Document Summary
The bones of the skeleton come in a variety of shapes and sizes and must be strong yet relatively lightweight. Bones protect soft body parts and make movement possible; they also serve as landmarks for locating parts of other body systems. The musculoskeletal system is composed of the bones, joints, and muscles working together. Fissure - narrow slit between adjacent parts of bones through which blood vessels or nerves pass. Sulcus - furrow along a bone surface that accommodates a blood vessel, nerve, or tendon. Condyle - large, round protuberance at the end of a bone. Head - rounded articular projection supported on the neck (constricted portion) of a bone. Line - long, narrow ridge or broader (less prominent than a crest) The axial skeleton consists of bones arranged along the longitudinal axis. The parts of the axial skeleton are the skull, auditory ossicles (ear bones), hyoid bone, vertebral column, sternum, and ribs.
