Plantar flexion is performed by the muscles of the posterior compartment of the leg, eg gastronemius (mainly) and soleus; other muscles such as plantaris have a weak contribution. The spinal roots are S1 and S2 fibers of the posterior tibial nerve.
Foot eversion is performed by the fibularis longus and brevis (both in the lateral compartment of the leg). They are supplied by the superficial peroneal nerve (L5, S1).
What else can I help you with?
Why does the gastrocnemius muscle contract after stimulating the sciatic nerve?
The gastrocnemius is stimulated by a branch of the sciatic nerve called the tibial nerve. This causes contraction and produces plantar flexion of the foot. When a person stands on their "tippy toes" that is plantar flexion. This is a function of this nerve.
Achilles tendon when hit with a refelx hammer?
Hitting the Achilles tendon with a reflex hammer can elicit a normal reflex called the Achilles reflex or ankle jerk. This test assesses the integrity of the S1 and S2 nerve roots. A brisk contraction of the calf muscles and a slight plantar flexion of the foot is the normal response.
Which nerve is important for the ankle jerk reflex?
medial popliteal nerve
What is the nerve carrying motor information causing the right leg flexion when you step on a nail?
The nerve carrying motor information causing right leg flexion when stepping on a nail would be the sciatic nerve. This nerve is responsible for providing motor function to the muscles of the lower limb, including the hamstrings which are involved in flexing the leg in response to a painful stimulus like stepping on a nail.

What is the function of a Tibial Nerve?
The Tibial nerve provides motor and sensory innervation to the posterior compartment of the leg and sole of the feet. Injury to the nerve could produce loss in flexion of the toes and feet.
What does Tibial nerve do?
Tibial nerves main function is to plantar flex and invert the foot
What are the 31 spinal nerves called?
The proper name is Mixed Spinal Nerve.They do not have individual names, however. They are referred to by their number, with number one just above the first rib and the 31st going through the foramen between sacral 4 & 5.
Which muscle compartment is involved in eversion joint movement?
The muscles involved in eversion joint movement are primarily located in the lateral compartment of the lower leg. These include muscles such as the peroneus longus and peroneus brevis. These muscles work together to move the foot outward and help with stability during walking and running.
What is the root value of common peroneal nerve?
The common peroneal nerve, also known as the common fibular nerve, is primarily derived from the L4-S2 nerve roots. It branches from the sciatic nerve in the posterior thigh and innervates muscles in the lower leg and foot. Its role includes motor functions for dorsiflexion and eversion of the foot, as well as sensory functions in the skin of the lower leg and the dorsum of the foot.
What is the function of the medial nerve?
The median nerve provides sensory and motor function to the hand and forearm. It innervates muscles involved in flexion of the wrist and fingers, as well as sensation to the palm and fingers. Injury to the median nerve can result in weakness, numbness, and tingling in the hand and fingers.
