Questions and Answers

What are the two forms of joint classification?

Fibrous and cartilaginous

Synovial and fibrous

Structural and functional (correct)

Primary and secondary

Describe the difference between the structural and functional classification of joints.

Structural is based on the major connective tissue type that binds together the bones. Functional is based on the degree of motion offered by the joint.

What are the three subclasses of the structural classification of joints?

Fibrous, cartilaginous, and synovial.

Study Notes

Joint Classification Overview

Joints are classified structurally and functionally.
Structural classification is based on the connective tissue type binding bones.
Functional classification considers the degree of motion allowed by joints.

Structural Classification

Subclasses: Includes fibrous, cartilaginous, and synovial joints.

Fibrous Joints

Linked by dense regular fibrous connective tissue.
Characterized by minimal to no cartilage presence.
Do not have a joint cavity.
Permit little to no movement.
Examples include sutures in the skull and gomphoses (tooth sockets).

Cartilaginous Joints

Comprised of cartilage, with no joint cavity present.
Allow little to no movement.
Subclasses: Split into primary (hyaline cartilage) and secondary (fibrocartilage).
An example of a primary cartilaginous joint is the costalchondral joint; secondary examples include intervertebral joints.

Synovial Joints

Feature a synovial joint cavity that separates the articulating bones.
Provide free movement.
Commonly found in the appendicular skeleton.

Functional Classification

Classes: Include synarthrosis, amphiarthrosis, and diarthrosis.

Synarthrosis

Represents joints with no or restricted movement.
Examples include sutures and gomphoses.

Amphiarthrosis

Represents joints that allow some movement.
Examples include the pubic symphysis and intervertebral discs.

Diarthrosis

Represents joints that provide a broad range of movement.
Examples include the hip and knee joints.

Key Points

Fibrous and cartilaginous joints do not have a joint cavity.
Each class of joints has specific characteristics defining movement and structure.
