Question

Quizplus · Accepted Answer

Desmosomes are intercellular junctions that act as rivets, anchoring adjacent cells together at spots throughout the cell. They are commonly found in tissues that experience mechanical stress, such as skin and heart muscle. Focal adhesions, adherens junctions, and hemidesmosomes also serve to anchor cells, but they do not act as rivets in the same way that desmosomes do. Fibronectin is a glycoprotein that is a component of the extracellular matrix and can bind to integrin receptors to facilitate cell adhesion, but it does not directly anchor adjacent cells together.
