What is the function of this neurone?

• Carry impulse from the sensory neurone to the motor neurone across the spinal cord.

• Carry impulse from the sensory organ to the brain.

• Carry impulse from the relay neurone going out to the effectors.

• Carry impulse from the effectors to the central nervous system.

Which of the following is the component of human central nervous system?

• Controls all activities of the neurone

What is the function of this neurone?

• Transmit impulses from sensory neurone to motor neurone

• Carries impulse from central nervous system to effector

• Carry impulse from the effectors to the central nervous system

• Carries impulse from sensory organ to central nervous system
