What is lingula in mandible?
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 …
Where is the lingula of 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 bone has a lingula a condyle and a mental foramen?
the mandible
The inferior alveolar nerve runs through the mandible from the lingula to the mental foramen and is at risk of damage both as the result of the injury and during fixation of the fracture.
What is squamous cell carcinoma of the mandible?
Squamous cell carcinoma is the most common head and neck malignancy. It can occur in the mandible or maxilla without a preexisting oral mucosal lesion. Often, the clinical and radiographic presentation of SCC directs the clinician to favour malignancy over other pathological conditions.
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.
What passes through the mandibular foramen?
The mandibular foramen contains a branch of the trigeminal nerve (CN V), a branch of the maxillary artery and the inferior alveolar vein. The nerve and blood vessels within the mandibular foramen are the inferior alveolar nerve, artery, and vein.
Where is the left lingula?
left lung
Anatomical Parts 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 purpose of the mandible bone?
The mandible is the largest bone in the human skull. It holds the lower teeth in place, it assists in mastication and forms the lower jawline.
What is behind the mandible?
The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints.
What is mandibular carcinoma?
Mandibular cancer arises from the gums and lower jaw. Sometimes, these cancers start in the jaw bone itself, and sometimes they start in the gums, or in other places, such as the lips, cheek, or tongue, and grow into the bone.
What is the prognosis for squamous cell carcinoma?
Squamous cell carcinoma (SCC) generally has a high survival rate. The 5-year survival is 99 percent when detected early. Once SCC has spread to the lymph nodes and beyond, the survival rates are lower. Yet this cancer is still treatable with surgery and other therapies, even in its advanced stages.
What does lingula mean?
Medical Definition of lingula : a tongue-shaped process or part: as. a : a ridge of bone in the angle between the body and the greater wing of the sphenoid. b : an elongated prominence of the superior vermis of the cerebellum.
Where is the lingula located on the mandible?
Lingula (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 is the treatment for a mandibular cancer?
The treatment for mandibular cancers is usually surgery, sometimes followed by radiation treatment and occasionally chemotherapy.
Where does mandibular cancer start in the body?
Mandibular cancer arises from the gums and lower jaw. Sometimes, these cancers start in the jaw bone itself, and sometimes they start in the gums, or in other places, such as the lips, cheek, or tongue, and grow into the bone. Excessive tobacco and alcohol use are both known to contribute to the development of this type of cancer.
What is the function of the lingula in the spinal cord?
The Lingula is also a part of the cerebellar vermis and keeps you standing upright by taking sensory inputs coming up the spinal cord and modifying the motor commands being sent down. It thus plays a part in maintaining balance, facilitating and smoothing movement and controlling posture.
