What is the role of sensory nerves (afferent nerves)?

  1. Carry impulses from the brain to muscles or glands

  2. Carry impulses or messages from the sense organs to the brain

  3. Control voluntary muscular activity

  4. Regulate heart and breathing rate

The correct answer is: Carry impulses from the brain to muscles or glands

Sensory nerves, also known as afferent nerves, are responsible for carrying impulses or messages from the sense organs to the brain. These nerves play a crucial role in transmitting sensory information such as touch, temperature, pain, and pressure from the skin and other sensory organs to the brain for processing. This information helps the brain interpret and respond to external stimuli. The option "Carry impulses or messages from the sense organs to the brain" accurately describes the role of sensory nerves.
