How Are Impulses Transmitted In The Nervous System?
Web30 mrt. 2016 · Neurotransmitters (small molecules) Explanation: When the impulse (or 'action potential') reaches the presynaptic terminal (the end of the neuron), it causes a number of vesicles containing neurotransmitters to be released into the synaptic cleft (the bit between the two neurons). WebThey are usually electrical signals that travel along the axon of the neuron. Neurons communicate with each other at specific points or junctions called synapses. These … swadeshi yoga clothing
