2. Canalis carpalis
3. Vagina synovialis communis mm. flexorum
4. Vagina tendinis m. flexor carpi radialis
5. Vagina tendinis m. flexor pollicis longi

Explanation

The synovial sheath of the little finger:It covers the flexor digitorum superficialis and Profundo's muscles. Superiorly this sheath protrudes 12 cm proximal to the flexor retinaculum. Interiorly it extends on the flexors until the base of the distal phalanx ofthe little finger.
