Originating from the proximal aspect of the [[Limb Bones and Cartilages - Horse Anatomy#Metacarpals and Metatarsals|third metatarsal]] (cannon) and [[Limb Bones and Cartilages - Horse Anatomy#Tarsal Bones|distal tarsal bones ]], the SL of the pelvic limb is relatively thinner and longer than that of the thoracic limb. It lies within the metatarsal groove deep to the DDFT. Continuing distally it bifurcates into two '''extensor branches''', as in the thoracic limb, which insert on the '''proximal sesamoid bones'''. Identical to in the thoracic limb, medial and lateral branches then join the long digital extensor tendon. | Originating from the proximal aspect of the [[Limb Bones and Cartilages - Horse Anatomy#Metacarpals and Metatarsals|third metatarsal]] (cannon) and [[Limb Bones and Cartilages - Horse Anatomy#Tarsal Bones|distal tarsal bones ]], the SL of the pelvic limb is relatively thinner and longer than that of the thoracic limb.
