What does inferior alveolar innervate?
The Inferior Alveolar nerves supply sensation to the lower teeth, and, via the mental nerve, sensation to the chin and lower lip. The mylohyoid nerve is a motor nerve supplying the mylohyoid and the anterior belly of the digastric.
Is inferior alveolar nerve sensory or motor?
Inferior alveolar nerve—this is a dual motor and sensory nerve. It passes on the medial aspect of the lateral pterygoid and just before entering the mandibular foramen, it gives rise to the motor branches to the mylohyoid and anterior belly of digastric muscles.
Is the lingual nerve a branch of the inferior alveolar nerve?
The lingual nerve lies at first beneath the lateral pterygoid muscle, medial to and in front of the inferior alveolar nerve, and is occasionally joined to this nerve by a branch which may cross the internal maxillary artery.
What causes inferior alveolar nerve?
Introduction. Causes of inferior alveolar nerve (IAN) injury include local anesthetic injections, third molar surgery (TMS), implants, endodontics, ablative surgery, trauma, and orthognathic surgery.
Where is the inferior alveolar?
mandible
The inferior alveolar nerve is situated near the lower jawbone, known as the mandible. It crosses to the mandibular foramen (the upper side portion of the mandible) and provides a nerve extension to the mylohyoid muscle that makes up the bottom of the oral cavity.
What is nervus Spinosus?
The nervus spinous (plural: nervi spinosi), also known as the meningeal branch of the mandibular nerve, is a branch of the mandibular division of the trigeminal nerve which innervates the dura of the middle cranial fossa.
Where is the lingual nerve in the tongue?
The lingual nerve is a sensory branch of the posterior division of the mandibular division of the trigeminal nerve supplying sensation (both gustatory (taste) and non-gustatory) to the anterior two-thirds of the tongue.
