Question

Answer

Synapse is minute gap between two neurons .where chemical substance called neurotransmitters is passed . It acts as a one way valve

Answer

Synapse is the gap between two neurons, ended by synoptic knobs...

Answer

Synapse is the gap between the nerve ending of one neurone and dendrites of another at synapse the electrical impulse generated from the dendrites of one neurone Travels the dendrites of another in the form of chemicals byauxin ending of the first neurone synapse insured at nerve impulse travel only in One Direction a similar synapse allow the delivery of neuronsfrom neurone to the others like muscle cells.and  hence the correct option is D

Answer

Synapse.

Answer

Interneuron Junction: Synapse

The correct answer is option 'D', synapse. The synapse is the junction between two neurons where neurotransmitters are released. Let's understand this in detail:

Neurons and their Parts
Neurons are specialized cells of the nervous system that transmit signals in the form of electrical impulses. They consist of three main parts:

1. Cell Body: The cell body, also known as the soma, contains the nucleus and other organelles necessary for the neuron's functioning.
2. Axon: The axon is a long, slender fiber that carries electrical signals away from the cell body to other neurons or target cells.
3. Dendrites: Dendrites are shorter, branched extensions that receive signals from other neurons and transmit them towards the cell body.

Interneurons
Interneurons, also known as association neurons or internuncial neurons, are responsible for relaying information between sensory and motor neurons. They facilitate communication within the central nervous system (CNS) and play a crucial role in integrating and coordinating signals.

Synapse
The synapse is the junction where two neurons come into close proximity to transmit signals. It consists of three main parts:

1. Presynaptic Neuron: This is the neuron that sends the signal. The axon terminal of the presynaptic neuron contains vesicles filled with neurotransmitters.
2. Synaptic Cleft: The synaptic cleft is a tiny gap between the presynaptic and postsynaptic neurons.
3. Postsynaptic Neuron: This is the neuron that receives the signal. The dendrites or cell body of the postsynaptic neuron contain receptors for neurotransmitters.

Neurotransmitter Release
When an electrical impulse reaches the axon terminal of the presynaptic neuron, it triggers the release of neurotransmitters from the vesicles into the synaptic cleft. The neurotransmitters diffuse across the synaptic cleft and bind to specific receptors on the dendrites or cell body of the postsynaptic neuron.

Effect on Postsynaptic Neuron
The binding of neurotransmitters to receptors on the postsynaptic neuron can either excite or inhibit its activity, depending on the type of neurotransmitter and receptor involved. If the neurotransmitter is excitatory, it will increase the likelihood of the postsynaptic neuron firing an action potential. Conversely, if the neurotransmitter is inhibitory, it will decrease the likelihood of an action potential.

In conclusion, the correct answer is option 'D', synapse, where neurotransmitters are released from the axon terminal of the presynaptic neuron and bind to receptors on the dendrites or cell body of the postsynaptic neuron.
