Ankle Anatomy and Function

The video tutorial provides a comprehensive overview of the ankle's anatomy, including bones, joints, ligaments, tendons, muscles, nerves, and blood vessels. It explains the structure and function of the ankle joint, highlighting the role of articular cartilage. The tutorial details the ligaments and tendons that stabilize the ankle, as well as the muscles and tendons essential for movement. It also covers the nerve and blood supply to the ankle, emphasizing the importance of these components in maintaining ankle health and function.

What is the bony bump on the lateral side of the ankle called?

• Calcaneus

• Medial malleolus

• Lateral malleolus

• Talus

Which bone fits inside the ankle socket to allow foot movement?

• Tibia

• Fibula

• Talus

• Calcaneus

What is the function of articular cartilage in the ankle joint?

• To connect muscles to bones

• To allow smooth movement of bones

• To provide blood supply

• To transmit nerve signals

What is the main difference between ligaments and tendons?

• Ligaments attach bones to bones, tendons attach muscles to bones

• Ligaments attach muscles to bones, tendons attach bones to bones

• Ligaments are made of collagen, tendons are not

• Ligaments are thicker than tendons

Which ligament complex supports the lateral side of the ankle?

• Anterior talofibular ligament

• Posterior tibial ligament

• Lateral ligament complex

• Deltoid ligament

What is the role of the Achilles tendon?

• To support the arch of the foot

• To allow dorsiflexion

• To enable walking, running, and jumping

• To stabilize the ankle joint

Which muscle is attached to the posterior tibial tendon?

• Posterior tibialis

• Soleus

• Gastrocnemius

• Peroneus longus

Which nerve runs behind the medial malleolus?

• Sural nerve

• Deep peroneal nerve

• Posterior tibial nerve

• Superficial peroneal nerve

Where can you feel the pulse of the dorsalis pedis artery?

• Behind the medial malleolus

• In the middle of the top of the foot

• On the lateral side of the ankle

• At the base of the fifth metatarsal

What is the function of the superficial peroneal nerve?

• To stabilize the ankle joint

• To provide sensation to the top and outside edge of the foot

• To control the muscles in the sole of the foot

• To supply blood to the ankle
