Functional Classification of Joints Synarthroses – immovable joints

Example: Sutures of the skull

Amphiarthroses – slightly moveable joints Example: Vertebral column

Diarthroses – freely moveable joints Example: Knee, elbow, shoulder

Structural Classification of Joints

Fibrous joints: connected by thin layer of tissue Generally immovable Sutures of the skull

Cartilaginous joints: connected bywhite cartilaginous disks Immovable or slightly moveable Pubis Symphasis, Vertebrae

Synovial joints: connected by smooth articular cartilage, attached by ligaments Freely moveable Knee, elbow, shoulder

Fibrous Joints

Bones united by fibrous tissue Examples

Sutures Syndesmoses

Allows more movement than sutures

Example: distal end of tibia and fibula

Cartilaginous Joints

Bones connected by cartilage

Examples Pubic symphysis Intervertebral joints

Synovial Joints

Articulating bones are separated by a joint cavity

Synovial fluid is found in the joint cavity

Features of Synovial Joints

Articular cartilage (hyaline cartilage) covers the ends of bones

Joint surfaces are enclosed by a fibrous articular capsule

Have a joint cavity filled with synovial fluid

Ligaments reinforce the joint

Structures Associated with the Synovial Joint

Bursae – flattened fibrous sacs Lined with synovial membranes Filled with synovial fluid Not actually part of the joint

Tendon sheath Elongated bursa that wraps around a

tendon

Inflammatory Conditions Associated with Joints

Bursitis – inflammation of a bursa usually caused by a blow or friction

Tendonitis – inflammation of tendon sheaths

Arthritis – inflammatory or degenerative diseases of joints

Over 100 different types The most widespread crippling disease in the

United States

Page 18: The Skeletal System Joints. Joints Articulations of bones Functions of joints Hold bones together Allow for mobility Ways joints are classified.

Clinical Forms of Arthritis

Osteoarthritis Most common chronic arthritis Probably related to normal aging processes

Rheumatoid arthritis An autoimmune disease – the immune

system attacks the joints Symptoms begin with bilateral

inflammation of certain joints Often leads to deformities

Clinical Forms of Arthritis

Gouty Arthritis Inflammation of joints is caused by a

deposition of urate crystals from the blood Can usually be controlled with diet

JOINTS & Articulations. Joints occur where 2 bones meet. They may: join two bones with as little flexibility as possible join two bones with a little.
