In anatomy: the Lingula of left lung, one of the segments of the left lung with a tongue-shape; The Sphenoidal lingula, a part of the sphenoid bone; The Lingula of mandible, a ridge on the medial aspect of the body of the mandible, just anterior to the mandibular foramen; the Lingula of cerebellum; Taenia of fourth ventricle
It helps to divide the trachea into two primary bronchi. The right bronchus makes an angle of 25°, while the left one makes an angle of 45°. The carina is a sensitive area. When the patient is made to lie on their left side, secretions from the right bronchial tree flow toward the Carina due to the effect of gravity.
The lingula on the left lung serves as an anatomic parallel to the middle lobe on the right lung, with both areas being predisposed to similar infections and anatomic complications. [ 13 ] [ 14 ] There are two bronchopulmonary segments of the lingula: superior and inferior.
The right lung has three lobes – upper, middle, and lower (or superior, middle, and inferior), and the left lung has two – upper and lower (or superior and inferior), plus a small tongue-shaped portion of the upper lobe known as the lingula. Each lobe is further divided up into segments called bronchopulmonary segments. Each lung has a ...
The left main bronchus is smaller in caliber but longer than the right, being 5 cm long. It enters the root of the left lung opposite the sixth thoracic vertebra. It passes beneath the aortic arch , crosses in front of the esophagus , the thoracic duct , and the descending aorta , and has the left pulmonary artery lying at first above, and then ...
The root of the right lung lies behind the superior vena cava and part of the right atrium, and below the azygos vein.That of the left lung passes beneath the aortic arch and in front of the descending aorta; the phrenic nerve, pericardiacophrenic artery and vein, and the anterior pulmonary plexus, lie in front of each, and the vagus nerve and posterior pulmonary plexus lie behind.
The lingula of the mandible is a prominent bony ridge on the medial side of the mandible. It is next to the mandibular foramen.
The function of the sphenomandibular ligament is to limit distension of the mandible in an inferior direction. It is slack when the temporomandibular joint (TMJ) is in closed position; it is taut when the condyle of the mandible is situated anterior to the temporomandibular ligament. [2]
