Quizplus · Accepted Answer

The triangular ridge is an elevation of enamel that descends from the cusp into the middle area of the occlusal surface. The transverse ridge connects two cusps and is not descending into the middle area. The oblique ridge crosses the occlusal surface diagonally and is not primarily descending into the middle area. The marginal ridge is a raised border located on the mesial and distal portions of the occlusal surface that does not typically descend into the center area.
