Question

What occurs at synapses between two neurons?
(A)Synaptic transmission of stimulus
(B)The signals will be diminished
(C)Jumping of the stimulus from one synapse to another
(D)Generation of electric signals

Answer 1

Hint: A synapse is a gap between the two neurons. In a synapse, the electrical signals are transformed into chemicals so they can cross over the gap and pass on to the next neurons where it is furthermore converted into electrical signals.

Complete answer:Neurotransmission is the procedure by which signaling molecules named neurotransmitters are discharged by the axon terminal of a neuron known as the presynaptic neuron, and attach to and respond with the receptors on the dendrites of another neuron. Neurotransmission is governed by several different factors: The availableness and rate-of-synthesis of the neurotransmitter, the discharge of that neurotransmitter, the baseline activity of the postsynaptic cell, the number of available postsynaptic receptors for the neurotransmitter to attach to, and deactivation of the neurotransmitter by enzymes.
Stages of neurotransmission:
-Synthesis of the neurotransmitter. This can take place in the cell body, in the axon, or the axon terminal.
-Storage of the neurotransmitter in storage granules in the axon terminal.
-Calcium reaches the axon terminal during an action potential, resulting in the release of the neurotransmitter into the synaptic cleft.
-After its discharge, the transmitter attaches to and initiates a receptor in the postsynaptic membrane.
-Deactivation of the neurotransmitter. The neurotransmitter is either eliminated enzymatically, or it can be reused or degraded and excreted out
-Communication of nerve impulses between two neurons takes place through the synapse. The axon terminal of a neuron discharges specialized chemicals called neurotransmitters. These chemicals move through the synapse and reach the dendrites of the next neuron. The nerve impulses move along with the neurotransmitters.
Thus the correct answer is option A

Note: A synapse is a way that allows a neuron to depart an electrical or chemical signal to another neuron or we can say targeted cells. Synapses are important to neuronal function: neurons are cells that are specialized to pass signals to particular target cells.
