This is an example of

• short distance signaling

• long distance endocrine signaling

• self signaling

• direct contact signaling

Secret substances that only affect the cell that is secreting the substance

• self signaling

• direct contact signaling

• short distance signaling

• long distance signaling

Secret substances into interstitial fluid but affect only nearby cell

• self signaling

• long distance signaling

• direct contact signaling

• short distance signaling

Type of cell signaling where the ligand is released and will affect cells in its "neighborhood"

• self signaling

• direct contact signaling

• short distance signaling

• long distance endocrine signaling

Type of cell signaling where the ligand is produced at a location distant from its target cell(s)

• self signaling

• direct contact signaling

• short distance signaling

• long distance signaling

What type of cell signal is shown in the figure to provide communication, affecting nearby cells in the same tissue or area?

• self

• direct contact

• short distance

• long distance

Neurons release acetylcholine (ACh) into the gap between the nerve cell and a muscle cell. ACh then binds to receptors in the muscle cell membrane, resulting in the release of Ca²⁺ from the smooth ER
