What is a Description of the Appendicular Skeleton?
The appendicular skeleton is the portion of the skeletal system that consists of the bones of the limbs and the structures that connect them to the axial skeleton. It includes the bones of the upper and lower limbs, as well as the pectoral and pelvic girdles that attach them to the axial skeleton.
The appendicular skeleton is responsible for movement, providing support and protection for the muscles and internal organs. It also allows for a wide range of motion, including walking, running, jumping, and throwing. The bones of the appendicular skeleton are divided into two main sections: the upper limb and the lower limb.
The upper limb includes the bones of the arm, forearm, and hand. The arm bone is called the humerus, the forearm bones are the radius and ulna, and the hand bones are the carpals, metacarpals, and phalanges.
The lower limb includes the bones of the thigh, leg, and foot. The thigh bone is called the femur, the leg bones are the tibia and fibula, and the foot bones are the tarsals, metatarsals, and phalanges.
The appendicular skeleton is a complex and important part of the human body, providing support, protection, and mobility.
