  2. Myotome - Wikipedia

    en.wikipedia.org/wiki/Myotome

    A myotome is the group of muscles that a single spinal nerve innervates. [1] Similarly a dermatome is an area of skin that a single nerve innervates with sensory fibers. Myotomes are separated by myosepta (singular: myoseptum). [2] In vertebrate embryonic development, a myotome is the part of a somite that develops into muscle.

  3. Tibialis anterior muscle - Wikipedia

    en.wikipedia.org/wiki/Tibialis_anterior_muscle

    The movements of tibialis anterior are dorsiflexion and inversion of the ankle. However, actions of tibialis anterior are dependent on whether the foot is weight bearing or not (closed or open kinetic chain). When the foot is on the ground, the muscle helps to balance the leg and talus on the other tarsal bones so that the leg is kept vertical ...

  4. Foot drop - Wikipedia

    en.wikipedia.org/wiki/Foot_drop

    A patient recovering from surgery to treat foot drop, with limited plantar and dorsiflexion.. Foot drop is a gait abnormality in which the dropping of the forefoot happens out of weakness, irritation or damage to the deep fibular nerve (deep peroneal), including the sciatic nerve, or paralysis of the muscles in the anterior portion of the lower leg.

  5. Ankle jerk reflex - Wikipedia

    en.wikipedia.org/wiki/Ankle_jerk_reflex

    The ankle jerk reflex, also known as the Achilles reflex, occurs when the Achilles tendon is tapped while the foot is dorsiflexed.It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it.

  6. Extensor hallucis longus muscle - Wikipedia

    en.wikipedia.org/wiki/Extensor_hallucis_longus...

    Occasionally united at its origin with the extensor digitorum longus.. The extensor ossis metatarsi hallucis, a small muscle, sometimes found as a slip from the extensor hallucis longus, or from the tibialis anterior, or from the extensor digitorum longus, or as a distinct muscle; it traverses the same compartment of the transverse ligament with the extensor hallucis longus.

  7. Latissimus dorsi muscle - Wikipedia

    en.wikipedia.org/wiki/Latissimus_dorsi_muscle

    Compound exercises for the 'lats' typically involve elbow flexion and tend to recruit the biceps brachii, brachialis, and brachioradialis for this function. Depending on the line of pull, the trapezius muscles can be recruited as well; horizontal pulling motions such as rows recruit both latissimus dorsi and trapezius heavily.

  8. Tibial nerve - Wikipedia

    en.wikipedia.org/wiki/Tibial_nerve

    The tibial nerve is the larger terminal branch of the sciatic nerve with root values of L4, L5, S1, S2, and S3. It lies superficial (or posterior) to the popliteal vessels, extending from the superior angle to the inferior angle of the popliteal fossa, crossing the popliteal vessels from lateral to medial side.

  9. Flexor hallucis longus muscle - Wikipedia

    en.wikipedia.org/wiki/Flexor_hallucis_longus_muscle

    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.
