3. The ways that signals are transmitted between animal cells are classified by two criteria – The type of secreting cell – The route taken by the signal in reaching its target

4. Endocrine signaling: – Hormones secreted into blood and travel to target cells – Involved in reproduction, growth and development, homeostasis

5. II. Endocrine Glands and Their Hormones

7. Two main groups of hormones: Lipid soluble (steroids) Water soluble (proteins, peptides, amines) Where is receptor for lipid soluble hormone? Where is receptor for water soluble hormone?
