Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
true or false:sinusoids has intercellular gaps and fewer tight junctions, allowing for the passage of larger molecules
A
T
B
F
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Gap junctions are communicating junctions composed of clusters of connexons that allow molecules smaller than about 1000 daltons to pass directly from the inside of one cell to the inside of the next.

Detailed explanation-2: -Gap junctions The cytoplasms of the cells are connected by narrow water-filled channels. These channels allow passage of small signalling molecules such as calcium and cyclic AMP, but not of large molecules such as proteins.

Detailed explanation-3: -Intercellular adhesion complexes Two types of intercellular junctions are established at the level of the lateral surface of epithelial cells: tight junctions (TJs) and adherens junctions (AJs).

Detailed explanation-4: -Answer and Explanation: Gap junctions are the specialized cell communication channels between adjacent or neighboring cells. The function of the gap junctions is to directly connect the cytoplasm of two cells. These channel allows the movement of molecules, electrical impulses, and ions between the connected cells.
