Question

which of the following types of signaling is represented in this figure below?
target cell
autocrine
paracrine
hormonal
synaptic

Explanation:

Synaptic signaling involves the release of neurotransmitters from a neuron (like the structure in the figure) to a target cell (such as another neuron or muscle cell). Autocrine is when a cell signals itself. Paracrine is short - range signaling between nearby cells (not involving a neuron - like structure as shown). Hormonal signaling uses the bloodstream for long - range transport. The figure shows a neuron - like cell releasing signals (neurotransmitters) to a target cell, which is characteristic of synaptic signaling.

Answer:

synaptic
