Current Question (ID: 13746)

Question:

Match the columns. Column 'A' (a) Tight junctions (b) Gap junctions (c) Inter digitations (d) Adhering junctions Column 'B' (i) Macula adherens (ii) Stop substances leaking in columnar epithelium (iii) Common in transitional epithelium (iv) Rapid transfer of ions and molecules

Options:

1. a i, b ii, c iii, d iv
2. a ii, b iv, c iii, d i
3. a ii, b iv, c i, d iii
4. a ii, b i, c iii, d iv

Solution:

Tight junctions stop substances leaking in columnar epithelium. Gap junctions allow rapid transfer of ions and molecules. Inter digitations are common in transitional epithelium. Adhering junctions are also known as macula adherens.
