Flexors of the forearm

Learning objectives:

This comprehensive study unit will help you to:

  1. Identify the flexors of the forearm and how they are arranged into groups.
  2. Learn the attachments and innervation of these muscles.
  3. Become familiar with the function of each muscle.

Watch video

Flexors of the forearm occupy the anterior compartment of this region. Based on their location in the compartment, they are divided into two groups:

  • Superficial flexors of the forearm
  • Deep flexors of the forearm

These muscles act on different joints of the upper limb, enabling movements of the forearm, hand and fingers. All muscles are innervated by the branches of the brachial plexus, mainly the median nerve. The exceptions are the flexor carpi ulnaris, which is supplied by the ulnar nerve, and the flexor digitorum profundus, which is innervated by branches of both the median and the ulnar nerves.

The following video tutorials will help you learn the anatomy of the flexors of the forearm.
