The region named the right hypochondrium exists anatomically, but is almost totally under the chest wall. In clinical situations, the parts of the abdominal wall just below the right and left costal margins are referred to as the right and left hypochondriac regions respectively.
There is also a distinct pathway from layer 3 of the EC directly to CA1, often referred to as the temporoammonic or TA-CA1 pathway. Granule cells of the DG send their axons (called "mossy fibers") to CA3. Pyramidal cells of CA3 send their axons to CA1. Pyramidal cells of CA1 send their axons to the subiculum and deep layers of the EC.
The region is conventionally divided into three divisions. CA3a is the part of the cell band that is most distant from the dentate (and closest to CA1). CA3b is the middle part of the band nearest to the fimbria and fornix connection. CA3c is nearest to the dentate, inserting into the hilus.
Among the regions of the abdomen, the hypochondrium is the uppermost part. The word derives from the Greek term ὑποχόνδριος hypokhondrios, meaning "of the soft parts between the ribs and navel" from ὑπό hypo ("under") and χόνδρος khondros, or cartilage (of the sternum). Hypochondria in Late Latin meant "the abdomen". [40]

He coined the term cell (from Latin cellula, meaning "small room" [41]) in his book Micrographia (1665). [42] [40] 1839: Theodor Schwann [43] and Matthias Jakob Schleiden elucidated the principle that plants and animals are made of cells, concluding that cells are a common unit of structure and development, and thus founding the cell theory.
A new study is illuminating how “forever chemicals” can alter our brain cells by impairing the genes that maintain healthy neurons, the cells of our nervous system. Scientists are only ...
Place cell responses are shown by pyramidal cells in the hippocampus and by granule cells in the dentate gyrus. Other cells in smaller proportion are inhibitory interneurons, and these often show place-related variations in their firing rate that are much weaker. There is little, if any, spatial topography in the representation; in general ...
