Chapter 47.1, Problem 5R
Summary Introduction
To review:
The reason behind the importance of gap junctions in smooth and cardiac muscles and not in skeletal muscles.
Introduction:
The gap junctions consist of small interconnections between the cells. Channel proteins like connexons help in the connection of gaps of one cell to other, which result in the direct communication of the cells. The direct communication is important in smooth and cardiac muscle cells. In case of plants, the cells are connected by plasmodesmata.
