BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The motor neurons carry impulses from the CNS to the effectors.

Detailed explanation-2: -Efferent, or motor, neurons transmit impulses from the CNS to effector organs such as muscles and glands. Efferent neurons usually have short dendrites and long axons.

Detailed explanation-3: -Neurons are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external environment. A neuron that transmits the impulse from the sensory neuron to a motor neuron is a relay neuron.
