Dua Mater
Arachnoid Mater
Dura Mater

32
Q

What is found in the subarachnoid space?

A

Cerebrospinal fluid.

33

A

Extension and flexion of leaning forwards and backwards.
Rotaion of head and neck.
Rotation of upper trunk.
Lateral flexion and extension of the neck.

34

37
Q

What number of vertebrae is the axis?

A

C2

38
Q

what type of joint is the intervertebral discs?

A

Symphysis

39
Q

What type of joint are the facet joints?

A

Synovial plane

40
Q

What type of joint are the joints in ribs?

A

Synovial

41
Q

What kind of joints are the skull and axis?

A

Synovial ellipsoid

42
Q

What kind of joints are the atlas and axis?

A

Synovial pivot

43
Q

From the side, what do cervical vertebraes look like?

A

\

44
Q

From the side, what do thoracic vertebrae’s look like?

A

I
Parallel

45
Q

A

\ /

46
Q

What region is good for flexion and extension?

A

Lumbar

47
Q

Name the ligaments of the vertebral column.

A

Anteriior longitudl-
Posterior longitudinal-
Interspinous ligament
Supraspinous ligaments
Ligamentum flvum- prevents vertebrae getting pulled apart

48
Q

What can the anterior longitudinal prevent?

A

Prevents hyperextension as at the front of the spine

49
Q

What can the osterior longitudinal prevent?

A

Prevents hyperflexion.

50
Q

What are the intrinsic muscles?

A

Muscles which only act on the back

51
Q

What are erector spinae?

A

Intrinisc back muscles which assits with extrension mainly, but also lateral flexion and ‘controlling’ flexion.

help with flexion but do not write this as an answer as the main function is extension!!!

52
Q

Where do extrinsic back muscles extend to?

A

Head
Limbs
Thorax
Abdomen

53
Q

Give an example of controlling flexion

A

Bowing

54
Q

Where are erector spinae?

A

Posterior to the spinal cord

55
Q

Where are intrinsic back muscles found?

A

Anterior to the spinal cord

56
Q

What structure is found right next to the spine?

A

Sympathtic trunk.

57
Q

What is found in the sympathetic trunk?

A

Sympathetic ganglia

58
Q

Where are para and pre vertebral ganglia found

A

In front of the spine idk look it up pls soz bestie

59
Q

what can happen to the vertebral column due to aging?

A

-Weakness of back muscles
-Osteoartiritis
-Osteoporosis

60
Q

What can weakness of back muscls lead to?

A

Imbalanced loading of the spine
Back pain.

61
Q

What can osteoarthritis lead to?

A

Paiin and stiffness of joints

62
Q

What can osteoporosis lead to?

A

Compression fractures altering the curvature of the spine.

63
Q

Describe the movement that the cervical region of the vertebral column gives rise to.

A

All movement

64
Q

Describe the movement that the thoracic region of the vertebral column gives rise to.

A

Rotation
Slight flexion/extension

65
Q

Describe the movement that the lumbar region of the vertebral column gives rise to.

A

Flexion and extension
Slight rotation

66
Q

Which part of the vertebral column supports the weight of the upper body?

A

Lumbar

67
Q

Which part of the lumbar section does a lumbar puncture take place

A

L3-4

68
Q

Why does a lumbar puncture take place at L3-4?

A

Spinous processes are furthest apart so it is easier to get the needle into the subarachnoid space.

69
Q

What kind of joint is found between ribs?

A

Synovial plane joints

70
Q

At what level of the vertebra is the inferior angle of the scapula?

A

T7

71

A

Arm

72
Q

Where does the ulnar artery arise?

A

Level of the radial neck

73
Q

What are the two branches of the brachial artery?

A

Radial artery and ulnar artery
