Palatine nerves

Palatine nerves are a group of nerves originating from the maxillary nerve, a branch of the trigeminal nerve, which is the fifth cranial nerve. They are responsible for providing sensory innervation to the hard palate and soft palate, the regions of the mouth that form the roof of the oral cavity.

Anatomy

The palatine nerves are divided into two main branches: the greater and lesser palatine nerves.

Greater Palatine Nerve

The Greater Palatine Nerve descends through the greater palatine canal, exiting via the greater palatine foramen. It provides sensory innervation to the hard palate, the gums, and the mucous membrane and glands of the hard palate.

Greater and lesser palatine nerves.

Lesser Palatine Nerve

The Lesser Palatine Nerve exits through the lesser palatine foramina and innervates the soft palate, tonsils, and uvula. It also carries some taste fibers from the soft palate.

Clinical Significance

Understanding the anatomy and function of the palatine nerves is crucial in various medical and dental procedures, such as palatine nerve block and palatal biopsy. Damage to these nerves can result in loss of sensation or altered sensation in the palate, which can affect speech and swallowing.
