cell biology

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

Are these exam questions?

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.
