The eicosanoid hormones are ___________ hormones, secreted into the interstitial fluid (not primarily into the blood) and acting on nearby cells. A: endocrine B: autocrine C: paracrine D: neuroendocrine

Which of the following forms of cell-to-cell communication would allow one cell to directly affect a cell the furthest distance from it? A: juxtacrine signals B: hormones C: paracrine factors D: immune synapses

In __________________ signaling, a cell-surface-bound signal molecule binds to a receptor protein on an adjacent cell. During embryonic development, for example, such signaling method allows adjacent cells that are initially similar to become specialized to form different cell types. A: endocrine B: contact-dependent C: paracrine D: neuronal

There are two major participants in every cell communication activity. The one that is giving communication, and the one that receives communication. Some also communicate through direct and indirect contact, which is also called local and long-distance signaling. Which of the following is an example of long-distance signaling occurring in the body? A: paracrine signaling B: systematic signaling C: synaptic signaling D: hormonal signaling
