The MNTN is located in the brainstem, more specifically (sources vary) spanning the length of the midbrain [2] /in the caudal midbrain and rostral pons. [1] It is situated (sources vary) near [ 1 ] /within [ 2 ] the periaqueductal gray , lateral to the cerebral aqueduct .

This photo shows teeth #2-5 (Universal numbering system). Tooth #3, the upper right first molar, has an MO (mesial-occlusal) gold inlay. This molar is both posterior, as well as distal, to the premolars in front of it. Most of the principal terms can be combined using their corresponding combining forms (such as mesio-for mesial and disto-for ...
The dentate forms the largest pathway between the cerebellum and the remainder of the brain.
