How can you explain that there are different types of bone connection in the human skeleton?

The type of bone connection depends on the function.

1. Where protection is required, bones are rigidly connected. For example:
the bones of the cerebral part of the skull protect the brain;
the pelvic bones protect the bladder and uterus in women.
2. Where movement is required, bones connect:
semi-mobile – with the help of cartilage. This is how the vertebrae are connected. which allows us to bend over. The ribs are also connected to the sternum. which allows breathing movements.
movably – with the help of joints: the connection of the bones in the limbs.
