Final answer:
The flexors of the hand are located on the anterior part of the forearm, enabling finger flexion and wrist flexion. The extensors are found on the posterior part of the forearm, allowing for finger extension and wrist extension.
Step-by-step explanation:
The flexors of the hand are located on the anterior part of the forearm, whereas the extensors of the hand are located on the posterior part of the forearm. Flexors such as the flexor digitorum superficialis and flexor digitorum profundus are responsible for the flexing movement, which brings the fingers closer to the palm and the palm towards the wrist, and they are located in the anterior compartment of the forearm. On the other hand, extensors like the extensor digitorum enable the extension of the fingers and the hand at the wrist, and they are seated in the posterior compartment. Muscles like biceps brachii, brachialis, and brachioradialis also contribute to forearm flexion, while muscles such as the triceps brachii and anconeus are among the extensors. The specific tendons of these muscles attach to the wrist and extend into the hand, with fibrous bands called retinacula sheathing these tendons at the wrist; the flexor retinaculum is on the palmar surface while the extensor retinaculum is on the dorsal surface.
