Question

The functional junction between two neurons is

• A. neurotransmitter
• B. CSF
• C. Neuroplasm
• D. synapse

Answer 1

The correct option is D

synapse

The correct answer is D.

Explanation for correct option-

1. A synapse acts as the functional junction between the two neurons and allows the impulse from one neuron to travel into another.
2. A synapse or a neuronal junction is a narrow gap that consists of the communicating junction present between the two neurons.

Explanation for incorrect option-

Option A:

1. Neurotransmitters are the body's chemical messengers secreted by the neurons.
2. Neurotransmitters are used by the nervous system which transmit messages between the neurons or from the neuron to muscles.
3. Neurotransmitters transmit messages, they do not act as the functional function between two neurons.

Option B:

1. Cerebrospinal fluid (CSF) acts as a protective layer in the brain and the spinal cord.
2. CSF is produced by the choroid plexus.

Option C:

1. Neoplasm is the cytoplasm of the nerve cell.
2. It serves as a fluid medium over which the organelles are present.

Final Answer: The functional junction between two neurons is Synapse.
