Study Notes
Structural Classification of Joints
- Types include fibrous, cartilaginous, and synovial.
Functional Classification of Joints
- Types include synarthroidial (immovable), amphiarthrodial (semi-movable), and diarthrodial (freely movable).
Types of Fibrous Joints
- Comprise syndesmosis, suture, and gomphosis.
Fibrous Joints
- Connect bones with a thin layer of dense connective tissue rich in collagen fibers.
Cartilaginous Joints
- Link bones via hyaline cartilage or fibrocartilage.
Synovial Joints
- Characterized by articulating ends of bones enclosed by a joint capsule, with ends covered by hyaline cartilage and separated by synovial fluid.
Kinds of Cartilaginous Joints
- Include synchondrosis and symphysis.
Syndesmosis Joint
- Bones are bound by an interosseous ligament, allowing flexibility and limited twisting movements (e.g., tibiofibular articulation).
Suture Joint
- Flat bones interconnected by sutural ligament, exhibiting no movement (e.g., parietal bones at sagittal suture).
Gomphosis Joint
- A cone-shaped process anchored in a bony socket via periodontal ligament, with no movement (e.g., root of tooth in mandible).
Synchondrosis Joint
- Bones united by bands of hyaline cartilage, allowing no movement (e.g., joint between epiphysis and diaphysis of long bone).
Symphysis Joint
- Features articular surfaces separated by hyaline cartilage and a fibrocartilage pad, permitting limited movement (e.g., intervertebral discs).
Ball and Socket Joint
- One bone’s ball-shaped head fits into another’s cup-shaped socket, allowing multi-axial movements (e.g., shoulder and hip joints).
Condyloid Joint
- An oval-shaped condyle of one bone fits into an elliptical cavity of another, allowing biaxial movements (e.g., metacarpal and phalanges joints).
Gliding Joint
- Articulating surfaces are flat or slightly curved, permitting minimal movement (e.g., carpals and tarsals).
Hinge Joint
- A convex surface of one bone articulates with a concave surface of another, allowing flexion and extension (e.g., elbow and knee).
Pivot Joint
- A cylindrical surface of one bone fits into a ring formed by another bone and ligament, allowing pronation and supination (e.g., radioulnar joint).
Saddle Joint
- Articulating surfaces have both concave and convex regions, allowing multi-axial movements (e.g., thumb joint).
Types of Synarthroidial Joints
- Include suture, synostosis, and gomphosis.
Suture Joint Example
- No movement, fibrous connection between skull bones.
Synostosis Joint Example
- Bones fused via osseous union (e.g., tarsal bones).
Gomphosis Joint Example
- Fibrous joint between tooth and socket, lacking movement.
Types of Amphiarthrodial Joints
- Include syndesmosis, symphysis, and synchondrosis.
Syndesmosis Joint Example
- Bone connected by a bundle of irregular connective tissue (e.g., mid radioulnar joint).
Symphysis Joint Example
- Fibrocartilage disc spans the joint, allowing limited movement (e.g., intervertebral disc).
Synchondrosis Joint Example
- Hyaline cartilage connecting bones, with no movement (e.g., epiphyseal plate).
Types of Diarthrodial Joints
- Include ball and socket, hinge, condyloid, pivot, gliding, and saddle.
Connective Tissue Composition
- Composed of cells and extracellular matrix; matrix includes ground substance and fibers.
- Ground substance dictates the consistency of connective tissue, while fibers provide strength.
