Question

What is the relationship between the central and peripheral nervous systems and the sensory organs?

Please type answer, im awful at reading others handwriting.

Answer 1

    The central nervous system or the CNS contains the brain and the spinal cord. Everything else the CNS it is known as the peripheral nervous system. The peripheral nervous system (PNS) refers to all the neurons (and their supporting cells, or glia) of the body outside the brain and spinal cord. Peripheral nervous system and its information gathering capabilities to receive information about the world and to send appropriate responses the CNS as quickly as possible. Once the CNS has understood the information, the PNS will relay the specific orders back out the body. These nerves which carry information in a way of nerve impulses to and from the brain are called cranial nerves. The nerves that carry impulse to and are carrying information from the spine are called spinal nerves. Peripheral neurons are of two types, sensory and motor. Sensory (afferent) neurons bring information about the world within and around the body from sense organs to the brain and spinal cord, while motor (efferent) neurons carry messages from the brain and spinal cord out to the muscles and glands. the sensory division collects the impulses from the sensory receptors in areas like skin, muscles, and organs, and also carries those impulses through the nerves to the CNS. The motor division collects the outgoing messages from the CNS and delivers them to the appropriate body organs, telling them what to do. Thus how CNS and pheripheral nervous system help in relay of signal form sense organs to brain and back to sense organs.
