Detailed explanation-1: -The dorsal body cavity contains the central nervous system. It consists of two parts: The Cranial Cavity (Cranium) is formed from skull bones and houses and protects the brain. The Spinal Cavity (Spinal Canal) is formed from the vertebrae of the spine, and houses and protects the spinal cord.
Detailed explanation-2: -Three layers of membranes known as meninges protect the brain and spinal cord. The delicate inner layer is the pia mater. The middle layer is the arachnoid, a web-like structure filled with fluid that cushions the brain.
Detailed explanation-3: -An inner layer (meningeal), lines the inside of the entire skull and creates little folds or compartments in which parts of the brain are protected and secured.
