Detailed explanation-1: -This method of communication allows cells to coordinate movement and activity with their neighbors. An example of this is called synaptic signaling. That’s when signaling occurs across the tiny gap between two neurons.

Detailed explanation-2: -Cell signaling (also called signal transduction) describes the ability for cells to respond to stimuli from their environment. Some examples include wound healing after injury, activation of the immune system in response to pathogens, and changes in gene expression during different developmental stages.

Detailed explanation-3: -This type of signaling, in which cells communicate over relatively short distances, is known as paracrine signaling. Paracrine signaling allows cells to locally coordinate activities with their neighbors.

Detailed explanation-4: -Synaptic signaling is similar to paracrine signaling but there is a special structure called the synapse between the cell originating and the cell receiving the signal. Synaptic signaling only occurs between cells with the synapse; for example between a neuron and the muscle that is controlled by neural activity.
