What is the functional significance of gap junctions?
A)They form a barrier that isolates the basolateral surfaces from deeper tissues.
B)They attach the deepest epithelial cells to the basement membrane.
C)They provide firm attachments between neighboring cells.
D)They strengthen the apical region and prevent leakage.
E)They permit chemical communication (diffusion of ions and small molecules)that coordinates the activities of adjacent cells.

Question

Quizplus · Accepted Answer

Gap junctions are specialized intercellular connections that allow direct communication between cells. They permit the diffusion of ions and small molecules (e.g. second messengers, metabolites) between adjacent cells, allowing for coordinated cellular responses. This type of signaling is important for maintaining tissue homeostasis and coordinating physiological functions.
