Question

figure 11 - 2 major posterior skeletal muscles
use figure 11 - 2 to answer the following question:
identify the muscle labeled \17.\
extensor carpi ulnaris
brachioradialis
extensor digitorum
pronator teres
anconeus

Explanation:

The extensor carpi ulnaris is a muscle located on the posterior (back) side of the forearm. It is responsible for extending and adducting the wrist. In anatomical diagrams of the posterior skeletal muscles, it is typically labeled in the forearm region. The other options:

• Brachioradialis is located on the lateral (outer) side of the forearm but is more anterior in some aspects compared to the extensor carpi ulnaris in terms of posterior - forearm muscle groupings relevant to this diagram.
• Extensor digitorum is also in the forearm but has a different function (extending the fingers) and a different anatomical location in the muscle group layout.
• Pronator teres is more involved in forearm pronation and has a different location.
• Anconeus is a small muscle near the elbow with a different function (assisting in elbow extension and joint stability).

Answer:

extensor carpi ulnaris
