Origin, middle third of posterior surface of tibia;insertion, by four tendons, perforating those of the flexor brevis, into bases of distal phalanges of four lateral toes;action, flexes second to fifth toes;nerve supply, tibial nerve.
2. A contractile organ consisting of a special bundle of muscle tissue, which moves a particular bone, part, or substance of the body: the heart muscle; the muscles of the arm. 3. Muscular strength: enough muscle to be a high jumper. 4. Informal Power or authority: put some muscle int...
During the laboratory dissection of the fore arm, an accessory head of flexor pollicis longus muscle has been observed unilaterally in the right upper limb of a male cadaver. It took its origin from the under surface of flexor digitorum superficialis muscle just distal to the origin of this ...
It is absent in primates such as gorilla and chimpanzee in whom a well- developed flexor hallucis longus perform the same function as that of flexor pollicis longus performs in man1. The FPL chiefly arises from the anterior surface of the shaft of the radius intervening between radial ...
The flexor pollicis longus (FPL) is a long, fast-acting, skeletal muscle in the deep layer of the anterior compartment of the forearm; it is the extrinsic flexor of the pollex (digit #1). Its proximal attachment is to the anterior surface of the proximal radius and interosseous membrane, ...
The metabolic response to graded rhythmic forearm exercise determined by nuclear magnetic resonance (-NMR) spectroscopy was evaluated with respect to recruitment pattern of muscles and to fiber type composition of the nondominant arm in 14 untrained subjects. Rectified smoothed surface electromyography (rs...
After crossing the palmar side of the wrist within the carpal tunnel, each tendon attaches to the palmar surface of a particular phalanx. The tendons of the flexor digitorum superficialis attach to the base of the middle phalanx; the deeper tendons of the flexor digitorum profundus continue dist...
Forearm muscle. Origin: coronoid process of ulna, anterior surface of radius. Insertion: distal phalanx of thumb. Nerve: median (C8-T1). Action: flexes thumb. See:armfor illus. (Muscles of the Arm) See also:muscle Medical Dictionary, © 2009 Farlex and Partners ...
Origin, by two heads from the lateral and medial borders of the inferior surface of the calcaneus; insertion, tendons of flexor digitorum longus; action, assists long flexor; nerve supply, lateral plantar. Synonym(s): musculus quadratus plantae [TA] . Medical Dictionary for the Health Profes...
The sensory nerves from the digits of the pelvic limbs are primarily branches of the sciatic nerve, the superficial peroneal nerve on the dorsal surface, and the tibial nerve on the plantar surface. The sciatic nerve originates from spinal cord segments L6-S1. The medial digit is partially ...
