=='''Craniolateral Muscles of the Crus'''==

These muscles arise from the distal femur or proximal tibia or fibula. Their tendinous insertions are often multiarticular and insert on the metatarsals or phalanges. They are innervated by the '''peroneal nerve'''.

'''''Cranial Tibial (Tibialis Cranialis)'''''

:'''Origin''': Lateral condyle and tuberosity of the tibia

:'''Origin''': Lateral condyle and tuberosity of the [[Bones and Cartilages - Horse Anatomy#Tibia and Fibula|tibia]]

:'''Insertion''': Bifurcates into a medial and lateral branch. The lateral branch inserts on the metatarsal tuberosity.  The medial branch inserts on the combined first and second tarsal bones. The medial branch is also known as the '''cunean tendon'''.
