What type of joint is the elbow joint?*1 pointFibrousSynovial ball and socketCartilaginousSynovial hinge joint

Break Down the Problem

1. Identify the types of joints mentioned in the question.
2. Understand the specific characteristics of each joint type.
3. Determine the type of joint that best describes the elbow joint.

Relevant Concepts

1. Fibrous joints: These joints are connected by dense connective tissue and are typically immovable (e.g., sutures in the skull).
2. Synovial ball and socket joints: These allow for rotational movement in multiple directions (e.g., shoulder and hip joints).
3. Cartilaginous joints: These joints are connected entirely by cartilage and allow for limited movement (e.g., the joints between vertebrae).
4. Synovial hinge joints: These joints allow movement primarily in one plane, enabling flexion and extension (e.g., the elbow and knee joints).

Analysis and Detail

• The elbow joint connects the humerus (upper arm bone) with the radius and ulna (forearm bones).
• Its structure allows for flexion and extension, making it a hinge joint.

Verify and Summarize

Given that the elbow joint allows movement primarily in one direction (flexion and extension), it aligns with the description of a synovial hinge joint.

Final Answer

The elbow joint is classified as a Synovial hinge joint.
