BIOL 003 Lecture Notes - Lecture 9: Synovial Joint, Hyaline Cartilage, Synovial Fluid
Document Summary
Increasing angle between bones (e. g. flexion/extension of elbow joint) Movement towards median plane of body (e. g. lowering arms to side of body) Movement away from median plane of body (e. g. raising arms to point away from the sides of body) Describe the joints of the axial and appendicular skeleton and the structure of synovial joints. Bones joined by cartilage (e. g. between adjacent vertebra, between ribs and sternum) Capsule surrounding articulating bones w/ synovial fluid (e. g. knee, elbow) Movement in one plane (e. g. knee, elbow joints) Rotation around a single axis (e. g. axis/atlas nodding no // radius/ulna) Articular surfaces glide over one another (e. g. intercarpal/intertarsal joints) Movement in all planes (e. g. shoulder joint (scapula/humerus) and hip joint (coxal bone/femur) Explain how muscle action causes movement at joints and define an antagonistic muscle pair. Complex array of ligaments, muscles and tendons cover and cross over joints = vast amount of joint movements!
