What is the name of the membrane which holds the tibia and fibula together and what is its purpose
Interossseus membrane. Maintains the integrity of the mortise.
What are the three ligaments of the lateral collateral complex?
- Anterior talofibular
- Posterior talofibular
- Calcaneofibular
Joint created between the distal and middle phalanges of each toe; allow flexion and extension?
Distal interphalangeal Joint (DIP)
Joint created between the middle and proximal phalanges of each toe; allow flexion and extension?
Proximal Interphalangeal Joint (PIP)
Joint created between the proximal phalanx and metatarsal of each toe; allow flexion and extension?
Metarsophalangeal Joint (MP)
Connection between the medial malleolus, lateral malleolus and the talus; allows plantar flexion and dorsiflexion.
Ankle joint
Joint created between the talus and calcaneus; allows inversion and eversion
Subtalar Joint
What is the action of the Gastrocnemius?
Plantar-flexion when knee is extended
Knee Flexion
Raises heel during walking
Action of the Soleus?
Plantar-flexion
Steadies leg on foot
Which ligament is commonly damaged ?

What does the ATFL connect to?
Talus to the fibula
What does the calcaneofibular Ligament connect to ?
Fibula to the Calcaneus inferiorly
What does the anterior and posterior tibiotalar ligament connect to?
Tibia to the talus
Where does the tibionavacular attach to?
Navicular anteriorly and the tibiocalcaneal ligament which attaches to the calcaneus inferiorly
