Question

What is synapse? In a neurone cell how is an electrical impulse created and what is the role of snapse in this context?​

Answer 1

Answer:

• a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter

Synapse is the junction between two adjustment neuron or nerve cells, i.e. between axon ending of one and the dendrite of the next. Transmission of Nerve Impulse. The information acquired at the end of the dendritic tip of a neuron sets off a chemical reaction which creates an electrical impulse. This impulse travels from the dendrite to the cyton along the axon to its end. At the end of the axon, the electrical impulse sets off the release of some chemicals, which cross the synapse and start a similar electrical impulse in a dendrite of the next neuron. In this way nerve impulses travel in the body.

Answer 2

synapse

The term synapse means “coming together.” Where two structures or entities come together, they form a synapse. Although one can use the word synapse to mean any cellular junction, in physiology we traditionally limit its usage to the junction of two neurons and the junction between a neuron and a target cell or the interface between adjacent cardiac muscle cells or adjacent smooth muscle cells. In the nervous system, a synapse is the structure that allows a neuron to pass an electrical or chemical signal to another cell.

Synapseis the functional junction between two neurons. The information acquired at the dendride tip create electrical impulses which are passed to cell body and then transmitted to end of nueron through axon. At the end of neuron the impulses set off certain chemicals which cross the synapse and create similar impulse in the dendride tip of the next neuron.
