The epidermis is usually a thick keratinized epithelium manufactured from many mobile layers. Beneath the epidermis is definitely the dermis, a layer of connective tissue that contains blood vessels and nerves that provide the skin.

Additionally it is stuffed with CSF and it communicates Together with the ventricles with the Mind. The CNS is made from neurons and their procedures (axons). Grey matter is made of neuron cell bodies, it can be located in the cerebral cortexand the central portion of the spinal cord.
