6)The Blood supply of palate .
3. Introduction
The palate Lies in the roof of the
oral cavity.
Has two parts:
Hard (bony part) palate
anteriorly
Soft (mucous tendon muscular)
palate posteriorly.

6. The Hard palate .
Lies in the roof of the oral cavity .
Forms the floor of the nasal cavity .
Its from by the palatine processes of maxillae
and the horizontal palate of the palatine
bones .”Its bony part” the hard palate is
mobile bone .
Bounded.
By the alveolar arches and behind is
the continuous with the soft palate . It forms
floor of the nasal cavities . The hard palate is
covered with the mucous membrane .
7.
8. The soft palate .
Its called the mucous tendon muscular .
The soft palate is attached to the posterior
border of the hard palate anteriorly ,and the
pharyngeal wall laterally . Its free posterior
border of the soft palate in the midline
projection called The uvula So the soft
palate is immobile bone.
The soft palate is continuous at the side with
the lateral wall of the pharynx . The soft
palate is composed the mucous membrane
,palatine Aponeurosis and muscle .
9. The mucous membrane
covers the upper and
lower surface of the soft
palate .
The palatine aponeurosis is
fibrous sheet attached to
the posterior border of the
hard palate.

14. Nerve supply of the palate.
1)The greater and lesser palatine nerves from
the maxillary branched of the trigeminal
nerve enter the palate from the greater and
lesser palatine foramina.
2)The nasopalatine nerve branch of maxillary
nerve enter the hard palate from the incisive
foramen .
3)The glossopharyngeal nerve supplies the soft
palate .
15.
16. The Blood supply of palate .
1)The greater palatine branch of
the maxillary artery .
2)The ascending palatine branch
of the facial artery .
3)The ascending pharyngeal
artery.
