Which intercalated disk/interdigitating junction has keratin?
|
|
desmosomes
|
|
|
fascia adherens
|
|
|
gap junction
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Cardiac muscle cells are equipped with three distinct types of intercellular junction–gap junctions, “spot” desmosomes, and “sheet” desmosomes (or fasciae adherentes)–located in a specialized portion of the plasma membrane, the intercalated disk.
Detailed explanation-2: -Intercalated discs are part of the cardiac muscle sarcolemma and they contain gap junctions and desmosomes.
Detailed explanation-3: -Intercalated disks represent the undulating double membranes where two cells are tightly bound together by desmosomes and connected by gap junctions, allowing electrical impulse conduction from cell to cell.
