Document Summary
Human body is composed of 11 major body parts that are located within the axial and appendicular portions of the body. Some of the major body parts are comprised of smaller parts separated from each other by joints. True movement of a body part involves movement of that body part relative to another body part at the joint located between them. Skeletal system: external functions, structural support of body, provide levers for body movement, protection of underlying structures, internal functions, blood cell production, fat storage within yellow marrow, storage of miners (calcium and phosphorus) Bones are organic, living structures, that are highly enervated with both sensory and motor neurons. They require a rich supply of blood in order to continue the process of regenerating new body tissue significance of long bones: site for bone marrow and rbc production and storage. Involved in articulations at many of the bodies joints.
