The movements permitted in the metatarsophalangeal joints are flexion, extension, abduction, adduction and circumduction. Left: toes adducted (pulled towards the center) and spread (a b ducted); right, both feet clenched (plantar flexed)
The only movements permitted in the joints of the digits are flexion and extension; these movements are more extensive between the first and second phalanges than between the second and third. The flexor hallucis longus and flexor digitorum longus flex the interphalangeal joint of the big toe and lateral four toes, respectively. The tendons of ...
Range of motion (or ROM) is the linear or angular distance that a moving object may normally travel while properly attached to another. In biomechanics and strength training , ROM refers to the angular distance and direction a joint can move between the flexed position and the extended position. [ 1 ]
In anatomy, extension is a movement of a joint that increases the angle between two bones or body surfaces at a joint. Extension usually results in straightening of the bones or body surfaces involved. For example, extension is produced by extending the flexed (bent) elbow. Straightening of the arm would require extension at the elbow joint.

The flexor hallucis longus is situated on the fibular side of the leg. It arises from the inferior two-thirds of the posterior surface of the body of the fibula, with the exception of 2.5 cm at its lowest part; from the lower part of the interosseous membrane; from an intermuscular septum between it and the peroneus muscles, laterally, and from the fascia covering the tibialis posterior, medially.
Extension is the opposite of flexion, a straightening movement that increases the angle between body parts. [12] For example, when standing up, the knees are extended. When a joint can move forward and backward, such as the neck and trunk, extension is movement in the posterior direction. [ 10 ]
The abductor hallucis as seen from an inferior projection of the foot. This diagram shows the bottom-most layer of muscles, just under the plantar skin of the foot. The abductor hallucis muscle is located in the medial border of the foot and contributes to form the prominence that is observed on the region.
