The two divisions of the autonomic nervous system: Compare and contrast form and functionExamples to clarify and teach. Parasympathetic nervous system: The sympathetic system is associated with the fight-or-flight response, and parasympathetic activity is referred to by the epithet of rest and digest. The medulla, pons, and midbrain are collectively called the … Anatomically and functionally, the autonomic nervous system is made up of two subdivisions: the sympathetic system with long-lasting and diffuse effects, and the parasympathetic system with more transient and specific effects. The peripheral nervous system is made up of thick bundles of axons, called nerves, carrying messages back and forth between the CNS and the muscles, organs, and senses in the periphery of the body (i.e., everything outside the CNS). The autonomic system is subdivided into the sympathetic and parasympathetic systems. There are three subdivisions of the autonomic nervous system - the parasympathetic nervous system (rest and digest), the sympathetic nervous system (fight or flight) and the enteric system (lines the gastrointestinal tract). One of its major side effects is constipation. We tend to think of the parasympathetic and sympathetic systems as competing each other. The PNS has two major subdivisions: the somatic nervous system and the autonomic nervous system. The first nerve cell is called a preganglionic neuron, and its cell body is located within the CNS.The ANS carries nerve impulses from the CNS to the effector organs by way of two types of efferent neurons.One of its major side effects is tachycardia (an increase in heart rate). These two subdivisions of the autonomic nervous system work in opposition to one another.
The heart rate is controlled independently by a pacemaker called the sinoatrial node (SAN). The somatic motor system controls voluntary movement of muscles.
