Chapter 8 Flashcards
Three structural types of joints
Fibrous, Cartilaginous, Synovial
Three functional classifications of joints
Synarthroses, Amphiarthroses, Diarthroses
Immovable joints
Synarthroses
Slightly movable joints
Amphiarthroses
Freely movable joints
Diarthroses
Most are synarthroses, bones joined by connective tissue fibers
Fibrous joints
Three types of fibrous joints
Sutures, Syndesmoses, Gomphoses.
Some are amphiarthrodial and some are synarthrodial
Cartilaginous
A form of Cartilaginous, Synarthrotic with hyaline cartilage
Synchondrosis
A form of Cartilaginous, Amphiarthrotic with fibrocartilage
Symphysis
All Synovial joints are ______ and separated by ________
Diarthrotic. Fluid-filled joint cavity.
Six general features of Synovial Joints
Articular cartilage, joint cavity, articular capsule, synovial fluid, different types of reinforcing ligaments, nerves and blood vessels.
Six different types of synovial joints
Plane, Hinge, Pivot, Condylar, Saddle, Ball-And-Socket
_______ is the attachment to movable bone
Insertion
______ is the attachment to immovable bone
Origin
The four rotator cuff tendons that encircle the shoulder joint
Subscapularis, Supraspinatus, Infraspinatus, Teres Minor
Tendon of long head of biceps brachii muscle is known as a _______. It travels through the ________ and secures the humerus to the ______
Superstabilizer. Intertubercular sulcus. Glenoid Cavity
Reinforcing ligaments are stretched or torn
Sprains
Bones forced out of alignment
Disclocation/Luxation
Partial dislocation of a joint
Subluxation
Inflammation of Bursa, caused by blow or friction
Bursitis
Inflammation of Tendon sheaths, caused by overuse
Tendonitis
Three chronic forms of arthritis
Osteoarthritis, Rheumatoid Arthritis, Gouty Arthritis
Most common type of arthritis, irreversible and degenerative
Osteoarthritis. Ostephytes (bone spurs) may form from thickened end of bones
Immune system attacks the synovial joints
Rheumatoid Arthritis
Excess Uric Acid crystalizes and deposits in joints.
Gouty Arthritis
