Study Notes
Anatomy of Joints
- Articulation is the connection between two or more bones.
- Joints are classified into three types based on the tissue between bones: fibrous, cartilaginous, and synovial.
Fibrous Joints
- Connected by fibrous tissue.
- Little to no movement.
- Types:
- Sutures: Immovable joints found between bones of the skull (fuse over time).
- Gomphoses: Joints between the roots of teeth and their sockets.
- Syndesmoses: Joints connected by strong ligaments (e.g., distal tibiofibular joint).
Cartilaginous Joints
- Connected by cartilage.
- Limited movement.
- Types:
- Primary cartilaginous joints (Synchondroses): Bones connected by hyaline cartilage (e.g., 1st sternocostal joint, epiphyseal plate of long bones).
- Secondary cartilaginous joints (Symphyses): Connected by fibrocartilage (e.g., intervertebral discs, symphysis pubis).
Synovial Joints
- Freely movable.
- Surrounded by a fibrous capsule lined with a synovial membrane that produces synovial fluid.
- Articular surfaces covered with articular cartilage.
- Types are classified by:
- Number of articulating bones: Simple (2 bones), Compound (more than 2), Complex (intra-articular disc or menisci).
- Axes of movement: Uni-axial (one axis), Bi-axial (two axes), Poly-axial (more than two axes).
- Shape of articulating bones: Plane, Hinge, Pivot, Ellipsoid, Bi-condyloid, Saddle, Ball & socket.
- Structures inside synovial joints:
- Cartilage: Discs (e.g. temporomandibular joint), Menisci (e.g. knee joint), Labrum (e.g. hip, shoulder joints).
- Ligaments: Cruciate ligaments in knee (ACL, PCL), Tendons of muscles like the long head of biceps in shoulder joint.
- Factors affecting joint stability:
- Articulating bones' shape and size
- Arrangement of surrounding muscles
- Strength and position of ligaments
- Nerve supply to a muscle also innervates joint it acts on and surrounding skin (Hilton's Law).
