What is the primary function of the Cranium?
The skull bone called Cranium protects the brain against external influences. The cranial bones are rigid and act as a helmet. It protects the eyes, nose and other sense organs. It covers the thin membrane called the meninges, which protects the brain.

Where is the cranium located?
Occipital bone: the bone that forms the back of the head and connects with the occipital condyles and foramen magnum — skeletal structures located on the underside of the skull, near the spine — and the lambdodial suture, which is at the back of the skull. Parietal bone: the main side of the skull.
What is the cranium made of?
The brain, which performs these various functions, is protected by a part of the skull called the cranium. We'll turn our attention to the eight bones that form it: the ethmoid bone, the sphenoid bone, the frontal bone, the occipital bone, two parietal bones, and two temporal bones.
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.

What part of the brain is the cranium?
The neurocranium is the upper back part that forms the protective case around the brain. The skull cap of the neurocranium covers the cranial cavity and the remainder of the skull is called the facial skeleton. The skull (minus the mandible) is also known as the cranium, and contains the brain.
How does the cranium 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. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles. These bones protect the spinal cord.
How does the cranium work?
The human skull is the bony structure that forms the head in the human skeleton. It supports the structures of the face and forms a cavity for the brain. Like the skulls of other vertebrates, it protects the brain from injury. The upper areas of the cranial bones form the calvaria (skullcap).

How does the skull grow?

What are the three types of skulls?
Due to the difference in the cranial index, scientists classified the human skulls into 3 main types- Caucasoid(European), Mongoloid(Asian), Negroid(African).
What is a joint in the cranium called?

Each has two surfaces and four borders.Are cranial bones fused?
Craniosynostosis (kray-nee-o-sin-os-TOE-sis) is a birth defect in which one or more of the fibrous joints between the bones of your baby's skull (cranial sutures) close prematurely (fuse), before your baby's brain is fully formed. Brain growth continues, giving the head a misshapen appearance.
What is your cranium?
