Abstract:
In humans the sural nerve was stimulated at one of 16 phases of the step cycle. In MG (medial gastrocnemius) the amplitude of the P2 responses (latency 80-93 ms) was on average 1.3 times larger than the corresponding background activity while this was 0.9 for LG (lateral gastrocnemius; predominantly suppressive responses). It is speculated that such differences contribute to an exorotation moment during gait.

Muscles that Move the Leg
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

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...
