Where does the tibialis anterior attach?
The junction between the medial cuneiform and base of 1st metatarsal
Where does the fibularis longus attach?
Tendon passes across plantar aspect of the foot to attach to medial cuneiform and base of 1st metatarsal
What bones from the lateral longitudinal arch?
Calcaneus, cuboid and metatarsals 4&5
What bones form the transverse arch?
