The receptive field of an individual sensory neuron is the particular region of the sensory space (e.g., the body surface, or the visual field) in which a stimulus will trigger the firing of that neuron.

The visual cortex of the brain is a part of the cerebral cortex that plays an important role in processing visual information.

The composition of the human body can be looked at from the point of view of either mass composition or atomic composition.

12-Hydroxyeicosatetraenoic acid (12-HETE) is a derivative of the 20 carbon polyunsaturated fatty acid, arachidonic acid, containing a Hydroxyl residue at carbon 12 and a 5Z,8Z,10E,14Z Cis–trans isomerism configuration (Z=cis, E=trans) in its four double bonds.

5-Hydroxyicosatetraenoic acid (5-HETE, 5(S)-HETE, or 5S-HETE) is an eicosanoid, i.

5-Oxo-eicosatetraenoic acid (i.e. 5-oxo-6E,8Z,11Z,14Z-eicosatetraenoic acid; also termed 5-oxo-ETE and 5-oxoETE) is a Nonclassic eicosanoid metabolite of arachidonic acid and the most potent naturally occurring member of the 5-HETE family of cell signaling agents.

Hepoxilins (Hx) are a set of epoxyalcohol metabolites of polyunsaturated fatty acids (PUFA), i.

Hyperchlorhydria, sometimes called chlorhydria, refers to the state in the stomach where gastric acid levels are higher than the reference range.
