Study Notes
Types of Joints
- Fibrous Joint: Bones united by dense regular fibrous connective tissue
- Cartilaginous Joint: Bones united by cartilage
- Synovial Joint: Fluid-filled joint cavity separating cartilage-covered articulating surfaces of bones, enclosed within a capsule and united by ligaments
Functional Classification of Joints
- Based on the extent of movement allowed at a joint
- Three types of joints:
- Fibrous Joints: Immoveable
- Cartilaginous Joints: Slightly movable
- Synovial Joints: Freely movable
Fibrous Joints
- Three types: Gomphoses, Sutures, and Syndesmoses
- Bones united by dense regular fibrous connective tissue
- No joint cavity present
- Majority are immovable, but some allow movement depending on fiber length
Joint or Articulation
- Site where two or more bones meet
- Unites bones with each other, bones with cartilage, cartilage with cartilage, and bones with teeth
- Provides mobility and resists forces such as compression, tension, and shear stress
- Supportive structures align bones and protect from dislocation
Structural Classification of Joints
- Based on type of connective tissue binding articulating surfaces and presence of space between surfaces
- Three types: Fibrous Joints, Cartilaginous Joints, and Synovial Joints
- Structure determines function
