Anaesthetic injected near the mandibular foramen to block the inferior alveolar nerve and the nearby lingual nerve (supplying the tongue). This causes loss of sensation on the same side as the block to: the teeth (inferior alveolar nerve block) the lower lip and chin (mental nerve block) front two-thirds of the tongue (lingual nerve block).
The inferior alveolar nerve passes lateral to the raphe; the raphe is therefore a landmark for a nerve block of this nerve. [2] ... "Anatomy diagram: 05287.011-1".
The mental nerve is a branch of the posterior trunk of the inferior alveolar nerve. This is a branch of the mandibular nerve (CN V 3), itself a branch of the trigeminal nerve (CN V). [1] It emerges from the mental foramen in the mandible. [2] It divides into three branches beneath the depressor anguli oris muscle.

In human anatomy, the mandibular canal is a canal within the mandible that contains the inferior alveolar nerve, inferior alveolar artery, and inferior alveolar vein. It runs obliquely downward and forward in the ramus, and then horizontally forward in the body, where it is placed under the alveoli and communicates with them by small openings.
Another possible complication of an inferior alveolar nerve block occurs when the needle is placed too deep, passing through the pterygomandibular space and into the parotid gland behind. Branches of the facial nerve (which gives the motor supply to the muscles of facial expression ) run through the substance of the parotid gland and so this is ...
The mental foramen descends slightly in toothless individuals. [2]The mental foramen is in line with the longitudinal axis of the 2nd premolar in 63% of people. [3] It generally lies at the level of the vestibular fornix and about a finger's breadth above the inferior border of the mandible.
The alveolar nerves or dental nerves include three superior alveolar nerves: the anterior superior alveolar nerve, middle superior alveolar nerve, and posterior superior alveolar nerve, and an inferior alveolar nerve. [1] The superior alveolar nerves are all branches of the maxillary nerve, which is the second branch of the trigeminal nerve.
