Delta is a type of fibre that transmits signals that are interpreted and perceived as pain.
<h3>
Delta fibres</h3>
A delta fibres (also known as A fibres) are a type of sensory fibre. They respond to cold and pressure stimuli, and as nociceptors, their stimulation is perceived as fast/first pain input. Because they are thinly myelinated, they transmit impulses quicker than unmyelinated C fibres but slower than other, thicker myelinated "A" class fibres.
Structure
They have myelinated axons that are thin (2 to 5 m in diameter) and have a moderate conduction velocity, or speed at which a nerve signal moves (2 to 30 m/s). These nerve fibres make up the afferent portion of the reflex arc that causes the body to "draw away" from noxious stimuli because they are linked to acute (sharp) pain (e.g. retracting your hand away from a hot stove). A part of A fibres is also linked to pressure and temperature perception (also known as "cold receptors" in mammals). Contrarily, slow-conducting, unmyelinated C fibres convey gradual, scorching pain.

Answer:
1. Intervene, as a bystander, by telling the bullies to stop. A pro for this response could be that the bullies listen and stop harassing Tristan, but a con could be that they don't stop and instead target you as well.
2. Another response could be to report the incident to a teacher. A pro to this action could be that the bullies listen to an authority figure and stop bullying Tristan, but a con is that this would take longer than taking immediate action.
3. One final response to this situation as a bystander could be to take Tristan's side. By siding with Tristan the bullies might become disinterested due to Tristan not being alone anymore. A con could be that they'd pick on both you and Tristan.
