Caudal tibial muscle - Musculus tibialis caudalis


In hoofed animals, the caudal tibial muscle is one of the three proximal heads of the deep digital flexor muscle that lies on the caudal surface of tibia covered by the gastrocnemius and the superficial digital flexor. 

Origin: tibia and fibula

Insertion: the distal phalanx(ges) via the common tendon of deep digital flexor muscle

Action: flexor of digits

Nerve: Tibial


In carnivores, the caudal tibial muscle is completely separated from the deep digital flexor muscle, in contrast with the hoofed animals. As an insignificant spindle-shaped muscle, it lies between the two heads (lateral and digital flexor muscles) of the deep digital flexor muscle. It is covered by the medial digital flexor muscle and lies directly on the caudal surface of the tibia. It arises on the medial part of the proximal end of the fibula and after a short course, forms a very delicate tendon that extends distally cranial to the somewhat larger tendon of the medial flexor muscle, an ends ont the medial ligamentous tissue or the tarsus. Exceptionally, this muscle may be lacking.

Origin: Medial part of the proximal end of the fibula.

Insertion: Medial ligamentous masses of the tarsus.

Action: Extension of the tarsus; outward rotation of the foot.

Nerve: Tibial
