Document Summary

All nervous tissue outside cns, excluding the ens. Neural tissues in wall of gi tract; helps control digestive function. Information processing - integrates, processes, coordinates sensory and motor commands. Take information from the receptors (whether in the skin or within the organs: motor/efferent division - carries motor commands from the cns out to the effector organs; efferent = exiting the cns. Sns - somatic; voluntary; soma means body, so sns goes to the body wall and our extremities; things we consciously control, like skeletal muscle. Dendrites - connected to cell body; here is where the neuron receives information; highly branched to receive stimuli from environment or other neurons. Cell body - contains nucleus and other organelles. Perikaryon - cytoplasm; contains organelles that provide energy/synthesize neurotransmitters. Cell body lies in cns; axon extends within a peripheral nerve (nerve=a bundle of axons in the. Somatic motor - voluntary and reflexive motor to skeletal muscle. Visceral sensory - detecting visceral stimuli from interoceptors.
