The top of the foot is known anatomically as the dorsum of the foot.
Understanding the Dorsum
In anatomy, the term "dorsal" is used to describe the top or back part of something. Think of the dorsal fin on a shark – it's the fin located on its back, or top side relative to the water surface. Similarly, the top surface of your foot is called the dorsum because it faces upwards when you are standing.
Anatomical Terms
- Dorsum: Refers to the top surface of the foot.
- Plantar Surface: Refers to the bottom surface (sole) of the foot.
While the dorsum is the top surface, it's important not to confuse it with the bones underneath. The reference notes that a specific bone on the top of the foot is the talus, which articulates with the tibia and fibula of the lower leg. However, the term "dorsum" specifically describes the area or surface itself.
Understanding the dorsum is key for identifying various anatomical structures, including:
- Tendons (like the extensor tendons that help lift your toes)
- Blood vessels
- Nerves
This area is often subject to specific types of injuries or conditions, such as tendonitis or pressure points from footwear.
