Block 7: The Endocrine & Digestive System Terms To Know Flashcards
Nervous vs Endocrine Control
Similarities
- communication is a two way street: brain to body & body to brain
- act together to control and coordinate body activities
- usage of chemical messengers for intercellular communication
Differences
- endocrine system:
a. messages are hormones
b. slow transmission and longer lasting effects
- nervous system:
a. messages are neurotransmitters and action potentials
b. faster transmission and shorter lasting effects
