week 9 Flashcards

1
Q

Branches of the Spinal nerve

A

Dorsal ramus is distributed to the muscles of the back, and the skin covering those muscles
* Ventral ramus is distributed to the muscles of the anterior and lateral trunk, and the corresponding skin
* Ventral rami are also distributed into the limbs to supply the muscles and skin there

19
Q

what are the most venerable sites of Damage to Peripheral Nerves

A
  • Close to skin - penetrating injury
  • Between skin and bony projection - crushing injury e.g. plaster applied to tightly
  • Between retinacula and bone - squashing injury or small amount of swelling with no where to go
  • On bone - from fracture
20
Q

what are the common effects of nerve lesions

A
  • Paralysis / paresis
  • Loss of sensation
  • Seen distal to lesion
21
Q

sensory loss: Loss of skin sensation on the medial and anterior thigh, medial leg and medial foot
Functional motor loss
