Dissection of plantar aspect of left foot
Flexor tendons within digital tendon sheaths
The digital tendon sheaths of the four medial toes have been opened to expose the tendons of the long and short muscles in situ within the sheaths. The proximal limit of the synovial sheath for the tendons of the third toe is indicated at 11. A small artery is visible in this area passing along a part of the synovial membrane that lies superficial to the tendon and is attached to it as a sort of mesotendon.
- Tendon of flexor hallucis longus muscle
- Branch of dorsal digital artery
