Foramina of the hard palate
Incisive fossa
Greater palatine foramen
Lesser palatine foramina
Located of the incisive fossa

Nasopalatine nerves
Pass from the nose to supply the ant part of the hard palate
Location of the greater palatine foramen
Medial to the 3rd molar tooth
What passes through the greater palatine foramen
Greater palatine vessels and nerve
Emerge from the foramen and run anteriorly on the palate
What runs through the lesser palatine foramina
The lesser palatine nerves and vessels
Transmits to the soft palate and adjacent structures
Movable third of the palate
Soft palate
The soft palate extends ______ as a curved free margin from which hangs:
Posteroinferiorly
A conical process, the uvula
The palatine aponeurosis is formed by the expanded tendon of the ____ ___ ____.
It is attached to the:
Tensor veil palatini
Post arginine of the hard palate
The soft palate is continuous with the:
Wall of the pharynx by the palatopharyngeal arch
The soft palate is joined to the tongue by the:
Palatoglossal arch
Location of the palatine tonsils
One on each side of the oropharynx between the palatoglossal and palatopharyngeal arches
Muscles of the soft palate
Tensor veil palatini
Levatorveli palatini
Palatoglossal
Palatopharyngeus
Musculus uvulae
OINA for tensor veil palatini
OR: scaphoid fossa at post border of medial pterygoid plate
INS: palatine aponeurosis
NS: nerve to medial pterygoid (branch of CN V3)
AC:: tenses soft palate and opens mouth of pharyngotympanic tube during swallowing and yawning
OINA for levatorveli palatini
OR: cartilage of pharyngotympanic tube and petrous part of temporal bone
INS: palatine aponeurosis
NS: Pharyngeal plexus
AC: elevates soft palate during swallowing and yawning
OINA for palatoglossus
OR: palatine aponeurosis
INS: side of tongue
NS: Pharyngeal plexus
AC: Elevates post part of the tongue and draws soft palate onto tongue
OINA for palatopharyngeus
OR: Palatine aponeurosis
INS: Lateral wall of pharynx
NS: pharyngeal plexus
AC: tenses soft palate and pulls walls of pharynx superiorly, during swallowing
OINA for Musculus uvulae
OR: post nasal spine and palatine aponeurosis
INS: Mucosa of uvula
NS: pharyngeal plexus
AC: shortens uvula and pulls superiorly
Vasculature of palate

Divides into:
Greater palatine
And lesser palatine
The greater palatine arteries enter the palate through the ____ ____ foramen and passes anteriorly to supply:

The major portion of the hard palate
The lesser palatine artery enters the palate through the ___ ___ foramen
Anastomoses with the ____ ____ artery (a branch of the ____ art)
Lesser palatine
Ascending palatine
Facial
Innervation of the palate
Greater palatine nerve
Nasopalatine nerve
Lesser palatine nerves
Pharyngeal plexus
What does the greater palatine nerve supply
The gingivae
Mucous membrane
Glands of most of the hard palate
What does the nasopalatine nerve supply
The mucous membrane of the anterior part of the hard palate
What do the lesser palatine nerves supply
The soft palate
The pharyngeal plexus is formed by the _______ branch of:
Pharyngeal
Vagus (motor) and glossopharyngeal (sensory)
What does the pharyngeal plexus supply
All muscles of the soft palate except the tensor veil palatini supplies by mandibular nerve (CN V3)
