles
erector spinae and transversospinalis
38
transversospinalis is located where
between the transverse and spinous processes
39
nerve supply of the intrinsic back muscles
segmental and via posterior rami
40
roles of intrinsics
posture, support and extend | - if erector spinae contracts unilaterally, it allows for lateral flexion
41
flexion of the spine aided by
psoas major and rectus abdominis
42
the superior and inferior articular processes have what type of join
synovial facet joint - this allows for mobility between adjacent vertebrae
43
is there an intervertebral disc between C1 and c2
NO - fused at sacrum/coccyx
44
anterior longitudinal ligament stops what
over-extension
45
posterior longitudinal ligament stops what
over-flexion
46
What to ligaments can be found between the spinous processes
supraspinous (stong, fibrous, connects spinous tips)and interspinous (connects superior and inferior surfaces)
47
cervical vertebrae have what common characteristics
bifid transverse foramen triangular shaped vertebral foramen
48
which one has the atlas
C1 - At the first one doesn't have a body or a spinous process - instead has a posterior and anterior arch
49
which one has an axis
C2 - next after AT las | has an odontoid process and projects superiorly
50
first palpable vertebrae 1
C7
51
Atlanto-occipital joints
synovial joints | between occipital and the superior articular facets
52
what is the point bit seen on X ray of the c1 cervical spine
the posterior arch of the atlas
53
cauda equina and meninges can be found where in the sacrum
the sacral canal
54
where do nerves exit/enter in the sacrum
through ant and post sacral foraminae
55
where does caudal anaesthesia take place
into sacral hiatus to anaesthetise the sacral spinal nerve roots
56
spinal cord ends
L1/2
57
Cauda equina involves which nerve roots
L2-CO
58
T12 names nerve
subcostal
59
names nerve contains only one spinal nerve?
no - contains multiple axons from diff spinal nerves which are travelling to a similar location eg msc C5,6,7
60
Femoral nerve roots
L2-4 | means that it crosses multiple dermatomes
61
C1-C4 supplies
neck postural and strap muscles | diaphragm
62
brachial plexus supplies
upper limb and extrinsic back muscles
63
T2-L3 motor axons supple
via posterior rami the postural back mucles intercostal muscles via anterior rami anterolateral abdominal wall muscles
64
lumbosacral nerve roots
L1-S4
65
Triceps jerk
C7
66
Brachioradialis
C6
67
Biceps rachii
C5.6
68
Knee jerk
L3
69
ankle reflex
S1
70
Axillary supplies
5,6 | deltoid and teres
71
thenar and lumbricals 1 and 2
median
72
7,8,T1
ulnar
73
supply of the dorsal and plamar interossie and hypothenar
ulnar
74
Sciatic
L4-S3
75
whic CNs are located at the pontomedullary junction
6,7,8
76
left recurrent
under arch of the aorta
77
right recurrent laryngeal
right subclavian
78
bartholins gland in females is otherwise known as what in males
bulbourethral
79
superior sagittal sinus can be found
falx cerebri location
80
the confluence of the sinuses?
in the midline at the internal occipital protruberance, which is deep to the external occipital protruberance
81
wich sinus drains into the IJV
the sigmoid sinus
82
the vertebral arteries are branches from what artery
the right and left subclavian
83
the circle of willis can be found in what meningeal layer
SAS | closely related to the optic chiasm
