A limb is an anatomical term that refers to the appendages or extremities of the human body, including the arms and legs. These structures provide mobility, dexterity, and support for various physical activities. The limbs are composed of bones, muscles, tendons, and joints that work together to facilitate movement and perform tasks such as grasping, walking, running, and manipulating objects. Each limb consists of several segments, such as the upper arm, forearm, hand, thigh, leg, and foot. The limbs are vital for locomotion, balance, and interaction with the surrounding environment, playing a crucial role in daily activities and overall physical function.
