Injuries of Nerves (brachial + lumbosacral) Flashcards
Primary motor of musculocutaneous branch
Flexion of the elbow, supination of forearm
Primary motor of ulnar branch
Some wrist and finger flexion
Hand muscles
Primary motor of medial branch
most wrist and finger flexion
pronation of the forearm Thenar muscles
forearm Thenar muscles
palmar muscles controlling the thumb
primary motor of radial branch
Extension! Of arm, forearm, hand
Supination of forearm
primary motor of axillary branch
abduction, flexion, extension and lateral rotation of upper limb
primary motor of genitofemoral nerve
cremaster muscle
primary motor of femoral nerve
hip flexion
knee extension
primary motor of obturator
leg adduction
primary motor of superior / inferior gluteal
extension, abduction, lateral rotation of thigh
primary motor of Sciatic - tibial
Hip extension, most knee flexion, all plantar flexion of the foot
primary motor of Sciatic - common fibular
Some knee flexion, all dorsiflexion and eversion of the foot
what happens if you injury femoral nerve?
cannot extend the knee
injury to musculocutaneous
weakness in flexion of elbow / shoulder
not able to supinate forearm
injury to axillary
shoulder weakness
