19
Q

What meningeal space does a lumbar puncture take place?

A

Subarachnoid Space

20
Q

What meningeal space is an epidural provided

A

Epidural Space

21
Q

Where is CSF fluid found

A

Subarachnoid space

22
Q

Function of the CSF

A

Cushion for CNS and nourishes the brain and spinal cord

23
Q

What is the function of the denticulate ligament

A

Supports the spinal cord and holds pia mater in place

24
Q

Name all the divisions of the PNS

A
25
Q

Name all the missing parts of the spinal cord

A
26
Q

White Matter is [myelinated /unmyelinated]

A

Myelinated

27
Q

Grey matter is [myelinated/unmyelinated]

A

unmyelinated

28
Q

Ventral is [sensory/motor]

A

motor

29
Q

Dorsal is [sensory/motor]

A

sensory

30
Q

Voluntary Muscle innervation pathway…

A

1) Ventral horn of spinal cord
2) ventral root
3) spinal nerve
4) ventral or dorsal ramus
5) muscle

30
Q

Sensory innervation pathway…

A
  1. Sensory receptor
  2. Ventral or dorsal ramus
  3. Spinal nerve
  4. Dorsal root ganglion
  5. Dorsal root
  6. Dorsal horn of spinal cord
31
Q

Name what happens at each impairment

A

1) Spinal nerve -> loss of sensory and motor information
2) Dorsal root -> loss of sensory information
3) Ventral horn of spinal cord -> Loss of motor information

32
Q
A

Dorsal ramus because they are only having motor problems with dorsal and not ventral areas of body Ventral refers to front of body and dorsal refers to back of body
