Here's a breakdown:
* Joint: A place where two or more bones meet.
* Cartilaginous: Made of cartilage, a strong, flexible connective tissue.
In a symphysy, the ends of the bones are covered in hyaline cartilage and are connected by fibrocartilage. This type of joint allows for limited movement but provides stability and support.
Here are some examples of symphyses in the body:
* Pubic symphysis: Connects the two halves of the pelvis. This joint allows for some flexibility during childbirth.
* Manubriosternal joint: Connects the manubrium (top part) of the sternum (breastbone) to the body of the sternum.
* Intervertebral discs: These are technically not "symphyses" but are similar in structure and function, connecting the vertebrae of the spine.
In summary, a symphysy is a type of joint that provides both stability and limited movement, thanks to its cartilage structure.
