At birth, a baby’s skull is not a single, solid bone but a collection of flexible plates that allow for rapid brain growth. The fascinating **squiggly lines on a human skull** are actually these movable joints, known as cranial sutures, that eventually fuse together to form a protective helmet.

The human skull is a surprisingly complex structure, with its solidity being a defining feature of adulthood. However, the question, "What's the softest part of your skull?" can only be answered by looking at the earliest stages of life when the skull is not yet fully fused.

The average newborn has six fontanelles, commonly known as soft spots, on their head. For new parents, finding these gaps can be startling, but it is completely normal to have soft spots on the skull. They are crucial for a baby's healthy development.
