    • ‘In nulliparous women, in the upright position, their long axis is vertical; it has lateral and mesial surfaces, tubal and uterine extremities and mesovarian and free borders.’
    • ‘The findings suggest that damage to the right mesial prefrontal cortex causes abnormal hoarding behavior by releasing the primitive hoarding urge from its normal restraints.’
    • ‘The most common type is mesial impaction, which means teeth that have grown at an angle facing towards the front of the mouth.’
    • ‘Branches of the cingulum curve around outside the trigon on its mesial and distal sides.’

    • ‘This may be due in part to the fact that the most common pathologic finding of temporal lobe resections involve hippocampal or mesial temporal sclerosis and neoplasia.’
    • ‘It has been postulated that mesial temporal sclerosis may be related to a complicated delivery, febrile convulsions during childhood, and status epilepticus.’
    • ‘The molars tend to interlock with their mesial and distal neighbors in ways which become more elaborate and precise in later forms.’
    • ‘Damage to this area - the right mesial prefrontal cortex - apparently causes the near-universal interest in collecting to escalate out of control by releasing the primitive hoarding urge from its normal restraints.’
    • ‘The most common finding was mesial temporal sclerosis, which is typically not detected on CT.’
    • ‘By rolling the labial margins toward the midline, the mesial end of the upper dentition can be narrowed without bringing the plates out of line.’
