These cells might also play a critical role in complex object recognition within the visual processing areas of the cortex. [3] Relative to other species, the larger cell size and complexity of pyramidal neurons, along with certain patterns of cellular organization and function, correlates with the evolution of human cognition.

Also at the side of each pyramid there is a pronounced bulge known as an olive. Fibers of the posterior column, which transmit sensory and proprioceptive information, are located behind the pyramids on the medulla oblongata. The medullary pyramids contain motor fibers that are known as the corticobulbar and corticospinal tracts. The ...
An ambitious plan to map all 37 trillion cells in the human body is transforming understanding of how our bodies work, scientists report. The received wisdom said we were built from around 200 ...
Two or more atoms is a molecule, like a dioxide. Many small molecules may combine in a chemical reaction to make up a macromolecule, such as a phospholipid. Multiple macromolecules form a cell, like a club cell. A group of cells functioning together as a tissue, for example, Epithelial tissue. Different tissues make up an organ, like a lung.
Govindas forming a human pyramid to reach the Dahi Handi in Hiranandani Gardens, Mumbai. Human pyramid by the Otago Dancers, at an Otago Highlanders game, May 2012.. A human pyramid is an acrobatic formation of three or more people in which two or more people support a tier of higher people, who in turn may support other, higher tiers of people.
