MICROANATOMY

Detailed explanation-1: -Brown adipose tissue (BAT) contributes to non-shivering thermogenesis and plays an important role in the control of body temperature [4, 5, 10]. The thermogenic function of BAT is mediated by uncoupling protein 1 (UCP1), which is located in the mitochondrial inner membranes of brown adipocytes.

Detailed explanation-2: -Brown fat is responsible for producing heat to warm the blood in your body. You’ll notice brown fat burning right before you start to shiver because the fat activates (turns on) in cold temperatures. It produces heat by breaking down blood sugar (glucose) and molecules of fat.

Detailed explanation-3: -Brown fat, or brown adipose tissue, is a distinct type of fat that is activated in response to cold temperatures. Its primary role is to produce heat to help maintain body temperature, and it achieves that by burning calories.

Detailed explanation-4: -The sensation of cold causes sympathetic nerves to release catecholamines in BAT that stimulate proliferation and heat production by brown fat cells (2).
