This document provides an overview of functional anatomy and the musculoskeletal system. It discusses the key structures including bones, joints, muscles, planes of movement, and anatomical terminology. Bones provide structure, protection and movement. The 206 bones in the human body are divided into the axial skeleton along the midline and appendicular skeleton in the limbs. Synovial joints allow movement and are connected by ligaments and tendons. Muscles have three main functions - movement, posture and heat production - and are either skeletal, cardiac or smooth muscle. Skeletal muscle is composed of striated muscle fibers that run from origin to insertion points.
