What is an example of a limb?

A common example of a limb is the human arm, and another example is a bird’s wing.

In everyday language, a “limb” is a part that sticks out from the main body and helps with movement or function. In humans and many animals, limbs are the arms and legs. These parts allow walking, grasping, climbing, swimming, or flying depending on the species. For plants, the term “limb” is not standard in biology, but people sometimes use “limb” to refer to a large tree branch in casual speech. The core idea is that a limb is an extended part used for actions like moving or handling things.

Human and animal limb examples

• Human arm: Used for reaching, lifting, writing, and tool use.
• Human leg: Used for standing, walking, running, and balance.
• Cat forelimb and hindlimb: Used for walking, jumping, and grooming.
• Bird wing: A modified forelimb used for flight and balance.
• Whale flipper: A modified forelimb used for swimming and steering.
• Frog hindlimb: Long and strong, used for powerful jumps and swimming.

Key features that make something a limb

• Attachment: It connects to the main body or trunk.
• Segments: It often has segments (for example, upper arm, forearm, hand).
• Joints: It usually bends at joints to increase range of motion.
• Function: It supports movement, grasping, flight, or swimming.

Quick check: If it sticks out from the body and helps the organism act on the world, it is likely a limb.
