What is the Difference Between Limbs and Legs of Vertebrates?
In the animal kingdom, vertebrates possess limbs that allow them to move and navigate their surroundings. Limbs are appendages that extend from the body and are typically supported by bones. While the terms "limb" and "leg" are often used interchangeably, there are distinct differences between the two.
Definition
- Limb: A general term for any appendage that extends from the body and is used for locomotion or other functions.
- Leg: A specific type of limb that is used for walking, running, or supporting the body's weight.
Structure
Limbs can vary greatly in structure and function depending on the species. They may be long and slender, as in the case of snakes, or short and robust, as in the case of elephants. Legs, on the other hand, are typically longer and more muscular than other types of limbs. They consist of a femur (thigh bone), tibia and fibula (lower leg bones), and foot.
Function
Limbs serve a variety of functions, including locomotion, grasping, and defense. Legs are specifically adapted for walking and running. They provide stability and allow vertebrates to travel over extended distances. The muscles, joints, and bones of the leg work together to facilitate movement, while the foot provides traction and shock absorption.
