How Do You Spell THORACIC LIMB?

1. A thoracic limb is one of the four limbs or appendages in mammals, situated in the area of the thorax or chest. It is commonly referred to as the front limb or forelimb. This limb is specifically found in animals with a well-developed bony structure, such as mammals, and plays a crucial role in locomotion, stability, and manipulation.

   The thoracic limb consists of several key components including the upper arm (brachium), forearm (antebrachium), wrist (carpus), palm (metacarpus), and digits (fingers). The upper arm is connected to the torso through the shoulder joint and houses the major bones, namely the humerus. The forearm, adjacent to the upper arm, is composed of two bones, the radius and the ulna. The wrist, located at the distal end of the forearm, contains a cluster of small bones called the carpal bones. The palm consists of the metacarpal bones, which extend from the wrist to the base of the fingers. Finally, the digits or fingers are comprised of bones known as phalanges.

   The thoracic limb is responsible for a wide range of functions, including weight-bearing, jumping, climbing, digging, and manipulating objects. It is an essential anatomical feature that facilitates numerous activities required for survival and adaptation in various environments.
