Cell Connections - How Are Cells Connected - What Are Cell Junctions - Types Of Cell Connections

What are the three main types of cell connections discussed?

• Desmosomes, gap junctions, and tight junctions

• Spot welds, protein plaques, and filaments

• Plasma membranes, cells, and proteins

• Intermediate filaments, connexons, and hemidesmosomes

What is the main function of spot desmosomes?

• They allow substances to pass between cells.

• They prevent substances from passing between cells.

• They hold adjacent cells together like spot welds.

• They connect cells to other body structures.

What do gap junctions allow to pass between cells?

• Only large proteins

• Only water molecules

• Certain substances and impulses

• Nothing at all

How do tight junctions help protect other body structures?

• They allow cells to easily share nutrients.

• They prevent substances from leaking between cells.

• They connect cells to the cytoskeleton.

• They form strong, flexible belts around cells.
