This document summarizes the key tissues, structures, and mechanics involved in human movement. It discusses muscles, nerves, bones, cartilage, tendons, and joints. Tendons connect muscles to bones and transmit force, allowing muscles to pull on bones and create movement via joints. Joints include fibrous, cartilaginous, and synovial joints, with synovial joints being the most common and mobile. Synovial joints have articulating bone surfaces, a joint capsule, and often a meniscus or disc, allowing a variety of movements like hinging, pivoting, and ball-and-socket motions.
