Synapses and ReflexesSynapses connect Neurons.The connection between 2 neurons is called a synapse,the nerve signal is transferred by chemicals whichdiffuse cariss the gap, these chemicals then set off anew electrical signal in the next neurone.Reflexes helpprevent injury.Reflexes are rapid and automatic to certain stuffthat don't involve the consious part of the brain-they can reduce that chances of injury, the assge ofinofrmation ina reflex is called a felfex arc.The reflex arc goesthrough the CentralNervous System(CNS).The neurons in reflex arcs got through the spinal cord or throughan unconsious part of the brain, when a stimulus is detected byreceptors impulses are sent along a sensory neurone to a relayneurone in the CNS, when the impulses reach a synapse betweenthe sensory neurone and the relay neurone they trigger chemicalto be released which causes impulses to be sent along the relayneurone, when impulses reach a synapse between the relay andmotor neurone impluses are sent which travel along the motorneurone to the effector which is usually a muscle.hsbdjnClique duas vezes aqui para editar o textoClique e arraste este botão para criar um novo tópico
