Question

Intercalated discs between cardiac myocytes have ______________ in abundance.

• A. tight junctions
• B. adherens junctions
• C. gap junctions
• D. both tight and adherens junction

Answer 1

The correct option is C gap junctions

Intercalated discs are unique structural formations found between the myocytes of the heart. They play a vital role in bonding cardiac muscle cells together and in transmitting signals between cells.
They contain gap junctions that facilitate the cells to communicate with each other. These junctions allow the cells to contract as a unit, .i.e., when one cells receives a signal to contract, its neighbours are stimulated to contract.
