"Brain bone" isn't a specifically defined anatomical term, but it most likely refers to the bones that make up the cranium, which encloses and protects the brain.
The Cranium: Protector of the Brain
The cranium, also known as the neurocranium, forms the superior part of the skull. Its primary function is to safeguard the brain, its surrounding meninges (protective membranes), and the cerebral vasculature (blood vessels). The cranium is comprised of several bones joined together.
Bones of the Cranium
According to the provided reference, the cranium can be divided into the cranial roof and base:
- Cranial Roof: This is formed by the following bones:
- Frontal bone
- Occipital bone
- Two Parietal bones
- Cranial Base: (Not detailed in the provided reference, but essential to the whole structure, made up of multiple bones).
Therefore, in simpler terms, "brain bone" can be understood as the collection of bones, such as the frontal, occipital, and parietal bones, that form the cranium and shield the brain.
