Which muscles are bound by the extensor retinaculum?

The superior extensor retinaculum binds down the tendons of extensor digitorum longus, extensor hallucis longus, peroneus tertius, and tibialis anterior as they descend on the front of the tibia and fibula; under it are found also the anterior tibial vessels and deep peroneal nerve.

Where is flexor digitorum Superficialis?

Is bicep a flexor or extensor?

Contracting your biceps exhibits flexion, i.e. it brings your forearm closer to your upper arm and decreasing the angle between the two. So, your biceps is described as a “flexor” muscle. The opposing muscle of a flexor is called the “extensor” muscle. Your triceps is an extensor.

What is extensor retinaculum attached to?

The extensor retinaculum is attached laterally to the lateral margin of the radius. However, it is not attached to the ulna, as the distance between these two bones varies with supination and pronation of the forearm.

What are hand intrinsics?

The intrinsic group are the smaller muscles located within the hand itself. The muscles of the hand are innervated by the radial, median, and ulnar nerves from the brachial plexus.
