    Experimental response: Application of the chemical directly to the target cells should produce the same response observed when the chemical is naturally released from neurons. Removal mechanism: There must be a mechanism in place to remove the neurotransmitter from its site of action once its signaling role is complete.

  3. Cell signaling - Wikipedia

    en.wikipedia.org/wiki/Cell_signaling

    Autocrine signaling involves a cell secreting a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell itself. [13] This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.

    Using these chemical messengers, they can react to the environment and assess the best growth pattern. [19] Essentially, plants grow to optimize their metabolic efficiency. Humans also rely on chemical messengers for survival. Epinephrine, also known as adrenaline, is a hormone that is secreted during times

  5. Chemical messenger - Wikipedia

    en.wikipedia.org/wiki/Chemical_messenger

    A chemical message is any compound that serves to transmit a message, and may refer to: Hormone, long range chemical messenger; Neurotransmitter, communicates to adjacent cells; Neuropeptide, a protein sequence which acts as a hormone or neurotransmitter. The blood or other body fluids transport neuropeptides to non adjacent target cells, where ...

    Autocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell.

  7. Chemical synapse - Wikipedia

    en.wikipedia.org/wiki/Chemical_synapse

    Chemical synapses are biological junctions through which neurons' signals can be sent to each other and to non-neuronal cells such as those in muscles or glands. Chemical synapses allow neurons to form circuits within the central nervous system. They are crucial to the biological computations that underlie perception and thought.

  9. Neurosecretion - Wikipedia

    en.wikipedia.org/wiki/Neurosecretion

    Neurosecretion is the release of extracellular vesicles and particles from neurons, astrocytes, microglial and other cells of the central nervous system.These neurohormones, produced by neurosecretory cells, are normally secreted from nerve cells in the brain that then circulate into the blood.
