Lesser palatine nerve

Lesser palatine nerve is a branch of the Pterygopalatine ganglion that supplies the soft palate and tonsils. It is also known as the small palatine nerve or anterior palatine nerve.

Etymology

The term "palatine" is derived from the Latin word "palatum" which means "roof of the mouth". The term "lesser" is used to differentiate this nerve from the larger, greater palatine nerve.

Anatomy

The lesser palatine nerve originates from the pterygopalatine ganglion, which is itself a branch of the maxillary nerve. It descends through the lesser palatine canal to reach the soft palate and tonsils.

Function

The lesser palatine nerve provides sensory innervation to the soft palate and tonsils. This means it carries sensory information from these areas to the brain.

Clinical significance

Damage to the lesser palatine nerve can result in loss of sensation in the soft palate and tonsils. This can affect speech and swallowing.
