Thermogenesis – Types of Thermogenesis

Thermogenesis – Types of Thermogenesis

Hi Seekers !
Today we will be discussing about Thermogenesis.

What is Thermogenesis? 

As we all know that thermogenesis is a process of heat production in organism. It mainly occurs in warm-blooded animals what we called as endo thermos. As they are able to regulate their body temperature irrespective of the environment attempt temperature.

What are the two categories of thermogenesis? Or What are different types of thermogenesis?

So, this thermogenesis is subdivided into two categories ;

1.Shivering
2.Non shivering

Shivering involves some physical movements by our contracting muscles it does not involve any brown fat but involves white fat. Sometimes, it occurs in endotherms as already told you that the warm-blooded animals. However, On the other hand we have the non shivering, it is a biochemical process. It is a cellular mechanism that occurs inside death cell it occurs in youth aliens involves brown fat. This brown fat has a very interesting feature that has lot of mitochondria in it by which there is a heat generation. We will discuss it later on but in this post we’ll be discussing about shivering only. So, we can know that shivering is a path of thermogenesis. And moreover we can also say that it’s a process of heat generation and/or thermals second thing is that it’s in response to the early hypothermia and third most important thing is that it involves their homeostasis that means this shivering is a part of homeostasis because we maintain the body temperature in it.

 So we called it homeostasis that’s the stabilizing part of the human body temperature. Now, we will see how this homeostasis occurs in our body because we have stabilized the temperature when there is pollen temperature we see we have a body at normal temperature when there is a decrease in temperature in the environment this sensation is taken by our cold receptors that means this decreasing temperature is censured by the cold receptors and these cold receptors that are in the form of pebbles they send the signal to our brain mainly the hypothalamus because hypothalamus is a thermal regulatory part of our brain and then brain sends back signal. Basically, it sends back the signal in the form of petals like we have the glitches we have the contraction of muscles and other things secretion of some hormone that means these effectors regulate the body temperature to Normal and we get the body at normal temperature back again same process happens for when there is increase in temperature.

So, we can say that the same happens for cooling the body too. Now, we will see the mechanism of shooting in detail there is a decreasing temperature is censored by cold receptors as we already told you!

What are cold receptors actually?

Now, what are these cold receptors cold receptors or sea pebbles and a data fibers in our nervous system. First, they are unmyelinated fibers. They have the low conduction velocity then a delta pebble, they are myelinated fibers in our nervous system and have the first conduction velocity then sea pebbles where CN delta pi balls and DC and a delta velocity or senses the cold outside our body and transmits a signal to the spinal cord through a tried cold laser straight line as a stride transmitter signal to the brain through lateral para brachial nucleus just natural para bailar nucleus transmitters again the signal to the preoptic area in the hypothalamus which is the thermal regulator area.

Now, we will see how the effect occurs this optic area in hypothalamus sends signal to anterior hypothalamus of nucleus because it helps in cooling. So until your hypothermic nucleus again sends the signal to the postern nucleus this poster Nucleus is the effector area for heating. It gives the effector response in the form of Shivering and boss of construction and in this shivering the muscles keep rapidly contracting and relaxing to generate heat to produce heat because there is a conversion of chemical energy of ATP into kinetic energy causing some of the energy to show up as a heat but on the other hand we have also addition hormone which is released by the contracting muscles and this addition hormone which is also called excise hormone has some amazing function ensuring process can take on the white fat to take on characteristics or brown fat which is able to generate energy and generate heat.
