A
Signal

Response
5
Q
What are autocrines?
A
Signals affect the cells that made them
6
Q
What are juxtacrines?
A
Signals affect the cells adjacent to the cells that made them
7
Q
What are paracrines?
A
Signals affect the cells nearby the cells that made them
8
Q
What are hormones/endocrines?
A
Signals affect that are a long distance from the cells that made them
They generally travel to distant cells via the circulatory system
