Musculus fibularis (peroneus) tertius represents a small portion of the extensor digitorum longus. Insertion: The origin is on the lower third of the anterior part of the fibula and interosseus membrane. Distal insertion of this muscle is on the dorsal surface of the fifth metatarsal base. Its tendon for distal insertion lies under the retinaculum of all the extensor muscles. Action: Dorsiflexor of the ankle and everts the foot. Innervation is assured by the deep peroneal nerve. Ventral muscles are shown by Figure 3.20a.

When the two ends of the sensors were met, the strap forms a circle with a diameter of about 4.5 cm which was sufficient to cover the distal portion of the forearm of an average adult as illustrated in Figure 4. The area of the sensor matrix span over the muscle-tendon of multiple major muscle groups such as brachioradialis, flexor carpi radialis, palmaris longus, flexor carpi ulnaris, extensor carpi ulnaris, extensor digitorum, etc. The area also covers a region of the flexor retinaculum and the extensor retinaculum that are near the wrist.
