The ependyma is the thin neuroepithelial (simple columnar ciliated epithelium) lining of the ventricular system of the brain and the central canal of the spinal cord. [1] The ependyma is one of the four types of neuroglia in the central nervous system (CNS).
Poor diet in early childhood affects the number of neurons in parts of the brain. [1]Nutritional neuroscience is the scientific discipline that studies the effects various components of the diet such as minerals, vitamins, protein, carbohydrates, fats, dietary supplements, synthetic hormones, and food additives have on neurochemistry, neurobiology, behavior, and cognition.
Neuroinflammation is widely regarded as chronic, as opposed to acute, inflammation of the central nervous system. [5] Acute inflammation usually follows injury to the central nervous system immediately, and is characterized by inflammatory molecules, endothelial cell activation, platelet deposition, and tissue edema.

The human nervous system consists of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord . The PNS consists mainly of nerves , which are long fibers that connect the CNS to every other part of the body.
Cerebral hyperaemia is a fundamental central nervous system mechanism of homeostasis that increases blood supply to neural tissue when necessary. [3] This mechanism controls oxygen and nutrient levels using vasodilation and vasoconstriction in a multidimensional process involving the many cells of the neurovascular unit, along with multiple ...
A specific type of body fat — visceral fat — around the midsection has been linked to the abnormal proteins that develop in the brain and are a hallmark of Alzheimer’s, according to findings ...
The brain is the central organ of the human 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 ...
“A stroke occurs when the central nervous system is injured due to a vascular cause, so that could be due to a blockage, which accounts for about 80% of strokes in the United States, or a ...
