If you keep swapping Tight and Adhering in a PYQ, one word can cost you the mark. Think seal, cement, intercom-then remember the job, not the name. Tight junction is the seal: it stops substances leaking across a tissue. Adhering junction is the cement: it mechanically attaches neighbouring cells into a sheet. Gap junction is not a gap that separates cells. It creates direct cytoplasmic communication, allowing rapid transfer of ions and small molecules between adjacent cells. Synaptic junction is different: it sends information to another cell through chemicals. So remember: Gap is direct; synaptic is chemical. In epithelial tissue, the trio is Tight, Adhering, and Gap. Use TAGS: T, Trap leakage. A, Attach cells. G, communicate. S, Signal chemically. Tight stops, Adhering joins, Gap talks, and Synapse signals. That is your NEET Cell Junction code.
