9-2 Joints and Their Classification Arthrology = study of the joints Kinesiology = study of musculoskeletal movement Classified by freedom of movement diarthrosis (freely movable) amphiarthrosis (slightly movable) synarthrosis (little or no movement) Classified how adjacent bones are joined fibrous, cartilaginous, bony or synovial
Image of page 2
Joints! 3 types of joints if we classify by function (i.e., by the degree of movement possible): 1. Diarthroses Freely moveable joints Shoulder, knee, hip, elbow, interphalangeal, tarsal, and carpal joints 2. Amphiarthroses Slightly moveable joints Intervertebral discs, costosternal joints, pubic symphysis 3. Synarthroses Joints with little or no movement Skull sutures, mental symphysis, teeth in sockets, 1 st costosternal joint.

Joint Classification We can also classify joints by structure: 1. Synovial joints : Bones separated by a joint cavity; lubricated by synovial fluid; enclosed in a fibrous joint capsule. Shoulder, hip, elbow, knee, carpal, interphalangeal How would we classify these joints functionally?
Image of page 4
Joint Classification 1. Fibrous joints : Bones held together by collagenous fibers extending from the matrix of one bone into the matrix of the next. No joint cavity Skull sutures, teeth in joints, distal radioulnar joints & tibiofibular joints

Joint Classifications 1. Cartilaginous joints : Bones held together by cartilage; no joint cavity Epiphyseal plates of long bones, costosternal joints, pubic symphysis , intervertebral discs

9-9 Cartilaginous Joint -- Synchondrosis Bones are joined by hyaline cartilage rib attachment to sternum epiphyseal plate in children binds epiphysis and diaphysis

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
