What do moto nerves do?

  1. Carry impulses from muscles to the brain

  2. Carry impulses from the brain to the muscles

  3. Transmit sensory information

  4. Regulate blood flow

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

Moto nerves, also known as motor nerves, are responsible for transmitting impulses from the brain to the muscles. This allows for voluntary movement and control over muscle contraction. Option A is incorrect because sensory nerves, not moto nerves, carry impulses from muscles to the brain. Option C is incorrect because sensory nerves are responsible for transmitting sensory information, not moto nerves. Option D is incorrect because motor nerves do not play a role in regulating blood flow, which is controlled by the cardiovascular system.
