    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
