Which substance is responsible for the transmission of nerve impulses at synapses?

Last Updated: 26 Jun 2026

This concept is important for examinations because SSC often converts a textbook statement into a direct MCQ or uses closely related terms as distractors. Restate the question in your own words, predict the answer before checking the options, and confirm that the explanation and correct-option field both point to Neurotransmitter.

AHaemoglobin

BInsulin

CNeurotransmitter

DEnzyme

Correct Answer: NeurotransmitterYour Answer: C

Explanation

Do not confuse an organ that produces a substance with an organ on which that substance acts, or a vector with the organism that causes a disease. Therefore option C, Neurotransmitter, is factually consistent with the stem, the marked correct index, and the explanation.✅ Correct Answer: C — Neurotransmitter They bind to receptors on the next neuron and transmit the nerve impulse forward. Haemoglobin — It is a protein in RBCs that carries oxygen, not involved in nerve signal transmission. Insulin — A hormone secreted by the pancreas to regulate blood glucose levels; has no role at synapses. Enzyme — Enzymes catalyze biochemical reactions but do not transmit nerve impulses between neurons. Neurotransmitters are the only molecules responsible for chemical transmission across synapses.

Important Notes

this record is Neurotransmitter, corresponding to option C. The answer field, correct index, and both explanations must remain aligned.
Read the complete stem and identify the exact demand: organ, gland, hormone, cell, tissue, nutrient, enzyme, pathogen, vector, deficiency disease, body fluid, or physiological function.
Revise every structure with its location and principal function. For example, separate production from storage, transport from exchange, filtration from detoxification, and control from execution.
Haemoglobin, Insulin, Enzyme are eliminated here because none satisfies the precise requirement of the stem. Practising the reason for each rejection is more reliable than memorising only the correct choice.

FAQ

SSC CGL Human Body FAQs

Common questions and clear answers for this topic.

Which body systems are most important for SSC CGL preparation?

The digestive, circulatory, nervous, and skeletal systems appear most frequently, along with sensory organs and basic endocrine functions.

How many bones are there in the human body, and is this commonly asked?

Yes, the human body has 206 bones, and questions about the largest, smallest, and total bone count appear fairly often.

What kind of blood-related questions come up in SSC CGL?

Questions usually cover blood group compatibility, the role of platelets in clotting, and basic facts about blood pressure and heart function.

Do I need detailed biochemistry knowledge for the human body section?

No, most questions focus on what each organ does and why, rather than the detailed biochemical processes behind it.

How can I retain human body facts more effectively for the exam?

Linking facts to real-life observations, like why pulse is checked at the wrist, makes them easier to recall than memorizing textbook lines.
