What is the lingula of the mandible?
The lingula of the mandible (also known as Spix spine) is a triangular bony projection or ridge on the medial surface of the ramus of the mandible, immediately superior to the mandibular foramen. It provides attachment for the sphenomandibular ligament 1,2.
What attaches at the lingula of the mandible?
The lingula of the mandible is a prominent bony ridge on the medial side of the mandible. It is next to the mandibular foramen. It gives attachment to the sphenomandibular ligament.
Where would you locate the Lingula?
The lingula was located at 20.6 +/- 3.5 mm from the anterior border of the mandibular ramus and 16.6 +/- 2.9 mm from the mandibular notch. In the majority of the mandibles studied, the lingula was located above the occlusal plane.
What is Lingula of mandibular foramen?
Lingula has been described as a small tongue shaped, sharp bony projection located on the medial aspect of mandibular ramus close to the posterior margin of the mandibular foramen. [1] It is an important landmark as it lies in proximity to the mandibular foramen.
What is a Lingula dental?
The lingula of the mandible is a tongue-shaped bony projection on the medial surface of the mandibular ramus that forms the medial boundary of the mandibular foramen.1 The lingula is a reliable anatomic landmark used to determine the position of the mandibular foramen.2 Due to the close proximity of the lingula to the …
What passes through mandibular foramen?
The inferior alveolar artery travels within the mandibular foramen. As the inferior alveolar artery travels within the mandibular foramen, it will perfuse the mandible.
What does the lingula do?
The lingula is not technically a lobe, but is the left lung equivalent of the right lung’s middle lobe. The hilium is the root of the lung and contains the structures involved in pulmonary circulation, as well as the pulmonary nerves and lymph vessels.
Is lingula upper or lower lobe?
upper lobe
Description. The left lung, unlike the right does not have a middle lobe. However the term lingula is used to denote a projection of the upper lobe of the left lung that serves as the homologue. This area of the left lobe – the lingula, means little tongue (in Latin) and is often referred to as the tongue in the lung.
What is the mandibular canal?
The mandibular canal is an important inner structure of the mandible, or lower jaw. It is a small canal that contains the inferior alveolar artery and vein, as well as the alveolar nerve. In the ramus, it runs obliquely forward and downward, and in the body, it runs horizontally forward.
What are the holes in the mandible called?
Foramina. The mandible has two main holes (foramina), found on both its right and left sides: The mandibular foramen, is above the mandibular angle in the middle of each ramus.
How many mandibular foramen are there?
Variation. There are two distinct anatomies to its rim.
How does the lingula arise?
The main supply to the lingula comes from the lingular trunk, which originates from the anterior aspect of the pulmonary artery within the fissure and splits into two segmental branches. In some patients, an additional lingular artery arises from the truncus anterior (◘ Fig. 16.1b).
What is lingula function?
What nerve runs through mandibular canal?
The lower branch is called the mandibular nerve [39]. The nerve enters the mandible through the mandibular foramen on the medial surface of the ascending mandibular ramus. After passing through the mandibular foramen, the nerve is called the inferior alveolar nerve.

What is the margin of the mandibular foramen?
Lingula of mandible. The margin of the mandibular foramen is irregular; it presents in front a prominent ridge, surmounted by a sharp spine, the lingula of the mandible which gives attachment to the sphenomandibular ligament; at its lower and back part is a notch from which the mylohyoid groove runs obliquely downward and forward,
What is mandibular bone?
Mandible is the largest, strongest, and only movable facial bone, forming the lower jaw. It is also the only bone that doesn’t articulate with its adjacent skull bones with the help of sutures.
