Structure

The lesser palatine canals start from the greater palatine canal, and run with them, also opening into the roof of the oral cavity. Their openings are known as the lesser palatine foramina, and they transmit the lesser palatine artery, vein, and nerve, as well as the middle palatine vessels and nerve.^[1]
