elevations
Developmental grooves, supplemental grooves, fossae, and sulci are all _____
depressions
____ are the highest elevation of a cusp; first part of the tooth to be laid down
Cusp tips
___ are the highest elevation of the perimeter of the occlusal surface of the teeh
Marginal ridges
____ run traversely or obliquely from the cusp tip to the central groove; inside central ridges of the teeth
Triangular ridges
_____ extend from the cusp tip onto the buccal and lingual surface of each cusp
Central ridges
The _____ groove runs transversely from the central fossa and is the working groove for the distobuccal cusp of the mandibular molar
Developmental groove
