Talus

This video tutorial from Kenhub explores the anatomy of the talus, one of the tarsal bones in the foot. It covers the talus's position among the seven tarsal bones, its role as the ankle bone, and its anatomical features, including the head, neck, and body. The tutorial also discusses the talus's articulations with other bones, the ligaments attached to it, and its blood supply and innervation. The video concludes with a call to explore more resources on Kenhub.

Which bone is known as the ankle bone?

• Calcaneus

• Cuboid

• Talus

• Navicular

What are the three main components of the talus bone?

• Head, neck, and body

• Body, shaft, and head

• Head, shaft, and base

• Neck, shaft, and base

Which ligament is also known as the spring ligament?

• Plantar calcaneonavicular ligament

• Deltoid ligament

• Posterior talofibular ligament

• Anterior talofibular ligament

Which joint is formed by the talus and calcaneus?

• Talocrural joint

• Subtalar joint

• Metatarsophalangeal joint

• Tarsometatarsal joint

Which artery is NOT a source of blood supply to the talus?

• Posterior tibial artery

• Anterior tibial artery

• Perineal artery

• Dorsalis pedis artery

Why is the blood supply to the talus considered tenuous?

• It has a dense network of veins.

• It is mostly cartilage with limited blood vessels.

• It has a high number of muscle attachments.

• It is located far from major arteries.

Which nerve does NOT provide innervation to the talus?

• Deep fibular nerve

• Saphenous nerve

• Sural nerve

• Radial nerve
