Assistant Professor Dr Hayder B Sahib PhD Pharmacology INTRODUCTION TO ANS The nervous system is divided into the central nervous system CNS and peripheral nervous system The peripheral nervous system is divided into somatic voluntary and the autonomic system .

The autonomic nervous system-is part of the peripheral nervous system that supplies motor activity to the visceral effector organs, glands, smooth muscles within the organs and the heart..

Def: The ANS consists of all visceral motor neurons innervating smooth muscle, cardiac muscle and glands.. Divide Autonomic Pharmacology into Four Categories:. 1. Drugs that increase the sympathetic nervous system response . Spinal Cord Anatomy. Extends from the foramen magnum of the skull to the first or second lumbar vertebra. Provides a two-way conduction pathway from the brain to and from the brain. 31 pairs of spinal nerves arise from the spinal cord. Dr . IramTassaduq. 3.
