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.
