Is the neurocranium the skull?

In human anatomy, the neurocranium, also known as the braincase, brainpan, or brain-pan is the upper and back part of the skull, which forms a protective case around the brain. In the human skull, the neurocranium includes the calvaria or skullcap. The remainder of the skull is the facial skeleton.

What does neurocranium consist of?

The neurocranium forms the cranial cavity that surrounds and protects the brain and brainstem. The neurocranium consists of the occipital bone, two temporal bones, two parietal bones, the sphenoid, ethmoid, and frontal bones—all are joined together with sutures.

What is the difference between neurocranium and viscerocranium?

The neurocranium is a protective shell surrounding the brain and brain stem. The viscerocranium (or facial skeleton) is formed by the bones supporting the face.

Where is the dermatocranium?

skull
The dermatocranium is the portion of the cranium that is composed of dermal bone, as opposed to the endocranium and splanchnocranium, which are composed of endochondral bone. The dermatocranium comprises the skull roof, the facial skeleton (usually excluding the dentary), and—in fishes—the opercular bones.
