Web“ Nerve impulse conduction ” refers to the propagation of nerve impulse that occurs due to a change in membrane potential beyond the cell membrane. When a nerve impulse or action potential reaches the axon terminal, synaptic transmission occurs via an electrical or chemical synapse. WebA synapse between neurons is best described as the a.Transmission of a continuous impulse b.Transmission of an electrical impulse c.Transmission of an impulse through a chemical and physical change d.Transmission of an impulse through a physical change e.Transmission of an impulse through a chemical change 19.–23.

WebMar 14, 2024 · neurotransmitter release, discharge of chemical substances known as neurotransmitters from a neuron in response to a given stimulus. Neurotransmitter release occurs at synapses, which are the sites of transmission of electric nerve impulses between two neurons or between a neuron and a gland or muscle cell. WebJun 8, 2024 · Neurotransmission at a chemical synapse begins with the arrival of an action potential at the presynaptic axon terminal. When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated Na + channels. Na + ions enter the cell, further depolarizing the presynaptic membrane.
