The Ankle and Foot Joints

A collection of vocabulary flashcards based on key concepts from the lecture on the ankle and foot joints.

Dorsiflexion

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

Plantar flexion

Movement of the ankle and foot away from the tibia.

Inversion

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

Eversion

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

Pronation

Combination of ankle dorsiflexion, subtalar eversion, and forefoot abduction (toe-out).

Supination

Combination of ankle plantar flexion, subtalar inversion, and forefoot adduction (toe-in).

Talocrural joint

Hinge or ginglymus-type joint formed by the talus, distal tibia, and distal fibula.

Syndesmosis

A type of fibrous joint where bones are connected by a ligament, allowing minimal movement.

Achilles tendon

The tendon connecting the calf muscles to the heel bone, involved in plantar flexion.

Plantar fasciitis

A common painful condition involving the plantar fascia that stabilizes the medial longitudinal arch.

Compartment Syndrome

A painful condition due to increased pressure within a muscle compartment, often requiring surgical intervention.

Tibialis anterior

A muscle responsible for dorsiflexion and inversion of the foot.

Peroneus longus

A muscle involved in eversion and plantar flexion of the foot.

Intrinsics of the foot

Muscles originating and inserting within the foot, responsible for toe movements.

Medial longitudinal arch

The arch extending from the calcaneus to the medial aspects of the foot.

Lateral longitudinal arch

The arch extending from the calcaneus to the lateral aspects of the foot.

Transverse arch

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

Metatarsophalangeal joint

Joint where the phalanges meet the metatarsals, allowing for flexion and extension of the toes.
