HARD PALATE: position
• The anteriolateral margins of the palate are continuous with the alveolar arches and gums.
• The posterior margin gives attachment to the soft palate.
• The superior surface forms the floor of the nose.
• The inferior surface forms the roof of the oral cavity

HARD PALATE: vessels and nerves
• Arteries: Greater palatine branch of maxillary artery.
• Veins: pterygoid plexus of veins.• Nerves: Greater palatine and nasopalatine
branches of the pterygopalatine ganglion suspended by the maxillary nerve.
• Lymphatics: The lymphatics drain mostly to the upper deep cervical nodes and partialy to the retropharyngeal nodes.

SOFT PALATE: SURFACES
• 1. The anterior (oral) surface- is concave and is marked by median raphe.
• 2. The posterior surface- is convex , and is continuous superiorly with the floor of the nasal cavity.

SOFT PALATE: Borders
• 1. The superior border –is attached to the posterior border of the hardpalate ,blending on each side with the pharynx.
• 2. The inferior border- is free and bounds the pharyngeal isthmus. From its middle, there hangs a conical projection , called uvula.
