The brainstem (medulla, pons, and midbrain) controls vital involuntary functions like breathing, heart rate, and digestion.

The trachea is supported by incomplete cartilaginous rings that prevent its collapse during breathing.

The larynx, also known as the voice box, contains vocal cords responsible for sound production.

The pleural membranes surround the lungs and reduce friction during breathing by secreting pleural fluid.

Bronchioles do not have cartilaginous rings; instead, they are composed of smooth muscle, which allows them to constrict or dilate.

Pick B: Mucosa → submucosa → muscularis → serosa. Thinking about Digestive 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: Mucosa → submucosa → muscularis → serosa is the option that correctly names the structure, process, or principle asked for in Digestive System. Hence Mucosa → submucosa → muscularis → serosa is correct. Treat this as a building block for the rest of Digestive 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.
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.
Correct option is B, Protection and limited secretion. In Tissue-I, the accurate description is Protection and limited secretion, 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 Protection and limited secretion does in Tissue-I. Then Protection and limited secretion 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 Protection and limited secretion.
