Answer 1

The bones of the skull can be divided into those of the cranium and those of the face. The vault is the upper part of the cranium, and the base of the skull is the lowest part of the cranium.

The skull bones are made up of external and internal tables of compact bone separated by a layer of spongy bone called the diploe. The internal table is thinner and more brittle than the external table. The bones are covered on the outer and inner surfaces with periosteum.

Answer 2

Answer:

Option A is the correct answer.

Explanation:

The bones that make up the head. The skull is composed of cranial bones (which surround and protect the brain) and facial bones (bones that form the eye sockets, nose, cheeks, jaw, and other parts of the face. The spinal cord links to the brain through a hole at the base of the skull. Also known as the cranium.

              The skull (also known as the cranium) is made up of 22 bones that are separated into 8 cranial bones and 14 facial bones. The bones of the skull are classified as cranium bones and facial bones.

              The vault is the upper half of the cranium, whereas the base of the skull is the lower part. The skull bones are composed of external and internal compact bone tables separated by a spongy bone layer known as the diploe. The inside table is more fragile and thinner than the outward table. The periosteum covers the outer and interior surfaces of the bones.

The major purpose of the skull bones and the surrounding meninges is-

• To provide protection and structure.

• The skull's purpose is both structurally supporting and defensive.

• During development, the skull will harden and fuse to preserve its inner contents: - the cerebrum, cerebellum, brainstem, and orbits.
