As Jerry nears the campfire, he is delighted at the warmth it provides. Jerry perceives this temperature because of thermoreceptors in his skin.
<h3>What are thermoreceptors?</h3>
- The receptive part of a sensory neuron, or more precisely a non-specialized sense receptor called a thermoreceptor, is responsible for coding absolute and relative changes in temperature, primarily those that fall within a safe range.
- Warmth sensors are assumed to be unmyelinated C-fibers in the mammalian peripheral nervous system (low conduction velocity), whereas cold receptors have both C-fibers and sparsely myelinated A delta fibers.
- Warm receptors respond well to warming, which causes them to discharge action potentials more quickly.
- For cold sensors, cooling causes an increase in firing rate whereas warming causes a reduction.
- A paradoxical reaction to heat is when some cold receptors react to high temperatures, usually above 45 °C, by releasing a short action potential.

Plants are autotrophs because they carry out photosynthesis and produce food for themselves.
<span>Fungi does not contain chlorophyll or carry out photosynthesis, which is why you can find a lot of fungi in dark places. Fungi takes its nutrients from dead organic matter, which is why you would find fungi on rotten fruits and dead animals.</span>
When the work performed by the muscular system present in the heart is interrupted by various factors, damage would primarily result from decreased delivery of oxygen.
<h3>What is cardiac muscle?</h3>
It is the muscle tissue of mixed components, which is located exclusively in the walls of the heart.
When the heart is deprived of its normal blood supply, it can cause irreversible tissue damage by disrupting the pathways that carry oxygen to muscle cells.
Therefore, we can conclude that the heart is a vital organ that is made up of specialized tissues and cells, , damage would primarily result from decreased delivery of oxygen.
