Which type of signaling occurs between neighboring cells with neurotransmitters?

Paracrine signaling is characterized by cell-to-cell communication through the release of signaling molecules, such as neurotransmitters, which act on nearby cells. This type of signaling is crucial for processes that require localized responses, such as the transmission of signals between neurons across synapses. In the case of neurotransmitter signaling, a neuron releases neurotransmitters into the synaptic cleft, which then bind to receptors on adjacent neurons, facilitating rapid and specific communication between them.

Endocrine signaling, in contrast, involves the release of hormones into the bloodstream, where they can have widespread effects on distant target cells. Autocrine signaling occurs when a cell releases a signaling molecule that binds to receptors on its own surface, thereby affecting itself. Exocrine signaling involves the release of substances through ducts to external environments, such as saliva in the mouth or digestive enzymes in the gut.

In summary, paracrine signaling is specifically tailored for communication between neighboring cells via neurotransmitters, making it the correct answer in this context.
