For protection and to stop your brain flopping about and annoying people.
The bony structure that surrounds the brain is called the skull or cranium. It provides protection and support for the brain, as well as anchoring muscles and providing structure for the face.
The membranes between the central nervous system (CNS) and its bony covering are known as meninges. There are three layers of meninges: the dura mater, arachnoid mater, and pia mater. They serve to protect and cushion the brain and spinal cord.
The braincase holds and protects the brain. It is a bony structure that encloses and supports the brain within the skull, providing vital protection from external trauma.
The structure you are referring to is called the skull. It is a bony or cartilaginous structure that surrounds and protects the brain of chordates, including vertebrates. The skull plays a critical role in providing support and protection for the brain and sensory organs.
The flap of tissue that covers a bony fish gill is the bony operculum.
scales
Denticles are small tooth-like structures found on the skin of cartilaginous fish like sharks and rays. They differ from the bony fish's scales, which are hard, flat plates covering their bodies. Denticles help reduce drag in water and provide protection, while scales are more rigid and serve as a form of armor for bony fish.
The outer covering of the brain is called the meninges. It is made up of three layers: the dura mater, arachnoid mater, and pia mater. These layers provide protection and support for the brain and spinal cord.
The bony covering that protects the brain is called the skull. It is made up of several bones, including the frontal, parietal, temporal, and occipital bones, which together form a sturdy and protective barrier around the brain.
You might be a fish from the Placoderm group. Placoderms were an extinct fish group known for their armor-like bony plates covering their bodies, providing protection. They existed during the Paleozoic era, from around 430 to 360 million years ago.
The central nervous system (CNS) is surrounded by bone for protection. It also has additional protection from a covering called the meninges. The cranial cavity protects the brain.And the vertebral cavities protect the spinal cord. Together, they are referred to as the dorsal cavity.
