Answer:
The junction between two communicating neurons is called a synapse; there is a gap between them across which the impulse must be conveyed. Synaptic transmission it the process by which the impulse in the presynaptic neuron is transmitted across the synaptic cleft to the postsynaptic neuron. When an impulse reaches the synaptic knob of an axon, synaptic vesicles release chemicals called neurotransmitters into the synaptic cleft. These chemicals react with specific receptors on the postsynaptic membrane.
Explanation:
These are the key steps involved in synaptic transmission, which usually takes place at the neuromuscular junction.
Synapses may be chemical or electrical. In this case, it is a chemical synapse because it involves the transmission of information via chemical mediators.
The release of neurotransmitter molecules into the synaptic cleft is triggered by the influx of calcium ions via voltage-gated ion channels.
Answer:
Explanation:
In the nervous system, a synapse is a structure that permits a
neuron (or nerve cell) to pass an electrical or chemical signal to
another neuron or to the target effector cell.
Neurotransmitter, also called chemical
transmitter or chemical messenger, any of a
group of chemical agents released by neurons
(nerve cells) to stimulate neighbouring neurons
or muscle or gland cells, thus allowing impulses
to be passed from one cell to the next throughout the nervous
system.
the synaptic cleft is the physical space between these two
neurons. the space that separates a neuron and its target cell at a
chemical synapse.
