Study Notes
Hormones
- Chemical substances released by cells into extracellular fluids
- Function to regulate metabolic processes in other cells
- Produced by the endocrine system
Neurotransmitters
- Chemical messengers that transmit signals between neurons
- Cross synaptic gaps to bind to receptor sites on receiving neurons
- Influence the likelihood of generating a neural impulse in the receiving neuron
Comparison: Neurotransmitter vs. Hormone
- Neurotransmitters are part of the nervous system, while hormones are part of the endocrine system
Transmission Methods
- Neurotransmitters transmit signals across the synaptic cleft
- Hormones are transmitted through the bloodstream
Production Sources
- Hormones are produced by endocrine glands
- Neurotransmitters are synthesized by neurons
Speed of Action
- Neurotransmitter action is rapid, occurring in milliseconds
- Hormonal effects can last longer, ranging from seconds to days
Regulation Targets
- Hormones regulate specific target organs
- Neurotransmitters stimulate postsynaptic membranes, affecting adjacent neurons
