Word Origin & History

pons 
"bridge," in various L. expressions, esp. pons asinorum "bridge of asses" (1751), nickname for the fifth proposition of the first book of Euclid, which beginners and slow wits find difficulty in "getting over": if two sides of a triangle are equal, the angles opposite these sides are also equal. From PIE *pent- "to go, to pass; path, bridge" (cf. Skt. panthah "path, way," Gk. pontos "open sea," pateo "I step").

Vaároálio /vä-'rO-lE-O/, Costanzo (1543–1575), Italian anatomist. A surgeon andprofessor of anatomy at Bologna, Varolio is remembered for his work on the cranial nerves. In 1573 he published a work which described his new method of dissecting the brain: he separated the brainfrom the skull and began the dissection from the base. This method allowed for better observation of the structures of the brain, especially the cranial nerves. As a result of his improved method ofdissection, he was able to observe and describe for the first time the mass of nerve fibers that is now known as the pons Varolii. His method also allowed him to add to the knowledge of the course andterminations of the cranial nerves in the brain.

A thick band of nerve fibers in the brainstem of humans and other mammals that links the brainstem to the cerebellum and upper portions of the brain. It is important in the reflex control of involuntary processes, including respiration and circulation. All neural information transmitted between the spinal cord and the brain passes through the pons.
