<span>The health triangle is made up of the 3 elements of health; physical, mental/emotional, and social. It shows us how things affect us in each aspect, and shows us how we need to try to balance these aspects in our life. It is so difficult for individuals to actually obtain this balance, called wellness, because we constantly have so much going on in our lives and we can't always keep everything balanced.</span>
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.
