nerves that carry impulses toward the cns only are ______.

Explanation:

To solve this, we analyze each option:

• Mixed nerves carry both sensory and motor impulses, so not just toward CNS.
• Afferent (sensory) nerves transmit impulses from receptors to the Central Nervous System (CNS), matching the description.
• Motor (efferent) nerves carry impulses from CNS to effectors, opposite direction.
• Efferent nerves are same as motor nerves, carry away from CNS.
