What structure in cardiac muscle facilitates communication between cells?
Understand the Problem
The question asks which structure in cardiac muscle is responsible for facilitating communication between the cells. It presents four options related to muscle structure.
Answer
Intercalated disc
The structure in cardiac muscle that facilitates communication between cells is the intercalated disc.
Answer for screen readers
The structure in cardiac muscle that facilitates communication between cells is the intercalated disc.
More Information
Intercalated discs in cardiac muscle consist of gap junctions, desmosomes, and adherens junctions. They are crucial for electrical and mechanical coupling, ensuring synchronized heart contractions.
Tips
A common mistake is to confuse gap junctions as the sole structure for communication. However, intercalated discs encompass gap junctions along with other components.
