Identify the incorrect statement(s) regarding the components of PNS.
I. The nerves carrying impulses from CNS to peripheral system are sensory nerves or afferent nerves.
II. The nerves carrying impulses from peripheral system to CNS are motor nerves or efferent nerves.
III. Afferent nerves bring in impulses from the auditory, visual and touch receptors.
IV. Efferent nerves coordinates impulses towards effector organs.

IV. Efferent nerves coordinates impulses towards effector organs.
The correct option is A I and II
In reference to the statements; I and II are incorrect because :
1. Afferent nerve fibres carry impulses from the receptors to the CNS. They are also called sensory nerves because they bring in sensory information to the CNS.
2. Efferent nerve fibres conduct nerve impulses from the CNS to the effector organs such as muscles and glands. They are also called motor nerves because they carry information from the CNS for motor response.
