Anatomy and Physiology: The Unity of Form and Function (Chapter 9: Joints) Questions And Answers A+

Anatomy and Physiology: The Unity of Form and Function (Chapter 9: Joints) Questions And Answers A+ Joint (articulation) - ANS-Any point where two bones meet, whether or not the bones are movable at that interface Arthrology - ANS-The science of joint structure, function and dysfunction Kinesiology - ANS-The study of musculoskeletal movement Biomechanics - ANS-Deals with a broad variety of movements and mechanical processes in the body, including the physics of blood circulation, respiration and hearing Bony Joint (synostosis) - ANS-Immovable joint formed when the gap between two bones ossifies and they become a single bone fused by osseous tissue. Includes frontal bone, mandible and epiphyseal plate Fibrous Joint (synarthrosis or synarthrodial joint) - ANS-Point at which two adjacent bones are bound by collagen fibers that emerge from one bone, cross the space between them, and penetrate into the other with variable degrees of mobility. Includes skull sutures, tooth sockets and interosseous membrane in the radius and ulna Cartilaginous (Amphiarthrosis or amphiarthrodial) Joint - ANS-Two bones joined by cartilage that allows for little motion but retains a significant amount of stability. Includes pubic symphysis and intervertebral disc. (Syndochondrosis if hyaline; symphysis if fibrocartilage) Synovial (diarthrodial) Joint (diarthrosis) - ANS-A joint in which the opposing bone surfaces are covered with hyaline cartilage or fibrocartilage and there is some degree of free movement and are separated by a space filled with synovial fluid. Includes shoulder, elbow, hip, knee and knuckles Articular Cartilage - ANS-Thin hyaline cartilage layer that covers epiphyses or articular surface of bones in synovial joints Synovial Fluid - ANS- CONTINUES...
