A1 - Kruidering-Hall, Marieke PY - 2020 T2 - Pharmacology for the Physical Therapist, 2e AB - The autonomic nervous system (ANS) provides bidirectional communication (afferent and efferent fibers) between the brain and smooth muscle, cardiac muscle, and exocrine and endocrine glands. Its name is derived from the fact that the activities of the ANS are largely independent (ie, autonomous) of direct conscious control. The ANS is concerned primarily with necessary visceral functions like modification of blood flow to organs, digestion, and regulation of cardiac output. Afferent (sensory) fibers provide information regarding the internal and external environment and modify motor output through reflex arcs of varying size and complexity.
