Detailed explanation-1: -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-2: -Sensory neurons are nerve cells responsible for converting external stimuli from an individual’s environment into internal electrical impulses. They are the type of neurons that send nerve impulses to CNS from receptor organs.
Detailed explanation-3: -Overall, motor neurons (or motoneurons) comprise various tightly controlled, complex circuits throughout the body that allows for both voluntary and involuntary movements through the innervation of effector muscles and glands. The upper and lower motor neurons form a two-neuron circuit.
