The basilar part of pons is the ventral part of the pons, the dorsal part is known as the pontine tegmentum

Clinical significance[edit]

Tissue death (infarction), in this region can impair motor functioning.[1] A lacunar stroke of the base of the pons is known to cause contralateral dysarthria-clumsy hand syndrome.

The basis pontis undergoes demyelination in the condition known as central pontine myelinolysis. This condition is due to the rapid intravenous correction of hyponatremia.
