mental tubercle वाक्य

In contrast, some Neanderthal individuals show inferior lateral mental tubercles ( small bumps at the side of the chin ).
This ridge divides below and encloses a triangular eminence, the mental protuberance, the base of which is depressed in the center but raised on either side to form the mental tubercle.
Running backward and upward from each mental tubercle is a faint ridge, the oblique line, which is continuous with the anterior border of the ramus; it affords attachment to the depressor labii Inferioris ( Quadratus labii inferioris ) and depressor anguli oris ( Triangularis ); the platysma is attached below it.
