In terms of tissue type, the body may be analyzed into water, fat, connective tissue, muscle, bone, etc. In terms of cell type, the body contains hundreds of different types of cells, but notably, the largest number of cells contained in a human body (though not the largest mass of cells) are not human cells, but bacteria residing in the normal ...
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
Docosahexaenoic acid (DHA) is an omega−3 fatty acid that is an important component of the human brain, cerebral cortex, skin, and retina. It is given the fatty acid notation 22:6( n −3) . [ 1 ] It can be synthesized from alpha-linolenic acid or obtained directly from maternal milk (breast milk), fatty fish, fish oil, or algae oil.
Kidney and nerve tissue cells can form memories much like brain cells, one new study has found. Another recent study says that memories of obesity stored in fat tissue may be partly responsible ...
The brain-mapping project opens the door for future investigations, according to neuroscientist Olaf Sporns. “Each human brain is a vast network of billions of nerve cells,” said Sporns ...
After strict fasting for 3 days, the brain gets 25% of its energy from ketone bodies. [14] After about 24 days, ketone bodies become the major fuel of the brain, making up to two-thirds of brain fuel consumption. [15] Many studies suggest that human brain cells can survive with little or no glucose, but proving the point is ethically ...
Visceral fat is key. A pilot study by Raji and his team, released in November 2023, found a type of deep abdominal fat called visceral fat, was linked to inflammation and amyloid buildup in the ...
In the central nervous system (brain, spinal cord and optic nerves), myelination is formed by specialized glial cells called oligodendrocytes, each of which sends out processes (limb-like extensions from the cell body) to myelinate multiple nearby axons; while in the peripheral nervous system, myelin is formed by Schwann cells (neurolemmocytes ...
