There are two types of thermistors: Negative Temperature Coefficient (NTC) and Positive Temperature Coefficient (PTC). With an NTC thermistor, when the temperature increases, resistance decreases. Conversely, when temperature decreases, resistance increases.This type of thermistor is used the most.here are two types of thermistors: Negative Temperature Coefficient (NTC) and Positive Temperature Coefficient (PTC).

Problem 22E: Four of the twelve cranial nerves carry parasympathetic moto... Four of the twelve cranial nerves carry parasympathetic motor output. In the table below, list the nerves that carry parasympathetic motor output, and then give the parasympathetic function(s) of each nerve. Chapter , Problem is solved.
1 The sympathetic division of the autonomic system activates the body to fight or flight through adrenergic effects. 2  The parasympathetic division often exerts antagonistic actions through cholinergic effects. 3  All preganglionic autonomic nerve fibers are cholinergic (use ACh as a neurotransmitter). Preganglionic parasympathetic fibers originate in the brain and in the spinal cord. 2  Preganglionic parasympathetic fibers contribute to cranial nerves III, VII, IX, and X. 3  The long preganglionic fibers of the vagus (X) nerve synapse in terminal ganglia located next to or within the innervated organ.
