| 21. | At the front margin, a cingulum is present that is divided into two small cusps.
|
| 22. | The longitudinal flagellum lies in a groove-like structure called the cingulum ( F ).
|
| 23. | A weak cingulum is present on the labial side of the tooth between the protoconid and hypoconid.
|
| 24. | The lingual ridge extends from the cingulum to the cusp tip on the lingual surface of most canines.
|
| 25. | One such area of interest is the disruption of white matter in the posterior cingulum causing mild cognitive impairment.
|
| 26. | From a lingual aspect, they have well developed mesial and distal marginal ridges and a well-developed cingulum.
|
| 27. | From a proximal aspect, they resemble the incisors, but are more robust, especially in the cingulum region.
|
| 28. | Neurons of the cingulum receive afferent fibers from the parts of the thalamus that are associated with the spinothalamic tract.
|
| 29. | They are the remnants of three lobes of formation of these teeth, the fourth lobe represented by the cingulum.
|
| 30. | The other two species are smaller in size, and possess several differences in regards to the trigon and cingulum.
