What is the proximal attachment of most of the forearm flexors?

Medial Epicondyle

A patient is asked to flex the distal interphalangeal joint of the 2nd digit while the

physiotherapist holds the digit’s proximal interphalangeal and

metacarpophalangeal joints in extension. What muscle is being tested by this

flexion action

Flexor Digitorum Profundus

What movement is created by pronator teres

Pronation of forearm

What movement is caused by pronator quadratus

Pronation of forearm

What muscles would cause flexion at the wrist joint

Flexor carpi radialis and ulnaris Palmaris Longus

The precision grip is used to hold small objects between the pads of the digits. It

involves small muscles of the hand that you will study in the next session but also

some of the muscles you have identified in this station. Which of the muscles you

have studied in this station are likely to be involved in a precision grip
