II. The nerves carrying impulses from peripheral system to CNS are Motor nerves or Afferent nerves

IV. Motor system coordinates impulses towards effector organs.

• A. I and II
• B. III and IV
• C. I and III
• D. II and IV

Answer 1

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.
