Understand the definition of symphyses: Symphyses are a type of cartilaginous joint where bones are connected by fibrocartilage. These joints are designed to provide both strength and flexibility.
Review the classification of joint movement: Joints are classified based on their movement as synarthrotic (immovable), amphiarthrotic (slightly movable), or diarthrotic (freely movable). Symphyses fall under the amphiarthrotic category.
Eliminate incorrect options: Symphyses are not synarthrotic joints (immovable), nor are they diarthrotic joints (freely movable). Additionally, symphyses are not fibrous joints, which are typically found in the skull (e.g., sutures).
Focus on the correct description: Symphyses are amphiarthrotic joints that provide strength with flexibility, allowing limited movement while maintaining structural integrity.
Confirm the correct answer: Based on the characteristics of symphyses, the correct statement is 'Symphyses are amphiarthrotic joints that provide strength with flexibility.'
