Compartments of the Forearm and Extensor Mechanism

The anterior (flexor) compartment of the forearm is innervated primarily by the (a)   nerve.

The posterior (extensor) compartment of the forearm is exclusively innervated by the (a)   nerve and its branches.

(a)   is a muscle that is part of the Mobile Wad.

Which muscle is part of the Mobile Wad?

(a)   is a muscle that is part of the Mobile Wad.

The Mobile Wad is innervated by the (a)   nerve.

The muscle in the superficial layer responsible for wrist flexion and radial deviation is (a)   .

Which muscle in the superficial layer is sometimes congenitally absent and is responsible for wrist flexion?

(a)  

The function of the flexor digitorum superficialis in the intermediate layer of the anterior compartment is flexion of the (a)   phalanges of digits 2-5.

The flexor digitorum superficialis has a unique split tendon design to allow deeper tendons to pass through.
