What is the movement at the ankle?
Movement at the ankle is key for maintenance of posture and balance, but is most important in locomotion. Variation in muscle activation can control the movement of the ankle joint, allowing the foot to generate graduated force. Muscles that generate movement at the ankle are generally found in the lower leg and can be split into three categories.
What are the tendons that cross the ankle?
Have tendons that cross the ankle and attach on the bones of the foot to assist in movement Dorsi-flexion Upward movement of the foot Plantar Flexion Downward movement of the foot Inversion The movement of the sole medially at the ankle joint Eversion The movement of the sole of the foot laterally at the ankle joint Divided into three compartments
What are the different parts of the ankle?
The ankle consists of two joints which permit dorsiflexion, plantarflexion, inversion, and eversion of the foot. Strong ligaments hold the ankle joint in place, although it is susceptible to damage. Muscles controlling movement at the ankle are found in the leg and can be split into anterior, posterior, and lateral compartments.
What causes lateral ankle sprains?
Over development of the ankle extensors tends to also cause a muscular imbalance between the strength of the foot supinator and pronator muscles, which may result in lateral ankle sprains, particularly when landing after being airborne. The muscles of the ankle and foot have a very intricate structure.
What controls the movement of the ankle?
Peroneal tibial muscle: controls movement on the outside of the ankle. Extensors: enable the ankle to raise the toes just before stepping forward. Flexors: stabilize the toes against the floor.
What muscles flex the ankle?
The plantaris muscle works in conjunction with the Achilles tendon to flex your ankle and knee. You use this muscle every time you stand on your tiptoes.
Which muscle or muscles can extend the ankle?
The extensor digitorum longus and the extensor hallucis longus dorsiflex the ankle and extend the toes, which lifts the toes off the floor when standing. These muscles are used when walking upstairs to make sure the toes clear the step.
What are the two movements of the ankle?
Flexion and extension at the ankle are referred to as dorsiflexion and plantarflexion, respectively (Figure 2). “Dorsi” refers to the top of the foot, while “plantar” refers to the bottom of the foot. The term “flexion” is incorporated to indicate movement upwards (dorsiflex) or downwards (plantarflex).
What muscle controls foot movement?
Tibialis anterior: This muscle runs from the tibia to the first toe, and helps make walking possible by flexing the foot upward and turning it inward. Extensor digitorum longus: This is one of three muscles that pull the foot upward. It also extends the toes, lifts the toes, and turns the foot outward.
Which muscle must contract to bend the ankle?
The plantaris tendon runs below both the soleus and gastrocnemius muscles to connect directly with the heel bone. This muscle works with the Achilles tendon to flex both the ankle and knee joints, allowing a person to stand on their toes or point their foot in plantar flexion.
What are the ankle muscles?
The major muscles of the ankle include the gastrocnemius and soleus (calf) muscles, which push the foot down and allow us to go up on our toes. These two large muscles join at the ankle to form the Achilles tendon.
What does the gastrocnemius and soleus do?
The soleus connects to your tibia and fibula (the bones in your lower leg). Together with your gastrocnemius, the soleus helps you walk, run and jump. It also helps your legs support you so you can maintain good posture.
Which muscle causes ankle plantar flexion?
The action of soleus, gastrocnemius, and plantaris is to produce plantar flexion at the ankle joint. Their action lifts us up off the ground when we stand on tip-toe.
What type of movement is the ankle joint?
Overview. The ankle joint is a hinged synovial joint with primarily up-and-down movement (plantarflexion and dorsiflexion).
Which muscle is responsible for dorsiflexion of the foot?
tibialis anteriorThe foot and ankle dorsiflexors include the tibialis anterior, the extensor hallucis longus (EHL), and the extensor digitorum longus (EDL). These muscles help the body clear the foot during swing phase and control plantarflexion of the foot on heel strike.
What is dorsiflexion of the ankle?
Dorsiflexion occurs in your ankle when you draw your toes back toward your shins. You contract the shinbones and flex the ankle joint when you dorsiflex your foot. You can also dorsiflex your foot by lifting the ball of your foot off the ground while standing, keeping your heel planted into the ground.

Which part of the foot is extended by the extensor hallucis brevis?
The hallux or large toe is extended by the extensor hallucis brevis on the top of the foot. The flexor hallucis brevis and abductor hallucis flex and abduct the big toe. The adductor hallucis adducts the big toe. The remaining toes are flexed by the flexor digitorum longus, lumbricals, flexor digitorum brevis, and quadratus plantae.
Why is it important to have muscle strength on both sides of the ankle and foot?
Having muscle strength on both sides of the ankle and foot is important in maintaining joint integrity. Any imbalances in the strength or flexibility of the surrounding musculature result in misalignment. This in turn must be counteracted by muscular contractions or ligament tension. If not, postural imbalances occur.

They are inversion and eversion, which take place between the talus (ankle bone), the navicular (tarsal bone), and the calcaneus (heel bone).
What is the movement of the toe area of the foot away from the body?
The second is extension, also known as plantar flexion, or the movement of the toe area of the foot away from the body. In plantar flexion there are simultaneous movements of the foot around the subtalar and ankle axes, i.e., a combination of eversion at the subtalar joint and extension at the ankle joint.
What is the movement of the toe area of the foot toward the shin called?
The first is flexion, also known as dorsiflexion, or the movement of the toe area of the foot toward the shin. In this action there is a combination of inversion at the subtalar joint and dorsiflexion at the ankle joint when executing ankle joint flexion. The second is extension, also known as plantar flexion, or the movement of the toe area ...
Do shin splints cause postural imbalance?
If not, postural imbalances occur. Athletes with shin splints usually have significantly greater plantar flexor (extensor) strength than dorsiflexor (flexion) strength and greater movement of the calcaneus during the support phases of running and walking.

Why do muscles not move?
Most of the time, muscles do not move unless the brain signals for them to do so. However, these signals sometimes get mixed up. The mix-up may occur in the brain, the nerves that send the signals, or the muscles that receive them. When signal misfires occur, the muscles can move involuntarily, which people usually refer to as a twitch.
