3. Palate
Lies in the roof of the
oral cavity
Has two parts:
– Hard (bony) palate
anteriorly
– Soft (muscular)
palate posteriorly
hard

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
