Question

junctions in the epithelium which facilitate the cell to communicate with neighbouring cells are (a) adhering junctions (b) gap junctions (c) tight junctions (d) compound junctions

Answer 1

Heya..!

communication at level of cells is possible by chemical exchange between cells.. this is possible by GAP JUNCTIONS.

So, the answer is B) Gap junctions

Let's see some types of junctons in detail.

TIGHT JUNCTIONS
Plasma membranes in the apical part of the adjacent epithilial cells become tightly packed together or are even fused to form the tight junctions. They check the flow of materials between the cells.

GAP JUNCTIONS
These are meant for chemical exchange between adjacent cells.

ADHERING JUNCTIONS
They perform cementing functions to keep neighbouring cells together.
