WebSep 4, 2024 · The place where an axon terminal meets another cell is called a synapse. This is where the transmission of a nerve impulse to another cell occurs. The cell that sends the nerve impulse is called the presynaptic cell, and the cell that receives the nerve impulse is called the postsynaptic cell. WebFeb 14, 2024 · A synapse is a combination of the following: Presynaptic endings – which contain the neurotransmitters (chemical messengers). Synaptic clefts – which is the gap between the two neurons. Postsynaptic endings – which contain the sites for receptors (molecules that receive signals for a cell).

WebSynaptic transmission is the process at synapses by which a chemical signal (a transmitter) is released from one neuron and diffuses to other neurons or target cells where it generates a signal which excites, inhibits or modulates cellular activity. WebThere is a small gap between the two neurones called a synapse. In order for an impulse to be generated in the next neurone, a chemical transmitter is released. This then diffuses across the small gap. Many drugs work by interfering with synapses. They may block or copy the action of neurotransmitters in certain neurones. Username * Password *
