The correct answer is -
The CNS involves the brain and spinal cord, and the PNS involves the body nerves.
CNS (central nervous system) and PNS (peripheral nervous system) are the two different branches of nervous system in the human body.
CNS is further divided into Brain and spinal cord and it is responsible for receiving and interpretation of different information coming from the body parts. It controls most of the functions of body.
PNS on the other hand, possesses nerves that leave brain and spinal cord and innervates the rest of the body parts. In other words, it connects the CNS to other body organs.
Thus, first option is the right answer.
Central nervous system:
Central nervous system consists of the brain and the spinal cord. Short nerve impulse are present in the central nervous system. The information are obtained from the sensory organs. The damage of nerve fibers are irreparable in the central nervous system.
Peripheral nervous system:
Peripheral nervous system consists of the motor neurons, sensory receptor and sensory neurons. Long nerve impulse are present in the peripheral nervous system. The information are pass out to the effector organs. The damage of nerve fibers are reparable in the peripheral nervous system.
CNS includes the brain and spinal cord which analyze sensory inputs, whereas PNS consists of neurons and nervous tissues that carry the information.
The nervous system has two distinct main parts - the peripheral nervous system (PNS) and the central nervous system (CNS).
CNS contains the spinal cord and the brain serves the nervous system's command center. the spinal cord and the brain analyze sensory inputs what it exactly means and quickly orders the body parts that time to move faster.
PNS consists of the nerves, which leave the brain and the spinal cord and travel to evident regions of the body. The main job of PNS is to send information collected by the sensory receptors to the CNS.
The answer is A
The CNS consists of the brain and spinal cord, while the PNS includes all other nervous system tissue. Hope this helps!
