Document Summary

Motor: facial motor nucleus and bump on peduncle caused by the 7th cn. Medial longitudinal fasciculus local connection: which connects other sections in brainstem. Two characteristic features of the pons are visible on the histological section. The first is the connection to the cerebellum via the middle cerebellar peduncle. The second is the patchy appearance of the corticospinal tracts at this level, with fibres in between pontine nuclei (the corticospinal fibres would extend into and out from the screen). The basilar artery can usually be seen ventral to the pons (the dark circle on. Partial thrombosis of basilar artery on ventral surface of pons can occlude multiple perforating arteries and cause infarction of the ventral pons (half of which is shaded in orange). Corticospinal tracts (umn to limbs), corticobulbar tracts (umn to vi and vii), and the mlf (communication to iii for lateral gaze) are all damaged bilaterally.
