Origin, base of metatarsal bone of the little toe and sheath of musculus peroneus longus;insertion, lateral surface of base of proximal phalanx of little toe;action, flexes the proximal phalanx of the little toe;nerve supply, lateral plantar. ...
Rubber bands run from the tips of the injured fingers under a spring-loaded roller bar at the metacarpophalangeal joint level to a coiled lever at the distal flexor surface of the forearm. The wrist is positioned in 45 degrees of flexion with 40 degrees to full flexion of the metacarpo...
supinator - a muscle (especially in the forearm) that produces or assists in supination levator - a muscle that serves to lift some body part (as the eyelid or lip) antagonistic muscle - (physiology) a muscle that opposes the action of another; "the biceps and triceps are antagonistic mus...

11、For example, a longitudinal incision on the flexor or extensor surface of a joint may cause a large unsightly scar or een a keloid that may permanently restrict motion. ─── 例如在关节屈面或伸面的纵行切口可导致难看的大疤痕甚至疤痕疙瘩,引起永久性关节活动受限。 12、Paretic in, enjoin ...
In the lower third of the forearm, it gives off a long tendon that passes below the flexor retinaculum into the palmar surface of the hand. Within the flexor retinacular space, the tendon passes through its own synovial sheath. It then crosses the palmar surface of the scaphoid bone and ...
example, a sphincter, results in constriction or closure of the opening that the muscle surrounds. A radial muscle, on the other hand, widens the opening when it contracts. The contraction of muscles that are located between bony prominences and the skin changes the shape of the skin surface...
During routine cadaveric dissection of the volar surface of the forearm of a South Indian female of 65 years, we came across a variant of occasional/accessory head of the flexor pollicis longus muscle. It was seen bilaterally arising from the deep surface of the flexor digitorum superficialis. ...
By contrast, the flexor surface isthe skin on the side of a joint that folds. Directed by a flexor muscle, the flexor surface can be described as areas where folded skin can touch, such as the inside of the elbow or the back of the knee. ...
The extensor tendons of the forearm pass through fibro-osseous tunnels on the dorsum of the wrist. These tunnels, which are lined with a synovial sheath, are bounded superficially by the extensor retinaculum and on the deep surface by the carpal bones and ligaments. A depression over the dorsol...
