The palate has two parts: the hard (bony) palate anteriorly and the soft (muscular) palate posteriorly. The hard palate forms the roof of the oral cavity and floor of the nose. It receives blood vessels from the greater palatine artery and nerves from the greater palatine and nasopalatine nerves. The soft palate is a movable muscular fold suspended from the posterior border of the hard palate. It has anterior and posterior surfaces and superior and inferior borders, and hangs the conical uvula from its middle.

8. 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

9. 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.

10. SOFT PALATE
• It is movable, muscular fold, suspended from
the posterior border of the hard palate.

12. 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.

14. 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.

18. Palatine Aponeurosis
Fibrous sheath
Attached to posterior
border of hard palate
Is expanded tendon of
tensor velli palatini
Splits to enclose
musculus uvulae
Gives origin & insertion
to palatine muscles
