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. Send me the next one 📸
