Q

What happens to a damage to one spinal segment or root?

A

Cannot completely paralyze any limb muscles because each receives nerve supply from more than one spinal nerve (because of nerve plexuses).

A

Obturator nerve, located in medial thigh

30
Q

What does the femoral nerve of the lumbar plexus do and where is it located?

A

Femoral nerve is a thigh flexor & knee extensor because it is located at the anterior thigh muscles.

31

Q

What is the map of the body that allows doctors and surgeons to local the nerve or injury?

A

Dermatome

35
Q

Associate the wrappings of nerves.

A
  1. Endoneurium: encloses nerve fiber (myelin or neurilemma sheath)
  2. Perineurium: around group of fibers (fascicle)
  3. Epineurium: around fascicle to make nerve
36
Q

how can the sensory receptors be classified as?

Lists the different types of sensory receptors according to location.

A
  • Exteroceptors (outside + special senses)
