stimulates effector cells

Detailed explanation-1: -Answer and Explanation: In contrast to the somatic nervous system, the autonomic nervous system uses a two efferent neuron chain. The autonomic nervous system has efferent neurons-namely the preganglionic and the postganglionic neurons.
Detailed explanation-2: -The somatic nervous system has sensory and motor pathways, whereas the autonomic nervous system only has motor pathways. The autonomic nervous system controls internal organs and glands, while the somatic nervous system controls muscles and movement.
Detailed explanation-3: -The further classification used of the efferent division is the somatic and autonomic nervous system (ANS). Simply put, the somatic nervous system innervates skeletal muscle, whereas the ANS innervates glands, neurons of the gastrointestinal tract, and cardiac and smooth muscles of glandular tissue.
Detailed explanation-4: -Efferent Pathways of the Autonomic Nervous System The efferent pathways of the ANS consist of 2 neurons that transmit impulses from the CNS to the effector tissue.
