Define the term joint, or articulation
|
An articulation or joint is a point of contact between bones
|
|
|
List the three major classes of joints according to both a structural and a functional scheme
|
Structural classification: fibrous, cartilaginous, & synovial. Functional: synarthroses, amphiarthroses, and diarthroses
|
|
|
Name the three types of fibrous joints and give one example of each.
|
Syndesmoses: joint between distal ends of the radius and ulna. Sutures: found only in skull. Gomphoses: between the tooth and the alveolar process of the mandible or maxilla
|
|
|
Identify the two types of cartilaginous joints and give one example of each.
|
Synchondroses: betwn the 1st rib & sternum & the joint present during the growth years betwn the epiphysis of a long bone & its diaphysis. Symphyses: symphysis pubis & the articulation betwn the bodies of adjacent vertebrae
|
|
|
List the seven structures that characterize synovial joints.
|
Joint capsule, synovial membrane, articular cartilage, joint cavity, menisci, ligaments, and bursae
|
|
|
Name the 3 main categories of synovial joints grouped according 2 axial movement & list the 2 subtypes of joints found in each category.
|
Uniaxial joints: hinge & pivot joints. Biaxial joints: saddle & condyloid joints. Multiaxial joints: ball &socket & gliding joints
|
|
|
Which joint is the largest, most complex, and most frequently injured in the body?
|
Knee joint
|
|
|
List the two anatomical components of an intervertebral disk.
|
Fibrous tissue and fibrocartilage
|
|
|
Amphiarthroses -
|
slightly movable joint such as the one that connects the two pubic bones
|
|
|
Bursa -
|
small, cushion-like sacs found between moving body parts, making movement easier
|
|
|
Diarthroses –
|
freely moving joint
|
|
|
Joint -
|
junction between two or more bones; articulation
|
|
|
Menisci –
|
articular cartilage disk
|
|
|
Suture -
|
immovable joint, such as those between the bones of the skull
|
|
|
Symphysis -
|
joint characterized by the presence of a pad or disk of fibrocartilage connecting the two bones
|
|
|
Synarthroses -
|
joint in which fibrous connective tissue joins bones and holds them together tightly; commonly called sutures
