What is 2ry cartilaginous joint

A secondary cartilaginous joint, also known as a symphysis, is a type of joint where the articulating bones are covered with hyaline cartilage, and between these cartilaginous surfaces, there is a layer of fibrocartilage. These joints are slightly movable, allowing for a limited range of motion.

• Structure: They consist of two bone ends covered by hyaline cartilage. A pad of fibrocartilage is located between these hyaline cartilage layers, acting as a shock absorber and providing some flexibility.
• Mobility: They are classified as amphiarthroses, meaning they are slightly movable.
• Examples:
  • The pubic symphysis (joining the left and right pubic bones).
  • The intervertebral discs between the bodies of adjacent vertebrae in the spine.
