General
- This page summarizes all the bony articulations of the human body
- It also summarizes the types of joint by structure and function
Joint Anatomy
By Structure
- Fibrous Joints: Bones are joined by dense connective tissue; no movement
- Examples: skull sutures
- Cartilaginous Joints: Bones are connected by cartilage; limited movement
- Examples: spine, ribs, pubic symphysis
- Synovial Joints: Most common; freely movable joints with a synovial cavity
- Examples: knee, shoulder
By Function/ Degree of Movement
- Synarthrosis: Immovable
- Example: skull
- Amphiarthrosis: Slightly movable
- Example: intervertebral discs
- Diarthrosis: Freely movable
- All synovial joints
Types of Synovial Joints
- Hinge: Allows bending and straightening (e.g., elbow, knee)
- Ball-and-Socket: Multidirectional movement and rotation (e.g., shoulder, hip)
- Pivot: Rotational movement around a single axis (e.g., neck)
- Saddle: Movement in two directions (e.g., thumb)
- Condyloid (Ellipsoidal): Movement but no rotation (e.g., wrist)
- Gliding (Plane): Sliding or gliding movements (e.g., between tarsal bones)
Joints of the Body
- Intercarpal Joints
- Carpometacarpal Joints
- Metacarpophalangeal Joints
- Proximal interphalangeal Joints
- Distal interphalangeal Joints
- Distal Tibiofibular Joint
- Ankle joint
- Subtalar Joint
- Transverse Tarsal Joint
- Tarsometatarsal joints
- Metatarsophalangeal Joints
- Proximal and Distal Interphalangeal Joints
