The Autonomic Nervous SystemRegulate activity of smooth muscle, cardiac muscle & certain glandsStructures involvedgeneral visceral afferent neuronsgeneral visceral efferent neuronsintegration center within the brainReceives input from limbic system and other regions of the cerebrumGoverned by the hypothalamus that is located in the diencephalonsĪutonomic versus Somatic NSAutonomic NS pathway is a 2 neuron pathway Somatic NS pathway only contains one neuron.īasic Anatomy of ANSPreganglionic neuroncell body in brain or spinal cord axon is myelinated type B fiber that extends to autonomic ganglion

Organization of the Nervous SystemPeripheral Nervous SystemNerves and ganglia outside the central nervous systemNerve = bundle of neuron fibersNeuron fibers are bundled by connective tissue ectodermal thickens to form the neural plate- closes neural tubeneural crest Dorsal root ganglia (autonomic nervous system)Migrate to form through the embryo: parasympathetic / sympathetic ganglia.Embryologically, adrenal medulla is derived from same cells as postganglionic ANS cells. This becomes the notochord, which marks the head/tail axis of the embryo.
