10/21/14 Nervous system: one of the eleven major body organ systems in animals; coordinates and controls actions of internal organs and body systems; receives and processes sensory information from external environment; coordinated short-term reactions to these stimuli. Cell body: the part that contains the nucleus and most of the cytoplasm and the organelles. Axon: sends messages away from the cell body to other neurons. Dendrite: short‚ highly branched fibers that carry signals toward the cell

These neurotransmitters transfer signals throughout the nervous system and stimulates action potentials in the postganglionic neurons. Receptors found on the ANS and PNS includes the cholinergic receptors‚ which consists of all sympathetic and parasympathetic preganglionic‚ sympathetic postganglionic and all parasympathetic postganglionic neurons. The cholinergic receptors are found in the postsynaptic plasma membrane
