    In many ways cells communicate the way human communicate with each other. Define the following forms of human communication by classifying them as pararine, endocrine and/or synaptic signaling:

    A telephone conversation

    Talking to people at a cocktail party

    a radio announcement

    talking to oneself

    These are obviously homework questions...I must say wildgrass you are doing a great job at answering them. Too bad for this poster is learning absolutely nothing. Wormer: You could at least try to ask about the parts you are not understanding, as oposed to just outright asking the entire question as posed. I mean come'on...

    a cell produces a signal to induce changes in nearby cells
    paracrine factors diffuse over a relatively short distance (local action)
    endocrine factors (hormones which travel considerably longer distances via the circulatory system)
    a synapse[1] is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron

    So! Self-talk, people-talk, phone-talk, radio-speak. Synaptic, paracrine, endocrine, and then we need another babble word? I don't see how any of this is useful.

    thanks you for the explination. I forghot that autocrine was an option as well. It all makes sense now

    denoting a mode of hormone action in which a hormone binds to receptors on and affects the function of the same cell that produced it.

    Yes, all is clear now.
