What Innervates the peroneus brevis?
Innervation. Motoric innervation to the fibularis brevis muscle is provided by the superficial fibular (peroneal) nerve (L5-S1). This is a branch of the common fibular division of sciatic nerve. Cutaneous innervation to the skin overlying this muscle is mitigated by the spinal nerve roots L5, S1 and 2.
What is the function of M peroneus longus?
Function. The peroneus longus courses down the lateral aspect of your lower leg and attaches around the lateral foot and on the bottom of your foot. When it contracts, it moves your ankle into eversion. This motion is when your ankle moves to the side towards your smallest toe.

Where is the Peroneals?
lower leg
Anatomical terms of muscle The fibularis muscles (also called peroneus muscles or peroneals) are a group of muscles in the lower leg.
Is peroneus longus a flexor or extensor?
In human anatomy, the fibularis longus (also known as peroneus longus) is a superficial muscle in the lateral compartment of the leg. It acts to tilt the sole of the foot away from the midline of the body (eversion) and to extend the foot downward away from the body (plantar flexion) at the ankle.
Where are your Peroneals?
The Peroneus Longus lies superficial to the Peroneus Brevis and is the largest of the Peroneal muscles. The Peroneal Longus extends down the lateral compartment of the lower limb where at the midpoint it tapers in to a long tendon that descends in to the foot.
What nerve is in the peroneal nerve?
the sciatic nerve
The peroneal nerve is a branch of the sciatic nerve, which supplies movement and sensation to the lower leg, foot and toes. Common peroneal nerve dysfunction is a type of peripheral neuropathy (damage to nerves outside the brain or spinal cord).
What is the peroneus longus?
The peroneus longus is an important muscle in your lower leg. It starts at the top of the fibula before running down the outside of the leg and connecting to the foot with the peroneus longus tendon. Your peroneus longus muscles help you move your ankles, flex your feet, and maintain your balance.
What muscles are Everts Dorsiflexes?
Fibularis (peroneus) tertius: This muscle originates on the anterior surface of the shaft of the fibula and inserts on the base of the fifth metatarsal bone. It dorsiflexes the ankle and everts the foot.
What nerve innervates the flexor hallucis longus muscle?
the tibial nerve
Innervation. Flexor hallucis longus is innervated by the tibial nerve, composed of spinal roots L4, L5, S1, S2, and S3.
Where is the peroneus longus muscle located?
The peroneus longus muscle is one of two muscles in the lateral compartment of the lower limb along with the peroneus brevis muscle.[1] The lateral compartment receives innervation from the superficial peroneal nerve (L5-S2), supplied by the anterior tibial and peroneal arteries.
What nerve innervates the peroneus longus?
The peroneus longus muscle receives innervation from the superficial peroneal nerve. The superficial peroneal nerve is one of the terminal branches of the common peroneal nerve, which originates from the sciatic nerve (L4-S3).[10]
What does the muscleperoneus longus do?
The muscleperoneus longus It is an extrinsic muscle of the foot that runs along the outside of the leg.Together with the peroneus brevis, it forms the lateral muscle compartment l of the lower limbs. Your muscular body is directed downward, running through the entire fibula bone.
What causes pain in the peroneus longus nerve?
The nerve that innervates your peroneus longus emerges from your low back, and a problem there from arthritis or a herniated disc may cause the nerve to become pinched. This may result in pain in your lower leg and weakness in the muscles that move your ankle.
