|
Extrinsic and Intrinsic
What are the 2 types of ligaments?
|
Symphysis (pubic symphysis) and Synchondrosis (epiphyseal plate to line)
What are the types of cartilaginous joints?
|
The pulposus of nucleus forced out from cartilage pad due to stress being pushed on one side
What is a herniated disc?
|
Acromioclavicular joint
Plane joint b/w acromion & the acromial end
|
Arthroscopy; small incision made in knee, arthroscope inserted into knee letting surgeon see area w/o having to make large incision
What is a treatment for a torn ligament?
|
|
Extracapsular (outer surface of articular capsule) and Intracapsular (within the articular capsule)
What are the 2 types of Intrinsic ligaments?
|
Syndesmosis
A fibrous joint that is considered amphiarthrosis; ulna/radius & fibula/tibia are joined by D.R connective tissue
|
The cushion is lost, as well as mobility.
What happens if you take out an intervertebral disc?
|
Acromioclavicular ligament
Gliding of the scapula on the clavicle happens here; strengthens articular capsule superiorly
|
A fat pad
What acts as packing material, provides protection for the joint, and fill spaces where bone moves?
|
|
Outside or separate from the articular capsule
Where is the Extrinsic ligament?
|
Pivot joint
1 articulating bone w/ a rounded surface fits into a ring formed by ligament & another bone. 1st bone rotates on its longitudinal axis relative to the 2nd bone
|
Gliding; plane joint
Articular facets of the superior and inferior articular processes are where what occur?
|
Coracoclavicular ligaments
The most severe type of ligament separation is?
|
Bursae
What is filled with synovial fluid and reduces friction where bones, ligaments, muscles, and tendons rub together?
|
|
Lubrication, Nourishment, Shock absorber, and Distribution of force/stress
What are the functions of synovial fluid?
|
Angular motion
Bones change with respect to each other; found in hinge joints
|
It loses it's water content, which shortens the vertebral column (decreases height); risk for injury is high
What happens to the nucleus pulposus as we age?
|
Acromioclavicular
Separation also occurs here
|
Medial, lateral, and posterior
The articular capsule of the knee joint encloses which regions of the knee joint?
|
|
The fibrous layer and the synovial membrane
What does the articular capsule consist of?
|
Linear motion
Gliding or sliding; found in uniaxial joints (plane joint)
|
Fibrocartilage
What is between intervertebral discs?
|
The glenohumeral joint; anterior, posterior, inferior, and superior
Where does dislocation occur and how?
|
Condylar joint
Oval articulating surface on 1 bone closes interacts w/ the surface of a depressed concave bone (Joystick)
