Video: Sympathetic Nervous System: Definition, Function & Effects. The autonomic nervous system is the portion that controls all of the involuntary functions of the body. This includes the body's response to emergency situations. In this article, we discuss the sympathetic nervous system and its responses under these circumstances.
The autonomic nervous system helps to regulate the activities of cardiac muscle, smooth muscle, and glands ,. In this regulation, impulses are conducted from the CNS by an axon that synapses with a second autonomic neuron. It is the axon of this second neuron in the pathways that innervates the involuntary effectors.Autonomic motor nerves innervate organs whose functions are not usually under voluntary control. The effectors that respond to autonomic regulation include cardiac muscle (the heart) , smooth (visceral) muscles, and glands.regangliotic neurons of the sympathetic division of the autonomic system originate in the thoracic and lumbar (thoracolumbar) levels of the spinal cord and send axons to sympathetic ganglia, which parallel the spinal cord.
