Thermal insulation by adipose tissue

... would not operate at all at lower temperatures. One of the major reasons people die from hypothermia is major organ failure. Fat is a good natural insulator, as is air. It is just one of their inherent properties. Adipose tissue is fatty tissue. answer2:Adipose tissue is now recognised as a highly ...

Thermal insulation by adipose tissue

... keep us warm when it is cold. For us humans, clothes serve as the most important way of thermal insulation, and for many land mammals the primary insulator is the fur. However, when you look at the marine mammals you can definitely see the importance of fat as a thermal insulator: whales, seals ...

Thermal insulation by adipose tissue

Well, adipose tissue is known to act as a thermal insulator. 1) Why do body organs need thermal insulation? 2) How does adipose tissue provide it? Is it a property of fat stores or something? Thanks!

Require advice regarding Myelin/VitB12 :D

... demyelination if the deficiency has lasted for a relatively long time, but as far as I know this is quite rare. Anyway, myelin acts as a kind of insulator for neurons, and greatly enhances signalling speed e.g. in motor neurons. Thus demyelination of neurons causes problems in many neural functions ...

The Physics of how the Myelin Sheath actually works.

... WHY action potentials travel faster along a nerve cell when it has a myelinated sheath. It says on wikipedia that the sheath acts like a sort of insulator and dielectric (aren't dielectrics normally conductors though?). Now, a normal nerve cell is a capacitor, sitting at -70 mV when compared ...
