What are some examples of endocrine, autocrine, and paracrine signaling?
Autocrine signaling is when a cell sends signals to itself, paracrine signaling is when neighboring cells signal to each other, and endocrine signaling is when cells, via hormones, relay messages throughout the body.
An example of endocrine signaling includes the hypothalamic-pituitary-adrenal (HPA) axis.
- Hypothalamus produces CRH
