WebFeb 9, 2024 · This is done using chemicals which diffuse across the gap between the two neurons. These chemicals are called neurotransmitters. Neurotransmitters are chemical messengers that are released from a synaptic vesicle into the synapse by neurons. Some neurotransmitters act by making the neuron more negatively charged so less likely to fire. WebE) Most synapses in the nervous system are chemical synapses. B Which of the following statements about electrical synapses is FALSE? A) Gap junctions are formed from proteins called connexins. B) Electrical synapses connect hypothalamic neurons that release tropic hormones. C) Electrical synapses are found in the retina. WebChemical synapses involve the release of neurotransmittters by the presynaptic nerve terminal of one neuron, which then influences the function of a second neuron.
