Not a content of the tarsal tunnel?:*Flexor hallucis longusFlexor digitorum longusPosterior tibial arteryTibialis anterior

The tarsal tunnel is a narrow space that lies on the inside of the ankle next to the ankle bones. The tunnel is covered with a thick ligament (the flexor retinaculum) that protects and maintains the structures contained within the tunnel—arteries, veins, tendons, and nerves. One of these structures is the posterior tibial nerve, the main focus of tarsal tunnel syndrome.

The contents of the tarsal tunnel include:

1. Tibialis posterior tendon
2. Flexor digitorum longus tendon
3. Posterior tibial artery and veins
4. Tibial nerve
5. Flexor hallucis longus tendon

Therefore, the "Tibialis anterior" is not a content of the tarsal tunnel.
