Question

Behind the medial malleolus and in front of Achilles, which artery is present?

• A. Posterior tibial artery
• B. Peroneal artery
• C. Anterior tibial artery
• D. Dorsalis pedis artery

Hint:

When studying the arterial system of the lower limb, it is important to remember the locations and functions of the major arteries like the posterior tibial and dorsalis pedis.

Answer 1

The Correct Option is A

The question requires identifying an artery located behind the medial malleolus and in front of the Achilles tendon.

This specific anatomical positioning is associated with the posterior tibial artery.

Let's break down the anatomical landmarks:

• Medial malleolus: This is the bony prominence on the inner side of the ankle, formed by the lower end of the tibia.
• Achilles tendon: A tendon located at the back of the ankle connecting the calf muscles to the heel bone.

The space between these structures is part of the tarsal tunnel. This tunnel contains structures passing into the foot, including:

• Tibialis posterior tendon
• Flexor digitorum longus tendon
• Posterior tibial artery
• Tibial nerve
• Flexor hallucis longus tendon

Of these, the posterior tibial artery is the vessel running directly in this region. Thus, the correct answer is:

Posterior tibial artery
