what is synapse ? which event occurs in it?
Answers
Answer:
Explanation:
Synapse
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 cell (neural or otherwise).
Synapses are essential to neuronal function: neurons are cells that are specialized to pass signals to individual target cells, and synapses are the means by which they do so. At a synapse, the plasma membrane of the signal-passing neuron (the presynaptic neuron) comes into close apposition with the membrane of the target (postsynaptic) cell.
Occurence
In many synapses, the presynaptic part is located on an axon and the postsynaptic part is located on a dendrite or soma. Astrocytes also exchange information with the synaptic neurons, responding to synaptic activity and, in turn, regulating neurotransmission.
Answer:
Synapse is the gap between the axonal end of one neuron and the dendrite of another neuron.
Explanation:
The electrical impulse travelling through the axon at the axonal end generate chemicals which travel through the gap to the next neuron. This process is necessary for the nervous system to receive and send messages(electric impulses) to different parts of the body.
