Evaluation of Muscle Function of the Extensor Digitorum Longus Muscle Ex vivo and Tibialis Anterior Muscle In situ in Mice
Published on: February 9, 2013
Abstract:
An alternate procedure to lengthen the long extensor tendons has been examined. Thirty-six separate cases, of which 22 were bilateral, were performed during a 2-year period. The operations were performed both with percutaneous and traditional exposed approaches. The procedures consisted of lengthening by simple tenotomy, Z-plasty, or tendon-slide of the extensor digitorum longus and peroneus tertius at the ankle level. Most were done as an adjunct to biomechanical treatment or osseous operations with a few of the procedures utilized as the sole mode of therapy. Although it was found that the ease of technique and accessibility of tissues made the procedures desirable, the extended postoperative period and efficacy for other than minimal contractures seemed to out-weigh the advantages. The conclusion is drawn that the extensor release at the level of the ankle is of potential value in selected patients with mild to moderate dorsoposterior digital contractures in conjunction with traditional podiatric treatment.

Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open.
Muscles of the Forearm that Move the Hand and Fingers
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...

Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
