What is the function of the nervous system? - Answer Monitoring of changes inside and outside of the body The brain and spinal cord are included in which division of the nervous system? (abbreviation) - Answer CNS The cranial nerves, spinal nerves, and ganglia are included in which division of the nervous system? (abbreviation) - Answer PNS Sensory information travels to the brain in the afferent or efferent nervous system? - Answer Afferent Motor information/commands travel to the s...

how is the autonomic PNS different from the somatic PNS? - autonomic PNS is a two neuron pathway from spinal cord to effector whereas the somatic PNS is a one neuron path - motor axons of the autonomic PNS have cell bodies outside of the CNS whereas somatic LMN have cell bodies within the CNS - autonomic PNS is responsible for innervating visceral tissues whereas somatic PNS is responsible for innervating body wall tissue (motor division) - somatic sensation = of body wall and is well locali...

Three fundamental physiological properties of neurons, or nerve cells - Answer-Excitability Conductivity Secretion Excitability - Answer-the ability of a cell to respond to a stimulus, especially the ability of nerve and muscle cells to produce membrane voltage changes in response to stimuli; also called irritability -all cells are excitable -nerve cells are excitable to the highest degree Conductivity - Answer-Neurons respond to stimuli by producing electrical signals that are quickly c...

Collection of cell bodies in the PNS Ganglia This part of the autonomic NS increases digestion parasympathetic NS Ventral root of a nerve contains what type of neurons? motor Neuron part that conducts nerve impulse away from body axon An interneuron inside the spinal cord is part of the central nervous system Describe Synthesis & Storage of Neurotransmitters Cell body manufactures NT's, they are stored in the secretory vesicles at the end of the axon terminal ...

neuron correct answers basic unit of the nervous system; can vary in size from 4-100 microns; provide the means for recieving and sending information through the entire nervous system cell body correct answers contains the nucleus; regulates the homeostasis of the neuron dendrites correct answers extensions from the cell body; primarily responsible for receiving information from other neurons. Prevalence per neuron varies. (0-1000s) axon correct answers aka nerve fiber; responsible for ...
