Endocrine Signaling:

This involves hormones being secreted into the bloodstream by certain glands, where they can reach cells throughout the body.

Paracrine Signaling:

This is when cells produce signals that affect nearby cells. It's like whispering a message to your neighbor.

Juxtacrine Signaling:

In this type of signaling, messages are passed directly from one adjacent cell to another through contact or shared junctions. It's like passing a note hand-to-hand in class.
