20. Characteristics of the Musculoskeletal System Made up of muscles, bones, and joints Body has 206 bones and 600+ muscles Joints are located any place 2+ bones meet Functions of muscular system => movement, posture, joint stability, and heat production Functions of skeletal system => provide a framework for body, protect soft body parts (ex brain), store calcium, and produce blood cells List of structures and bones on pp.608-612 Joints hold our bones together and make movement (p.614) Muscles – skeletal, smooth, cardiac (p. 615-618)
