KIN 480- Lecture 10: Foot and Ankle

These flashcards cover essential vocabulary and concepts related to the foot and ankle anatomy, focusing on joints, muscles, and movements.

Talocrural joint

Ankle joint, also known as the hinge or ginglymus-type joint, between the talus, distal tibia, and distal fibula.

Intertarsal joints

Joints between tarsal bones classified as gliding or arthrodial, allowing minimal movement.

Eversion

Turning the ankle and foot outward; abduction away from the midline.

Inversion

Turning the ankle and foot inward; adduction toward the midline.

Plantar flexion

Movement of the ankle and foot away from the tibia.

Dorsiflexion

Movement of the top of the ankle and foot toward the anterior tibia.

Metatarsophalangeal joints

Joints where phalanges join metatarsals, classified as condyloid-type joints.

Syndesmosis joint

A fibrous joint between the tibia and fibula, allowing for minimal movement.

Tibialis anterior

Muscle responsible for dorsiflexion of the foot.

Achilles tendon

The tendon connecting calf muscles to the heel bone, prone to ruptures.

Dorsiflexors

Muscles that perform dorsiflexion of the ankle, including tibialis anterior and extensor digitorum longus.

Evertors

Muscles that cause eversion of the foot, including peroneus longus and peroneus brevis.

Plantar flexors

Muscles that perform plantar flexion, including gastrocnemius and soleus.

Longitudinal arches

Arches of the foot consisting of the medial and lateral arches that help maintain stability.

Transverse arch

Arch extending across the foot from the 1st metatarsal to the 5th.

Pronation

A combination of ankle dorsiflexion, subtalar eversion, and forefoot abduction.

Supination

A combination of ankle plantar flexion, subtalar inversion, and forefoot adduction.

'Tom, Dick & Harry' muscles

Refers to tibialis posterior, flexor digitorum longus, and flexor hallucis longus, essential for foot movement.

Shin splints

Common term for painful leg condition often linked to running, not a specific diagnosis.

Anterior inferior tibiofibular ligament

Ligament primarily involved in 'high ankle sprains'.

Deep posterior compartment

Compartment of the lower leg containing flexor digitorum longus and flexor hallucis longus among other muscles.

Ligaments of the ankle

Structures that maintain stability and support the arches of the foot.
