Study Notes
Nervous and Endocrine Systems
- The nervous system utilizes neurotransmitters as chemical messengers to communicate rapidly between neurons.
- The endocrine system employs hormones as chemical messengers, coordinating longer-term bodily functions across various systems.
Functions of Hormones
- Hormones regulate numerous processes including metabolism, growth, reproduction, and mood.
- They play crucial roles in maintaining homeostasis and affecting almost every cell in the body.
Hormonal Transport
- Hormones are secreted into the bloodstream, enabling them to travel throughout the body to reach target organs and tissues.
- Hormonal signaling can affect distant tissues unlike neurotransmitters which typically exert influence in nearby synapses.
Communication Speed Comparison
- Neurotransmitters communicate quickly (within milliseconds), allowing for immediate responses, such as muscle contractions.
- In contrast, hormones are slower-acting, often taking seconds to hours to exert their effects due to reliance on blood circulation and receptors' activation.
