It includes the skull, vertebral column, ribs, and sternum. Its primary func?on is protec1on of vital organs such as the brain, heart, and lungs, and to provide structural support for the body. -The appendicular skeleton includes all the bones of the limbs (arms and legs), as well as the shoulder girdle and pelvis. This part of the skeleton is mainly responsible for movement, allowing us to walk, run, liC objects, and carry out daily tasks. The longest bone in the human body, the femur, is located in the appendicular skeleton. Notas • Axial = centro, protege. • Appendicular = extremidades, movimiento. • Femur = hueso más largo. Functions of the Skeleton The skeleton performs several essen?al func?ons: A. Support Bones form a rigid framework that supports the soC ?ssues of the body. B. Protec1on Important organs are safely enclosed: the cranium protects the brain, and the rib cage protects the heart and lungs. C. Movement Bones act as levers. Muscles are aKached to bones and contract to produce movement. D. Miner...
