Front 25

Plantar flexion

Back 25

What does the flexor hallicus longus muscle do?

A patient is unable to flex the hip or extend the leg due to paralysis of the quadriceps femoris. Which nerve is damaged?

Front 27

Obturator Nerve

Back 27

A patient has weakness upon adduction and a lateral swinging of the limb during walking because of the unopposed abductors. Where is the lesion?

Front 28

Sciatic nerve

Back 28

A patient has impaired extension at the hip and impaired flexion at the knee, loss of dorsiflexion at the ankle and of eversion of the foot, and a PECULIAR GAIT because of increased flexion at the hip to lift the dropped foot off the ground.

Front 29

Common peroneal nerve

Back 29
