Similarly, why are there so many bones in the cranium? It is made of many bones that fit together tightly, to protect the brain and support the face. The upper part of the skull is like a helmet that surrounds the brain. This makes the skull very strong. Babies have spaces between the cranial (skull) bones so that their heads can withstand being squashed as they are born.

How does bone protect the brain?

The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. It runs down from the brain through a canal in the center of the bones of the spine. These bones protect the spinal cord.

What is the smallest bone in the body?

What joins bone to bone?

A ligament is the fibrous connective tissue that connects bones to other bones. Ligaments are similar to tendons as they are all made of connective tissue. The differences in them are the connections that they make. Ligaments connect one bone to another bone while the tendons connect muscle to bone.

How many frontal bones are in the skull?

The frontal bone is a bone of the skull found in the forehead region. It is one of eight bones that form the cranium, or brain case. The frontal bone plays a vital role in supporting and protecting the delicate nervous tissue of the brain. It gives shape to the skull and supports several muscles of the head.

Why are bones so strong?

Bones provide support for our bodies and help form our shape. Bones are made up of a framework of a protein called collagen, with a mineral called calcium phosphate that makes the framework hard and strong.
