Cell Communication Vocab Flashcard #1 Dec 2

Front

What is juxtacrine signaling?

Back

Cell signaling for cells that touch at least temporarily.

Front

What is paracrine signaling?

Back

Type of cell signaling between cells near one another.

Front

What are antigens?

Back

Cellular ID badges/tags that help the immune system recognize foreign substances.

Front

How do endocrine signals travel?

Back

Endocrine signals use blood vessels for their avenue of transportation.

Front

What are plasmodesmata?

Back

Channels between plant cells that allow for fast communication to adjoining plant cells.

Front

What is autocrine signaling?

Back

Cell signaling where a cell targets itself.

Front

What is the role of hormones in cell communication?

Back

Hormones are signaling molecules that travel through the bloodstream to target distant cells.

Front

What is the difference between endocrine and paracrine signaling?

Back

Endocrine signaling involves long-distance communication via blood vessels, while paracrine signaling involves communication between nearby cells.

Front

What are gap junctions?

Back

Specialized intercellular connections that allow direct communication between adjacent cells.

Front

What is the function of MHC molecules?

Back

MHC (Major Histocompatibility Complex) molecules present antigens on the surface of cells to help the immune system recognize them.
