Where is the flexor digitorum?
Flexor digitorum profundus is a fusiform muscle located deep within the anterior (flexor) compartment of the forearm. Along with the flexor pollicis longus and pronator quadratus muscles, it comprises the deep flexor compartment of the forearm.
What is the extensor digitorum?
The extensor digitorum communis is a superficial extensor muscle located in the posterior compartment of the forearm. It shares a common synovial tendon sheaths along with other extensor muscles which helps to reduce friction between the tendon and the surrounding structures.
Where is the hallucis longus tendon?
The flexor hallucis longus is a muscle arising in the calf. Its tendon passes behind the medial malleolus of the ankle, and enters the sole in its medial side. It lies in the bony groove on the inferior surface of sustentaculum tali of the calcaneus as it enters the sole (see Fig. 1.2b).

Is the peroneus longus a flexor or extensor?
The peroneus longus and brevis muscles plantarflex the foot, in conjunction with the tibialis posterior, antagonizing the tibialis anterior and peroneus tertius, which are dorsiflexors of the foot.
What Innervates peroneus longus?
The superficial peroneal nerve supplies motor innervation to the following muscles: Peroneus longus muscle.

What are flexors?
flexor muscle, any of the muscles that decrease the angle between bones on two sides of a joint, as in bending the elbow or knee. … The flexor digitorum profundus is a deep muscle that originates at the ulna (bone of the forearm) and acts to bend the fingers near their tips.
Where does flexor hallucis brevis insert?
Purpose of the study: The flexor hallucis brevis (FHB) is one of the short muscles of the foot. It divides in front into two portions, which are inserted into the medial and lateral sides of the base of the first phalanx of the great toe.

What is flexor pollicis longus?
The flexor pollicis longus (FPL) is a long muscle located at the deep layer with flexor digitorum profundus and pronator quadratus in the anterior compartment of the forearm. Though it is situated at the forearm, it is classified as part of the extrinsic muscles of the hand as it’s function is seen in thumb movement.
