Final Answer:
The second top plate is also known as the epicranium.
Step-by-step explanation:
In anatomical terms, the human skull is divided into several plates, and the second top plate is referred to as the epicranium. This term is derived from the combination of epi, meaning upon or above, and cranium, which pertains to the skull. The epicranium plays a crucial role in protecting the brain and supporting various sensory organs housed within the skull.
The epicranium consists of the frontal bone, which forms the forehead and the upper part of the eye sockets. It extends to the parietal bones that shape the sides and top of the skull. The sagittal suture, a fibrous joint between the parietal bones, is a prominent feature of the epicranium. Additionally, the coronal suture, where the frontal bone meets the parietal bones, contributes to the overall structural integrity of the skull. Understanding these anatomical terms aids in precise communication within the medical and scientific communities, ensuring clarity when discussing specific regions of the human skull.
In summary, the term epicranium accurately denotes the second top plate of the skull, encompassing the frontal and parietal bones. This anatomical nomenclature is crucial in medical and academic contexts, providing a standardized way to describe the complex structures of the human skull.
