Ankle Anatomy and Function Assessment

This video tutorial provides an in-depth understanding of the anatomy of the foot and ankle. It covers the structure of the ankle joint, including the tibia, fibula, and talus bones, as well as the medial and lateral ligaments. The tutorial also explores the tendons and muscles, such as the Achilles tendon, gastrocnemius, and soleus, and their roles in providing stability and movement. Additionally, it discusses the movements of the ankle, including dorsiflexion, plantar flexion, inversion, and eversion, and their functional significance in activities like walking and running.

What type of joint is the ankle joint?

• Pivot joint

• Saddle joint

• Hinge joint

• Ball and socket joint

Which ligament is considered stronger in the ankle?

• Medial or deltoid ligament

• Posterior talofibular ligament

• Calcaneofibular ligament

• Anterior talofibular ligament

Which ligament is more prone to injury in a twisted ankle?

• Medial or deltoid ligament

• Anterior talofibular ligament

• Calcaneofibular ligament

• Posterior talofibular ligament

What is the primary function of the Achilles tendon?

• To support the arch of the foot

• To connect the femur to the tibia

• To protect the ankle from sprains

• To provide mechanical strength and stability

What is the role of the retro calcaneal bursa?

• To connect the Achilles tendon to the tibia

• To maintain constant distance between the ankle joint and Achilles

• To support the arch of the foot

• To protect the ankle from sprains

Which muscles are primarily involved in the spring-like action during walking and running?

• Hamstrings and quadriceps

• Gastrocnemius and soleus

• Peroneus longus and brevis

• Tibialis anterior and posterior

What is the function of the tibialis posterior muscle?

• To flex the knee

• To stabilize the ankle

• To rotate the hip

• To extend the toes

What is dorsiflexion?

• Pointing the toes downward

• Rotating the foot outward

• Pointing the toes upward

• Rotating the foot inward

Which movement is less important in functional activities like squatting?

• Dorsiflexion

• Eversion

• Plantar flexion

• Inversion

What is inversion of the foot?

• Pointing the toes downward

• Pointing the toes upward

• Rotating the sole of the foot inward

• Rotating the sole of the foot outward
