Overview The peroneal nerve controls the muscles that lift your foot. This nerve runs near the surface of your skin on the side of your knee closest to your hand. Activities that compress this nerve can increase your risk of foot drop. Examples include: Crossing your legs.

Muscles of the Foot The muscles acting on the foot can be divided into two distinct groups; extrinsic and intrinsic muscles. 1  The extrinsic muscles arise from the anterior, posterior and lateral compartments of the leg. 2  They are mainly responsible for actions such as eversion, inversion, plantarflexion and dorsiflexion of the foot. They are mainly responsible for actions such as eversion, inversion, plantarflexion and dorsiflexion of the foot. 2  The intrinsic muscles are located within the foot and are responsible for the more fine motor actions of the foot, for example movement of individual digits.

Chapter 17: The ankle and foot The chief movements of the foot distal to the ankle joint are inversion and eversion. In inversion, the sole of the foot is directed medially. In eversion, the sole is turned so that it faces laterally (see fig. 17-6).he foot may be disarticulated at the ankle joint (Syme's amputation) or at the transverse tarsal joint (Chopart's amputation). The tension that develops during the support of body weight is taken up by strong ligaments on the plantar aspect of the tarsus (figs. 17-8 and 17-9).

Muscular Function and Anatomy of the Lower Leg and Foot Muscles of the Foot. These movements are performed by the same sets of muscles that allow dorsal and plantar flexion. Most of these muscles originate on the shaft of the tibia or fibula of the lower leg, these bones here. They travel down to your leg and insert into the tendons or bones in your ankle and foot.

Muscles of the Leg and Foot From the large, strong muscles of the buttocks and legs to the tiny, fine muscles of the feet and toes, these muscles can exert tremendous power while constantly making small adjustments for balance – whether the body is at rest or in motion.

Tibialis anterior The muscle inserts into the base of the first metatarsal bone in the foot, located just behind the big toe. It also inserts to the medial and inferior surfaces of the medial cuneiform tarsal. The tibialis anterior muscle helps with dorsiflexion, which is the action of pulling the foot toward the shin.It also inverts (tilts inward) the foot at the subtalar and midtarsal joints and holds up the medial longitudinal arch of the foot.n general, muscles of this compartment help to flex the foot in an upward direction at the ankle and also extend the toes. The tibialis anterior muscle emerges from the upper lateral (outer) surface of the tibia, or shinbone, and from the interosseous membrane.

Walking and Gaits These muscles dorsiflex the foot, which is required during the swing phase to clear the toes away from the ground. If the deep fibular nerve is damaged, then the foot cannot be dorsiflexed, and drags along the ground during the swing phase.

Muscles that Move the Ankle and Foot Many muscles do the work of moving the ankle and foot. Some of the muscles that move the foot start higher up in the leg, and smaller muscles work right in the foot itself. The leg is divided into compartments: the anterior, lateral, and posterior compartments.The muscles in these compartments help move the ankle and the foot:Anterior compartment: This compartment lies in front of the tibia and fibula and is surrounded by fascia. The anterior muscles dorsiflex the foot at the ankle and extend the toes.ome of the muscles that move the foot start higher up in the leg, and smaller muscles work right in the foot itself.

UNIT VIII â The Foot and Ankle This muscle is the strongest dorsiflexor of the foot and ankle. It also assists with inversion of the ankle. This muscle passes down the front of the lower leg and attaches on the inside (medial) aspect of the foot so when it contracts it pulls the foot up and in.hese are all muscles that run from the lower leg and attach on the medial aspect of the foot. When these muscles contract they pull the insertion toward the origin and thus pull the sole of the foot toward the inside or medial aspect of the body.

Flexor hallucis longus muscle Similar to the flexor digitorum longus and tibialis posterior muscles, the flexor hallucis longus muscle functions to plantar flex and invert the foot. However, it is unique in that it also functions to flex the great toe and helps supinate the ankle.

Muscles The calf muscles are pivotal to movement of the ankle, foot, and toes. Some of the major muscles of the calf include: Gastrocnemius (calf muscle): One of the large muscles of the leg, it connects to the heel. It flexes and extends the foot, ankle, and knee.

What is Pronation and Supination? Supination (or under-pronation) is the opposite of pronation and refers to the outward roll of the foot during normal motion. A natural amount of supination occurs during the push-off phase of the running gait as the heel lifts off the ground and the forefoot and toes are used to propel the body forward. moderate amount of pronation is required for the foot to function properly, however damage and injury can occur during excessive pronation. When excessive pronation does occur the foot arch flattens out and stretches the muscles, tendons and ligaments underneath the foot.

If Feet Turn Out the Piriformis Muscle is Short The piriformis muscle turns out the foot by externally rotating a straight leg and slightly abducting (pull away) a leg when the knee bends. It does this by engaging and contracting in order to turn the leg open.

- High Tone Pronation or Supination. 1  Pronation: 2  Foot collapses and medial arch flattens. Heel everts and forefoot abducts. 3  Supination: Foot bears weight on lateral side, high medial arch. Heel inverts and forefoot adducts.

Muscles of the Foot There are 10 intrinsic muscles located in the sole of the foot. They act collectively to stabilise the arches of the foot, and individually to control movement of the digits. All the muscles are innervated either by the medial plantar nerve or the lateral plantar nerve, which are both branches of the tibial nerve.

Ankle Flexion and Extension Although inversion and eversion are actions not of the ankle joint but of the foot, the musculature within the lower leg acts directly on the foot and needs no assistance from other muscles to create motion.Pronation and supination occur not in the foot but in its subtalar joint. A Kinesiological Look at the Lower Leg.he ankle is composed of the distal tibia, distal fibula and dome of the talus (also known as the ankle mortise or mortise joint). The foot is composed of 26 bones and 33 joints and has many intrinsic and extrinsic muscles.

- When you evert your foot, you will be standing on the inner edge of your foot. If you do it with both feet at the same time, your feet will make the letter v, for eVersion. The peroneus longus, peroneus brevis and peroneus tertius are responsible for foot eversion and run along the outside of your leg.

Supination Inversion is where the sole of the foot is turned inwards, plantar flexion is where the foot and toes point downwards and adduction of the ankle involves the toes pointing across the body. Combine all three movements and you have supination.When standing, supination occurs as the foot rolls outwards, placing most of the weight onto the outside of the foot and raising the arch. Supination is a normal part of the gait cycle (walking/running) which allows the foot to form a rigid structure for propulsion.The opposite movement to supination is pronation, this is also a normal part of the gait cycle and when excessive is termed overpronation.nversion is where the sole of the foot is turned inwards, plantar flexion is where the foot and toes point downwards and adduction of the ankle involves the toes pointing across the body. Combine all three movements and you have supination.
