What is a mental protuberance?

Medical Definition of mental protuberance : the bony protuberance at the front of the lower jaw forming the chin.

What is formed by the mental protuberance and the mental tubercles?

The two mental tubercles along with the medial mental protuberance are collectively called the mental trigone.

What attaches to mental protuberance?

The mental tubercle: A paired bony prominence on each side of the mental protuberance. The oblique line: A crest extending from the ramus to the body of mandible. It provides the insertion point for the depressor anguli oris muscle.

Where is the mental tubercle?

mandible
The symphysis of the external surface of the mandible 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.

What is the mental tubercle of mandible?

Hypertrophic mental tubercles are rare bony exostoses that occur in children in a region where a confluence of facial muscles attach to the mandible. The etiology likely involves bone deposition occurring in an area of muscle pull.

Is the mental protuberance the chin?

The lower portion of the face below the lower lip including the prominence of the lower jaw and the line of fusion of the two separate halves of the jawbone (mandible). This line of fusion (called the symphysis menti) encloses a triangular area at tip of the chin (termed the mental protuberance).

Why is genial tubercle important?

The genial tubercle provides attachment for the genioglossus and the geniohyoid muscles.

Which muscles attach to genial tubercle?

They act as the insertion for the geniohyoid muscles (lower genial tubercles) and genioglossus muscles (upper genial tubercles) [3]. The action of these muscles is associated with two important vital functions- speech and deglutition.

What is Ramus of mandible?

The rami are two vertical processes located on either side of the body; they join the body at the angle of the mandible. At the superior aspect of each ramus, the coronoid and condylar processes articulate with the temporal bone to create the temporomandibular joint which permits mobility.

Why did Neanderthals have an occipital bun?

This enlarged visual cortex also correlates with larger eyes among Neanderthals. The occipital bun has also been hypothesized to function in relieving stress on the neck muscles, offsetting the weight of the Neanderthal’s heavier, more robust face.

What is genial tubercle?

Genial tubercles are tiny bony projections located bilaterally around the lingual foramen, on the lingual surface of the mandible giving attachment to geniohyoid inferiorly & genioglossus superiorly.

What is the function of the mental tubercle?

Mental Tubercle. Oblique line is the extension of the anterior border of the ramus, which travels downwards and forwards to the mental tubercle. Symphysis menti expands inferior inside a triangular prominence known as mental protuberance. It creates the point of chin, the base of which is confined on each side via the mental tubercle.

What is the meaning of mental protuberance?

Mental protuberance. The size and shape of the bones making up this structure are responsible for the size and shape of a person’s chin. Synonyms of mental protuberance include mental process and protuberantia mentalis. Mental in this sense derives from Latin mentum (chin), not mens (mind), source of the more common meaning of mental .

What is the mental protuberance of the skull?

Mental protuberance. Side view of the skull. (Mental protuberance visible but not labeled.) The symphysis of the external surface of the mandible 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.

What is the difference between mental tubercles and mental trigone?

Mental tubercle. The mandibular symphysis 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. The two mental tubercles along with the medial mental protuberance are collectively called the mental trigone.
