where is the dorsum of the foot located
Sole (foot) In the fourth layer. the dorsal and plantar interossei are located between and below the metatarsal bones and act as antagonists.[2]
Foot The instep is the arched part of the top of the foot between the toes and the ankle.
Cuboid bone In the human body, the cuboid bone is one of the seven tarsal bones of the foot.
Foot The human foot has two longitudinal arches and a transverse arch maintained by the interlocking shapes of the foot bones, strong ligaments, and pulling muscles during activity. The slight mobility of these arches when weight is applied to and removed from the foot makes walking and running more economical in terms of energy. As can be examined in a footprint, the medial longitudinal arch curves above the ground. This arch stretches from the heel bone over the "keystone" ankle bone to the three medial metatarsals. In contrast, the lateral longitudinal arch is very low. With the cuboid serving as its keystone, it redistributes part of the weight to the calcaneus and the distal end of the fifth metatarsal. The two longitudinal arches serve as pillars for the transverse arch which run obliquely across the tarsometatarsal joints. Excessive strain on the tendons and ligaments of the feet can result in fallen arches or flat feet.[6]
