General Anatomy for Public Health - Practical 3: Joints

A joint is the point where two or more bones meet.
Joints are categorized by the material (tissue) separating the bones: fibrous, cartilaginous, and synovial.
Fibrous joints: Bones connected by fibrous tissue; no movement.
- Examples: sutures of the skull, gomphosis (teeth in jaw sockets), syndesmosis (tibio-fibular joint).
Cartilaginous joints: Bones connected by cartilage; limited movement.
- Subtypes:
  - Primary (synchondrosis): Temporary cartilage between bones; no movement (e.g., epiphyseal plates in long bones).
  - Secondary (synchondrosis): Permanent cartilage between bones; limited movement (e.g., intervertebral discs, pubic symphysis).
Synovial joints: Have a special structure; range of movement.
- Classified by the number of axes of movement: uniaxial, biaxial, polyaxial, plane.
  - Uniaxial: One axis of movement (e.g., hinge, pivot).
  - Biaxial: Two axes of movement (e.g., condyloid, saddle).
  - Polyaxial: Multiple axes of movement (e.g., ball and socket).
  - Plane: Gliding movement (e.g., intercarpal).
Factors affecting joint stability:
- Bony structure, surrounding muscles, ligaments.
