This document provides an overview of the human skeletal system, describing the main bones and structures of the axial skeleton including the skull, vertebrae, ribs, and pelvis, as well as the appendicular skeleton including the pectoral girdle, upper limbs, pelvis, and lower limbs. Key bones that are discussed include the skull bones like the sphenoid, vertebrae of the neck, thorax and lumbar spine, ribs, sternum, clavicle and scapula, humerus, hand bones, and bones of the feet. The skeletal system provides structure, support, and protection for the body.
