Arthrology – the study of joints Kinesiology – the study of motion of the
human body
Functional ClassificationsSynarthroses (immovable)Amphiarthroses ( partially movable)Diarthroses (freely movable)
Structural ClassificationFibrousCartilaginousSynovial
Synovial FluidSynovial Fluid
Synovial fluid consists of: Hyaluronic acid Interstitial fluid from plasma
Functions of synovial fluid Lubrication Reduce friction between structures Supply nutrients Remove waste products Phagocytosis of microbes & debris
Movement at jointsMovement at joints
Structure & Shape of Bones Involved Strength & Tension of Ligaments Arrangement & Tension of MusclesOpposing Soft Parts Hormones Disuse
Learning ObjectivesLearning Objectives

Describe the factors that affect movement at synovial joints
Describe the different types of movement of joints (be able to give examples)
