Answer:
The Central Nervous system is made up of the brain,the control units,and the spinal cord ,the network of nerves ,which feed the brain with sensory information for processing.The entire CNS is lined by a constantly circulating fluid called the Cerebrospinal Fluid.(CSF).
Together with the Peripheral Nervous system,the CNS ensure coordination of the body activities.
Generally both the brain and the spinal cord are protected by the skull and vertebral column respectively. Their activities are based on the million of neurons which are networked by synapses.
Functions are:
processing information that is received from the stimuli receptors
sending out information so that the body can react appropriately to stimuli
coordinating reflexes and reactions to stimuli.
These functions are performed through the fast reflex pathways, for efficient coordination of the systems of the body by the CNS with PNS
