Study Notes

Joint Classification Overview

Articulation refers to joints, where two bones connect, or where bones meet cartilage or teeth.

Criteria for Structural Classification

Structural classification is based on:
- Presence of a synovial cavity, reflecting the space between articulating bones.
- Type of connective tissue binding the bones together.

Types of Structural Classifications

Fibrous Joints:
- No synovial cavity is present.
- Bones connected by dense irregular connective tissue rich in collagen fibers.
Cartilaginous Joints:
- Lack a synovial cavity.
- Bones united by cartilage.
Synovial Joints:
- Characterized by the presence of a synovial cavity.
- Bones held together by dense irregular connective tissue of an articular capsule, potentially supported by accessory ligaments.

Functional Classification of Joints

Refers to how joints facilitate movement, classified into:
- Synarthrosis:
  - Immovable joints.
- Amphiarthrosis:
  - Slightly movable joints.
- Diarthrosis:
  - Freely movable joints.
