Origin

Proximal end of the tibia (cranial border and lateral surface), head of the fibula and interosseous membrane.

Medial side of the distal tarsus, on the rudimentary metatarsal bone I.

Flexes the tarsus.

Common fibular (peroneal) nerve (n. fibularis communis).

In the neurological examination its belly is tapped to elicit tarsal flexion (cranial tibial reflex), which tests the fibular nerve.
In feline aortic thromboembolism this muscle and the gastrocnemius become firm and painful from ischaemia.
