Mindblown: a blog about philosophy.

A free radical gas produced endogenously by a variety of mammalian cells. It is synthesized from arginine by a complex reaction, catalyzed by nitric oxide synthase. Nitric oxide is endothelium-derived relaxing factor. It is released by the vascular endothelium and mediates the relaxation induced by some vasodilators such as acetylcholine and bradykinin. It also inhibits…

An analgesic and anti-inflammatory agent used in the treatment of rheumatoid arthritis.  

A trace element with the atomic symbol Ni, atomic number 28, and atomic weight 58.69. It is a cofactor of the enzyme urease. A mineral that may or may not be essential to humans. It is needed in trace amounts by growing chicks. Nickel is a micromineral about which relatively little is known. Foods that…

The process in which the neutrophil is stimulated by diverse substances, resulting in degranulation and/or generation of reactive oxygen products, and culminating in the destruction of invading pathogens. The stimulatory substances, including opsonized particles, immune complexes, and chemotactic factors, bind to specific cell-surface receptors on the neutrophil.  

Electrically neutral elementary particles found in all atomic nuclei except light hydrogen; the mass is equal to that of the proton and electron combined and they are unstable when isolated from the nucleus, undergoing beta decay. Slow, thermal, epithermal, and fast neutrons refer to the energy levels with which the neutrons are ejected from heavier…

An act or process of neutralizing. In pathology, the binding of an antibody to an antigen in such a way that the antigen is no longer harmful. The opposing of one force or condition with an opposite force or condition to such degree as to cause counteraction that permits neither to dominate.

Referring to a nerve or the nervous system. Situated in the region of the spinal axis, as the neutral arch. Pertaining to any part of the nervous system. To nerves or the nervous system.    

Pertaining to a nerve or to the nerves, a meshlike structure of interlocking fibers or strands. In a communications system, an orderly arrangement of stations interconnected through communications channels that form a coordinated entity. An interconnecting system of lines and spaces, like a net. Interconnected or intersecting configuration, system of people, or components. Anatomically, the…

The entire nerve apparatus composed of the brain, spinal cord, nerves and ganglia. Comprised of the brain, spinal cord, nerves, and the sense organs, it serves as the control center and communication network within the body. A system of microscopic cells that specialize in the conduction of impulses and are located in the central nervous…
