tells you what it does
The appendicular skeleton refers to the bones of the limbs and the girdles that connect them to the axial skeleton. Its major functions are:
1. Movement and locomotion: The appendicular skeleton provides a framework for the attachment of muscles. It consists of bones like the arms (humerus, radius, ulna) and legs (femur, tibia, fibula) that form the structure for movement. By working together with muscles, tendons, and ligaments, the appendicular skeleton allows us to perform various activities like walking, running, jumping, and lifting.
2. Support and stability: The appendicular skeleton provides support and stability to the body. The shoulder girdle (clavicle and scapula) and the pelvic girdle (hip bone) connect the upper and lower limbs with the axial skeleton. This connection ensures that the weight and forces generated during movement are transferred efficiently and evenly throughout the body. Additionally, the appendicular skeleton helps maintain balance and coordination while performing different tasks.
To learn about the functions of the appendicular skeleton, you can consult anatomy textbooks, online educational resources such as websites or videos, or even consult with a healthcare professional or anatomy specialist. These sources will provide in-depth information and illustrations to help you understand the role of the appendicular skeleton in movement and support.
