Tarsel, also spelled "tarse", is a noun that refers to a bony skeletal structure found in the lower part of the leg or foot of various animals. Specifically, it is commonly used to describe the anatomical structure of a bird's leg. The tarsel, located between the metatarsals and the tibia, essentially serves as the bird's ankle joint.
In birds, the tarsel consists of several small bones connected by joints and is responsible for providing stability and flexibility to their legs. It plays a vital role in the bird's locomotion, enabling it to walk, hop, perch, and take flight. The tarsel bones are typically lightweight and designed to withstand the stress and strain associated with avian movements.
Outside the avian context, the term "tarsel" is occasionally used to refer to similar structures found in other animals, such as reptiles or amphibians. However, the specific morphology and composition of these structures may vary, reflecting the unique adaptations and locomotion mechanisms of different species.
The word "tarsel" is derived from the Middle French word "tersel," which, in turn, originated from the Latin word "tarsus." Overall, the tarsel is an essential component of the leg or foot anatomy, providing structural support and facilitating versatile movements in various animals, primarily birds.
