Plantar surface
The plantar surface of the foot refers to the bottom surface of the foot. The entire plantar surface extends from the toes to the heel and includes structures such as the metatarsals, arch of the foot, and the heel pad. The plantar surface plays a crucial role in weight-bearing, walking, and maintaining balance.
Molluscs have a ventral foot. Foot may be variously modified according to the habit of the animal and its function.
The superior surface of the foot is the top surface of the foot that faces upward when standing. It includes the tarsal bones, metatarsal bones, and phalanges of the toes. The skin on this surface is thinner and has fewer hair follicles compared to the sole of the foot. It is essential for weight-bearing and balance during activities like walking and running.
