mental tubercle造句

• 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.
