Also called the pons Varolii, the pons is a structure located in
the lower brainstem just above the spinal cord, and bulging forward
in front of the cerebellum, from
which it is separated by the fourth ventricle. It consists of a thick
bundle of nerve fibers that links the medulla
oblongata to the thalamus. From
its front surface the trigeminal
nerve emerges. The pons serves as a major pathway for motor and
sensory information between the body and higher level brain functioning.
- A pons is also any portion of tissue that joins two parts of an organ.
