What is local signaling? What is an example of this?

What are hormones? What type of signaling are they involved in?

Define: Ligand –

Target cell –

Are signal receptors general (will they bind a variety of different signals) or are they very specific?

Where are intracellular receptors found?

What types of molecules bind to intracellular receptors? Why must these signals have those characteristics?

When a cell surface receptor receives a signal, what generally happens to the receptor? Use the ion-gated receptors as an example.
