Which of the following best describes the anatomical structure of the skull?

The anatomical structure of the skull is best described as being composed of multiple segments. The human skull is made up of two primary parts: the cranium and the facial bones. The cranium itself is divided into several individual bones, such as the frontal, parietal, occipital, temporal, sphenoid, and ethmoid bones. Each of these bones is connected by sutures, which are fibrous joints that allow for some flexibility during development, especially in infants.

This segmented structure is essential for protecting the brain and supporting the structures of the face. Understanding that the skull is not a single hollow entity, flexible cartilage, or entirely constructed from fibrous tissue helps clarify its complex anatomy. Instead, it is a composite structure that plays vital roles in protection and support, allowing for a range of functions including housing sensory organs and forming the framework for mouth and jaw movements.
