What are mental spines?
Medical Definition of mental spine : either of two small elevations on the inner surface of each side of the symphysis of the lower jaw of which the superior one on each side provides attachment for the genioglossus and the inferior for the geniohyoid muscle.
What are genial tubercles?
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 muscles attach to the mental spine?
The mental spine is the point of insertion of the geniohyoid muscle, one of the suprahyoid muscles and the origin of the genioglossus muscle, one of the muscles of the tongue.
What attaches to inferior mental spine?
The mental spine provides muscle attachments to the genioglossus muscle, which attaches to the superior pair, and to the geniohyoid muscle, which attaches to the inferior pair.

What muscles attach to the genial tubercles?
Genial tubercle – The genial tubercle is a spiny protuberance or prominence (sometimes two) of bone located in the midline on the lingual aspect of the mandible below the roots of the incisor teeth. This structure serves as the locus of attachment for the genioglossus and geniohyoid muscles.
How many genial tubercle are there?
How does genial tubercle appear on a radiograph?
In these periapical radiographs of the mandibular anterior region, the genial tubercles appear as a distinct radiopacity, a band of dense bone, near the midline below the apices of the teeth. The lingual foramen also appears in these radiographs, as a small cirradiolucent area surrounded by the genial tubercles.
Where are the genial tubercles located quizlet?
the genial tubercles (mental spine) are found on the lingual midline, just above the inferior border of the mandible.
What is geniohyoid?
The geniohyoid muscle is one of the suprahyoid muscles of the neck that is innervated by the ventral ramus of C1. Geniohyoid draws the hyoid bone up and forward during mastication and assists the opening of the mandible.
Are genial tubercles radiopaque?
Radiographically, the genial tubercles appear as a circular radiopacity located beneath the apices of the lower incisors, which can be observed on conventional periapical, occlusal and panoramic radiographs1, as well as by three-dimensional imaging methods such as cone-beam computed tomography (CBCT).
What are the genial tubercles located?
The genial tubercles (GTs) are an important anatomical landmark that is located in the midline of the lingual side of the mandible and is important for multiple clinical and surgical interventions.
