Question

1. : Help prevent molecules from passing through the extracellular space between adjacent cells.

Answer 1

Answer:(1) TIGHT JUNCTIONS

(2) DESMOSOMES

(3) GAP JUNCTIONS

(4) GAP JUNCTIONS

(5) DESMOSOMES.

Explanation: TIGHT JUNCTIONS also known as OCCLUDING JUNCTIONS are junctions present between adjacent cells,tight junctions prevent the passage of materials between the extracellular space of cells.

DESMOSOMES are adhesive intracellular junction connecting adjacent cells,they are also known as anchoring joints which are known to present in tissues where stress are expected.

GAP JUNCTIONS are junctions between cells which allows the movement of ions and small molecules and present in electrically exciteable tissues.
