#vagus nerve MCQ

2 public questions tagged with this topic.

Which cranial nerve is longest and mixed in nature?

Pick C: Vagus. Thinking about Peripheral Nervous System in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: Vagus is the option that correctly names the structure, process, or principle asked for in Peripheral Nervous System. Hence Vagus is correct. Treat this as a building block for the rest of Peripheral Nervous System; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Vagus.

Ref: Animal physiology is Unit 7 of the CSIR NET Life Science Syllabus, covering core body systems. It accounts for roughly 10% of the total marks in Sections B and C.

Vagus nerve primarily supplies:

Correct option is C, Thoracic and abdominal viscera. In Peripheral Nervous System, the accurate description is Thoracic and abdominal viscera, and that is what you should commit to memory. Keep the definition tight and the role clear — the functional job described in the stem is exactly what Thoracic and abdominal viscera does in Peripheral Nervous System. Then Thoracic and abdominal viscera is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Thoracic and abdominal viscera.
