Front

What is the primary function of cell communication?

Back

To coordinate and regulate physiological processes.

Front

Define autocrine signaling.

Back

A type of signaling where a cell secretes a signal that binds to receptors on its own surface.

Front

Define paracrine signaling.

Back

A type of signaling where a cell secretes a signal that affects nearby cells.

Front

What is endocrine signaling?

Back

A type of signaling where hormones are released into the bloodstream to affect distant target cells.

Front

What role do receptors play in cell communication?

Back

Receptors bind to signaling molecules and initiate a response in the target cell.
