Pain and temperature sensations are mainly transmitted by:
Go with C — Aδ and C fibers. Within Neuron; Structure and Function, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, the functional job described in the stem is exactly what Aδ and C fibers does in Neuron; Structure and Function. Holding that picture in mind makes Aδ and C fibers feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Aδ and C fibers.
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.
