Question

This is an axial T1 MRI of the ankle, at the level of the superior articular surface of talus. What are the structures marked A) to F) in the image? A= Anterior tibiotalar ligament, B= Flexor digitorum longus tendon, C= Tibialis posterior tendon, D= Achilles tendon, E= Lateral malleolus, F= Calcaneus A= Tibialis anterior tendon, B= Flexor digitorum longus tendon, C= Tibialis posterior tendon, D= Achilles tendon, E= Fibular shaft, F= Talofibular joint A= Tibialis anterior tendon, B= Tibialis posterior tendon, C= Flexor digitorum longus tendon, D= Achilles tendon, E= Calcaneus, F= Subtalar joint A= Tibialis anterior tendon, B= Tibialis posterior tendon, C= Flexor digitorum longus tendon, D= Achilles tendon, E= Lateral malleolus, F= Talofibular joint

Answer 1

The structures marked in the image are the anterior tibiotalar ligament, flexor digitorum longus tendon, tibialis posterior tendon, Achilles tendon, lateral malleolus, and calcaneus. These structures play important roles in supporting the ankle joint and enabling movement of the foot.

Step-by-step explanation:

The structures marked in the image are as follows:

A) Anterior tibiotalar ligament: It is an intrinsic ligament located on the lateral side of the ankle joint, between the talus bone and the lateral malleolus of the fibula. It supports the talus at the talocrural joint and resists excess inversion of the foot.

B) Flexor digitorum longus tendon: It is a tendon that runs along the back of the leg and attaches to the underside of the foot. It helps to flex the toes.

C) Tibialis posterior tendon: It is a tendon that runs along the back of the leg and attaches to the underside of the foot. It helps to support the arch of the foot and invert the foot.

D) Achilles tendon: It is the largest tendon in the body and attaches the calf muscles to the heel bone. It allows for plantar flexion of the foot.

E) Lateral malleolus: It is the bony prominence on the outer side of the ankle and is part of the fibula bone.

F) Calcaneus: It is the heel bone and is the largest bone in the foot.
