Q

Why is the grey mater region of the spinal cord significantly larger in the cervical and lumbar regions compared to the thoracic and sacral regions?

A

The cervical and lumbar regions supply the upper and lower limbs respectively so will carry lots of sensory and motor fibres in comparison to the thoracic and sacral regions which innervate the trunk

18
Q

How much CSF is produced each day?

A

500ml

19
Q

What is the function of the CSF?

A

Afford mechanical and immunological protection to the brain

20
Q

The Pia mater consists of a unicellular membrane. T/F?

A

True

21
Q

How is the Pia mater separated from the spinal cord?

A

Sub-pial space

22
Q

The denticulate ligaments are formed from the Pia mater. What is their function?

A

Prevent lateral displacement of the cord

23
Q

What is the clinical significance of the Boston venous plexus of the spinal cord?

A

Major route in the spread of cancer from deep pelvic regions

24
Q

Describe the blood supply to the spinal cord in the cervical and thoracic regions?

A

Anterior spinal artery

2 posterior spinal arteries

25
Q

From which arteries does the anterior spinal artery arise?

A

Intercostal arteries

26
Q

Which artery supplies the lower 1/3 of the spinal cord?

A

Artery of adamkiewicz

27
Q

What are the symptoms of anterior spinal artery syndrome?

A

Loss of urinary and or faecal continence

impaired motor function of the legs/spasticity

28
Q

Where are epidural injections and lumbar punctures taken from?

A

L3/4 or L4/5 junction

29
Q

What are the functions of lumbar puncture?

A

Diagnostic - withdraw CSF or measure CSF pressure

Therapeutic purposes - administration of antibiotics or a route for chemotherapy

30
Q

What is the name of the most caudal point of the spinal cord?

A

Conus medullaris

31
Q

Where does the filum terminale extend from?

A

The tip of the conus medullaris to the sacrum

32
Q

What is the function of the filum terminale?

A

Helps to hold the spinal cord in place

33
Q

Through which types of nerve fibres is painful stimuli transmitted to the dorsal horn?

A

A-delta

C fibres

34
Q

Through which type of nerve fibre is proprioceptive sensory information transmitted to the dorsal horn?

A

A-alpha fibres

35
Q

Mechanoreceptors convey sensory information to the dorsal horn via which type of fibre?

A

A-beta fibres

36
Q

The largest, myelinated fibres transmit nerve signals most slowly. T/F?

A

False - these fibres have the fastest conduction speeds

37
Q

From which horn of the spinal cord do motor fibres leave?

A

Ventral horn

38
Q

What is the name for the layers and columns seen in a transverse section fo the spinal cord?

A

Rexed’s laminae

39
Q

In which columns in the spinal cord are the cell bodies of preganglionic sympathetic fibres found?

A

Interomedial lateral column

40
Q

In which laminae of the grey mater do sensory inputs from the skin terminate?

A

Laminae 1-4

41
Q

Veins in the spinal cord form the internal epidural venous plexuses and pass superiorly through the foramen magnum to drain into…?

A

The dural sinuses

42
Q

What is the name of the layers and columns which divide the grey matter of the spinal cord?

A

Rexed’s laminae
