Document Summary
Objectives joints: structure and function: diff types of joints, characteristics of a typical synovial joint, characteristics of the shoulder joint, characteristics of the hip joint, characteristics of the knee joint. Joint point at which 2 bones articulate w each other. Joints vary greatly in structure and function: degree, range, and direction of movement at a joint = determined by structure of the joint. Classification of joints (low mobility to high mobility: fibrous immovable (synarthroses, connected by fibrous tissue, ex. sutures, tibiofibular joint, socket of tooth, cartilaginous slightly movable (amphiartroses, hyaline cartilage (ex. epiphyseal growth plate, fibrocartilage (ex. Pubic symphysis, intervertebral discs: synovial highest degree of mobility (diarthroses, mainly found in appendicular skeleton, fibrous joints immovable. During development bones separated by short collagen fibres. With age fibrous tissue ossifies, bones become fused. Intercarpal bones of hand: hinge joints (pic 1) Cylindrical end of 1 bone articulates w trough of another.
