The palate consists of the hard and soft palate. The hard palate forms the roof of the mouth and is made of bone, while the soft palate is a muscular fold that separates the nasal and oral cavities. Several muscles like the tensor veli palatini and levator veli palatini elevate the soft palate. The palate develops from the palatal processes and nasal septum and has important functions like swallowing and speech. Conditions like cleft palate are birth defects of palate formation, while lesions like nasopalatine duct cysts can occur. The detailed document discusses the anatomy, development, clinical considerations and related structures of the palate.
The pharynx is a hollow tube that starts behind the nose, goes down the neck, and ends at the top of the trachea and esophagus. The three parts of the pharynx are the nasopharynx, oropharynx, and hypopharynx.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

• Development Of palate
• Clinical Consideration
3. Introduction
• Palate – Roof of the oral cavity
• It has two parts
1- An anterior hard palate
2- A posterior soft palate
4. Hard Palate
• Separates the oral cavity from the nasal
cavities
• Consists of a bony plate covered above and
below by mucosa
• Above- covered by respiratory mucosa and
forms floor of nasal cavity (superior surface)
• Below- covered by oral mucosa and forms
much of the roof of oral cavity(inferior
surface)
5. Formed by
• Palatine processes of maxillae in front
• Horizontal plates of palatine bones behind
• Bounded by alveolar arches
• Posteriorly continues with soft palate
• Its under surface covered by mucoperiosteum
• Show transverse ridges in the anterior parts
6. Position
• The anterolateral margins of the palate are
continuous with the alveolar arch and gums
• The posterior margins 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
7. Osteology
• Palatine processes of the maxillae form anterior ¾ of the
hard palate
• Horizontal plate of the palatine bones form the posterior ¼
of the hard palate
10. Soft palate
Movable ,muscular fold ,suspended from the
posterior border of the hard palate
It separates the nasopharynx from the
oropharynx
Acts as a valve that can be
1.-depressed to help close the oropharyngeal
isthmus.
2.-elevates to separate the nasopharynx from the
oropharynx.
11. • Has two surfaces
• 1 Anterior (oral) surface; is concave and is marked by median
raphe.
• 2 Posterior surface is convex and is continuous superiorly with
the floor of the nasal cavity
12. • Has two borders
• 1 superior border is attached to the posterior border of the hard
palate ,blending on each side border of the hard palate ,with the
pharynx.
• 2 .Inferior border is free and bounds the pharyngeal isthmus.
• From its middle there hangs a conical projection,called uvula .
13. • Has two folds
• From each side of the ovulae ,two curved folds of mucous
membrane extend laterally and downwards
• The anterior fold is called as palatopharyngeus arch (ant pillar
of faucets) it contains palatoglossuss muscle and reaches the
side of the tongue at the junction of its oral and pharyngeal
parts.
• The posterior fold is called the palatopharyngeal arch (post
pillar of fauces) contains palatopharyngeus muscle .
• And it forms the posterior boundary of the tonsillar fossa,
and merges inferiorly with lateral wall of the pharynx.
14. Muscle of palate
• Tensor veli palatini
• Levator veli palatini
• Musculus uvulae
• Palato pharyngeus
• Palato glossus
15. TENSOR VELI PALATINI
Origin
Lateral side of auditory tube
Scaphoid fossa of sphenoid bone
Insertion
Palatine aponeurosis
Nerve Supply
Mandibular nerve branch to medial
pterygoid muscle
Action
Tightens the soft palate
Open the auditory tube
16. LEVATOR VELI PALATINI
Origin
Petrous temporal bone
Inferior aspect of auditory tube
Insertion
Upper surface of palatine aponeurosis
Nerve Supply
Vagus nerve via pharyengeal plexus
Action
Elevated the soft palate
17. MUSCULUS UVULAE
Origin
Posterior nasal spine of hard palate
Insertion
Connection of uvula
Nerve Supply
Vagus nerve via pharyngeal plexus
Action
Elevates and reacts uvula
Thickens central region of soft palate
18. PALATOGLOSSUS
Origin
Inferior surface of palatine aponeurosis
Insertion
Lateral margin of tongue
Nerve Supply
Vagus nerve via pharyngeal plexus
Action
Depress palate
Moves palatoglossal arch toward midline
Elevates back of the tongue
22. PASSAVNT’S RIDGE
• Some of the upper fibres of the palatopharyngeal passes circularly deep
to mucous membrane of the pharynx
• Forms a sphincter internal to the superior constrictor
• This constitute the Passavant’s muscle
• On contraction raises a ridge called Passavant’s ridge
• Best developed in the cleft palate cases
23. Movement and function
• Plays important role in
• Swallowing
• Chewing
• Voice
• Sneezing
• Coughing
• Act as a traffic controller between oropharynx and
nasopharynx
31. Development Of The Primary Palate
Fusion of the two medial nasal processes with
frontonasal process result in the formation of primary
palate
32. Development Of The Secondary Palate
• The formation of secondary palate commence between 7 and 8
week and complete around the 3rd month of the gestation
• Three outgrowth appear in the oral cavity
-The two palatal process
-The nasal septum
33. • Each palatal process grow downward
first then upward after the withdrawal of
tongue (7th week)
• Septum and the two shelves converge
and fuse in the midline
• The closure of the secondary palate
proceed gradually form the primary
palate in a posterior direction.
35. Classification of soft palate by M M House
• Class1 –Soft tissue is almost horizontal
• Class2 – Soft palate turns downward at an angle
of 450 from hard palate
• Class 3 – Soft palate turns downward sharply at
an angle of 75o from hard palate
36. Roughly correspondes to Cormack
and Lehane’s Laryngoscopy views
• Class I- visualization of the soft palate ,fauces
,uvula and both anterior and posterior pillars
• Class II –Visualization of the soft palate,
Fauces and uvula
• ClassIII –Visualization of the soft palate and
the base of uvula
• Class IV – Difficult visualization of soft palate
37. Uranoschisis -CLEFT PALATE
• Congenital birth defect
• Defective fusion of the maxillary process / Palatal
process of palate gives rise to cleft in palate
• Etiology
Defective growth of palatal shelves
Lack of contact between shelves
Post fusion rupture of shelves
Delayed /failure of shelves to attain a horizontal
position
38. Classification of cleft palate
• Veaus Classification
• Class 1 incomplete cleft involving only
soft palate
• Class2 cleft involving hard and soft
palate
• Class3 complete unilateral cleft
involving lip and palate
• Class4 complete bilateral cleft
39.
40. Dental problems
• Congenital missing teeth
mostly upper lateral incisors
• Presence of supernumerary,
neonatal and natal teeth
• Ectopically erupted tooth
• Enamel hypoplasia
• Microdontia ,macrodontia
• Fused teeth
• Gemination ,dilaceration
• Tendency toward class III
skeletal pattern
• Posterior and anterior cross bite
• Deep Bite
• Spacing / Crowding
• Protruding premaxilla
41. TORUS PALATINUS
• Localised nodular enlargement of the
cortical bone
• Usually midline of the palate
• Pose a mechanical problem in the
construction of denture
43. SMOKER’S PALATE
• Also known as nicotine stomatitis
• An erythematous irritation is
initially seen ,followed by a whitish
palatal mucosa reflecting a
hyperkeratosis
• Red dots representing orifices of
accessory salivary glands seen
44. HIGH ARCHED PALATE
• Developmental feature that may occur in
isolation or in association with a number of
conditions
• Acquired condition caused by chronic thumb
sucking
• High arched palate may cause narrowed
airway and sleep disordered breathing
• Pose difficulty in the construction of denture
Normal arch palate
High arch palate
45. Incisive canal cysts
• Incisive canal cysts, also known as nasopalatine duct
cysts (NPDC), are developmental, non-neoplastic cysts arising from
degeneration of nasopalatine ducts.
• These ducts usually regress in fetal life. The persistence of ductal
epithelium leads to formation of cyst.
• It is considered the most common non-odontogenic cyst and develops
only in the midline anterior maxilla.
• It represents as asymptomatic palatal swelling
46. • They are seen as a solitary well-
defined, oval or round unilocular
radiolucency, between central
incisors, >0.6 cm in diameter. They
may appear “heart-shaped” if the
anterior nasal spine superimposed.
Root resorption and tooth
displacement may be present.
47. Paralysis of soft palate
• The pharyngeal isthmus can not be closed during swallowing and
speech
• Nasal regurgitation
• Nasal Twang
• Flattening of palatoglossal arch
