We are interested only in skeletal and muscular systems in this course

Skeletal SystemCartilage

• support soft tissues • provide a smooth, gliding surface for

bone articulations at joints • enable the development and growth of

long bones Bone

• supportive structures for the body • protectors of vital organs • levers on which muscles act to

produce movement • reservoirs of calcium and phosphorus • containers for blood-producing cells

Skeletal SystemJoint

• synovial joint • solid joint

Ligament and Tendon

Medical Terminology
