The nose develops from the frontonasal process and surrounding structures in the embryo. It has bony and cartilaginous components that provide structure. The nasal cavities contain three turbinates and three meatuses for drainage. The paranasal sinuses develop later in life and include the maxillary, ethmoid, frontal, and sphenoid sinuses. The sinuses are lined with mucous membrane and have ostia that drain into the meatuses. The nose has important functions including warming, humidifying, and filtering air as well as roles in smell and voice resonance.
This document discusses the anatomy and development of the nose and paranasal sinuses. It begins with the embryonic development of the nose from 4-7 weeks of gestation. It then describes the development of the paranasal sinuses from 25-28 weeks of gestation onward. Next, it covers the anatomy of the external nose, nasal cavity, paranasal sinuses and related structures.

This document provides an overview of the nose and paranasal sinuses. It begins by defining some key anatomical landmarks of the nose, including the nasion, rhinion, dorsum, and columella. It then describes the external nose and nasal cavity in more detail. The four paranasal sinuses - frontal, maxillary, sphenoidal, and ethmoidal - are also summarized. The document concludes with brief descriptions of the pterygopalatine fossa, ganglion, and some clinical considerations.
The lateral wall of the nasal cavity is formed by several bones including the nasal, maxilla, lacrimal, ethmoid, palatine and sphenoid bones. It contains three bony projections called turbinates. Several anatomical structures are located within the lateral wall including the agger nasi cell, ethmoid bulla, uncinate process and ostiomeatal complex. The document describes the bones, turbinates, sinuses and various anatomical variations that can be present within the lateral wall of the nasal cavity.
The paranasal sinuses are air spaces that develop within the bones of the skull. There are four pairs - maxillary, frontal, ethmoid, and sphenoid. They are rudimentary at birth and enlarge throughout childhood. The maxillary sinus is the largest and the first to develop. Acute sinusitis is usually caused by bacterial infections spreading from the nose. Chronic sinusitis lasts for months or years. Complications can include infections of nearby structures like the orbit or brain. Neoplasms of the sinuses can also occur but are usually benign growths like osteomas.
The nasal cavity and paranasal sinuses are described. The nasal cavity is divided into two nasal fossae by the nasal septum. Each fossa is bounded by bones including the maxilla, ethmoid, frontal, sphenoid and palatine. There are four paranasal sinuses on each side - the maxillary, ethmoid, frontal and sphenoid sinuses. The maxillary sinus is the largest sinus and is located within the body of the maxilla. The ethmoid sinuses are located within the ethmoid bone and are divided into anterior and posterior groups. The frontal sinus is an extension of the anterior ethmoid cells located within the frontal bone.
The document describes the histological features of the nasal mucosa and paranasal sinuses. It discusses the three parts of the nasal cavity - the vestibular, respiratory, and olfactory mucosa. The respiratory mucosa lines the respiratory part of the nose and paranasal sinuses. It consists of pseudostratified ciliated columnar epithelium with goblet cells and contains serous and mucous glands. The olfactory mucosa contains bipolar olfactory neurons, supporting cells, and basal stem cells. It is located in the upper part of the nose and detects smells. The paranasal sinuses are air filled cavities connected to the nose and are also lined with respiratory mucosa.
A presentation about the Human Nasal Cavity. This slides were made for an oral report in partial fulfillment of the requirements in PH 121: Anatomy Lecture but was never presented due to time constraints.May you find it useful.
The nose has two parts - the external nose and internal nose. The external nose is made of bone and cartilage and covered in skin, muscles, and glands. The internal nose is divided by the nasal septum into left and right nasal cavities. Each cavity contains the vestibule in front lined by skin and the nasal cavity proper lined by mucosa. The nasal cavity contains turbinates which increase the surface area for airflow and drainage of paranasal sinuses. Nerves supply sensation and control blood flow and secretions to support the nose's roles in breathing, smell, and drainage.
The nose has an external triangular pyramid shape directed downward with two nostrils separated by a septum. Internally, the nasal cavity is lined by ciliated epithelium and contains three turbinates and paranasal sinuses. The nasal septum separates the two nasal cavities and has attachments to the maxilla, frontal bone, and perpendicular plate of the ethmoid. Arterial blood supply comes from the maxillary and sphenopalatine arteries while nerve supply is from the trigeminal and vidian nerves. The paranasal sinuses include the maxillary, frontal, ethmoid, and sphenoid sinuses.
The nasal cavity and sphenoid sinus are described. The nasal cavity is divided into two halves by the nasal septum and has three regions: the vestibule, respiratory region, and olfactory region. It is bounded by bones and cartilages. The sphenoid sinus is located in the sphenoid bone and has relationships superiorly to the cranial cavity and pituitary gland. It varies in size and can extend into surrounding bones. Both structures receive blood supply from ethmoidal arteries and nerve supply from ethmoidal nerves.
This document outlines the sessions and content of a continuing dental education program on the anatomy, physiology, and disorders of the nose, paranasal sinuses, and face. The program consists of four sessions that each last 100 minutes and cover topics such as the basic anatomy and physiology of the nose, clinical examination of the nose, and common tumors and disorders that can affect the nose and face. The sessions include lectures, discussions, and question periods. Diagnostic imaging modalities for examining the nose and sinuses such as CT, MRI, and ultrasound are also discussed. Common benign and malignant tumors seen in the nose like inverted papillomas and osteomas are described.
The nose and paranasal sinuses develop from neural crest cells and mesoderm that proliferate to form the nasal placodes and prominences. This results in the formation of the nasal cavity and associated structures.
The nose has an external pyramidal portion made of bone and cartilage and an internal nasal cavity lined by different types of mucosa and divided by the nasal septum. The nasal cavity connects to the paranasal sinuses and drains into the nasopharynx. The maxillary sinus is the largest paranasal sinus located within the maxilla.
The paranasal sinuses are air-filled spaces in the skull bones surrounding the nose. There are four main paranasal sinuses: the frontal sinuses, ethmoidal sinuses, maxillary sinus, and sphenoid sinus. The paranasal sinuses lighten the skull, increase voice resonance, and act as cushions protecting the brain, eyes, and pituitary gland. The sinuses develop after birth and increase in size with the eruption of permanent teeth.
This document discusses the physiology and functions of the nose and paranasal sinuses. It covers the following key points:
- The nose acts as the primary airway for breathing and helps warm, humidify, and filter inspired air. It also plays roles in vocal resonance, drainage, and olfaction.
- The paranasal sinuses provide air conditioning functions, help reduce skull weight, and drain secretions through ostia into the nasal cavities and pharynx.
- Cilia and mucus in the nose help clear foreign particles via the mucociliary escalator. Various reflexes also help protect the nasal and lung functions.
The patient likely experienced bubbling of blood and escape of fluids through his nostril following extraction of his second upper molar because the maxillary sinus had pneumatized (enlarged) into the alveolar bone that formerly supported the extracted tooth root. When the tooth was extracted, it created a communication between the maxillary sinus and oral cavity, allowing sinus contents like blood and mucus to drain out through the nasal cavity.

Use of modified tooth forms in complete denture occlusion / dental implant...Indian dental academy
This document discusses dental occlusion concepts and philosophies for complete dentures. It introduces key terms like physiologic occlusion and defines different occlusion schemes like balanced articulation and monoplane articulation. The document discusses advantages and disadvantages of using anatomic versus non-anatomic teeth for complete dentures. It also outlines requirements for maintaining denture stability, such as balanced occlusal contacts and control of horizontal forces. The goal of occlusion for complete dentures is to re-establish the homeostasis of the masticatory system disrupted by edentulism.

How to Build a Module in Odoo 17 Using the Scaffold MethodCeline George
Odoo provides an option for creating a module by using a single line command. By using this command the user can make a whole structure of a module. It is very easy for a beginner to make a module. There is no need to make each file manually. This slide will show how to create a module using the scaffold method.
How to Fix the Import Error in the Odoo 17Celine George
An import error occurs when a program fails to import a module or library, disrupting its execution. In languages like Python, this issue arises when the specified module cannot be found or accessed, hindering the program's functionality. Resolving import errors is crucial for maintaining smooth software operation and uninterrupted development processes.

it describes the bony anatomy including the femoral head , acetabulum, labrum . also discusses the capsule , ligaments . muscle that act on the hip joint and the range of motion are outlined. factors affecting hip joint stability and weight transmission through the joint are summarized.
2. INTRODUCTION
• Nose performs two functions:
- Respiratory passage
-Organ of smell
• Receptors of smell are placed in the upper one
third of the nasal cavity and this is lined by
respiratory mucosa.
• This Mucosa is highly vascular and warms the
Inspired air.
• The secretions of the serous glands make the air
moist and secretions of the mucous glands trap
dust and other particles.
www.indiandentalacademy.com
3. NASAL CAVITY
• It extends from the Nostrils to the posterior Nasal
apertures.
• It is divided into right and left half by Nasal septum.
• Each half has- Roof, Floor, Lateral & Medial walls
• The Middle horizontal part is formed by the Cribriform plate
of the Ethmoid.
• The anterior slope is formed by the Nasal part of Frontal
bone, Nasal bone &Nasal cartilages.
• The Floor is formed by the Palatine process of Maxilla
&Horizontal plate of Palatine bone
www.indiandentalacademy.com
5. NASAL SEPTUM
• It is a Osteo cartilagineous partition b/w the two
halves, which form the medial wall of both
cavities.
• Bony part is formed by:
- Vomer
- Perpendicular plate of Ethmoid
• Cartilagenous part is formed by:
-Septal cartilage
-Septal process of Inf nasal cartls
www.indiandentalacademy.com
8. • Cuticular part (lower end) is formed
by Fibro fatty tissue, covered by
skin.
• Lower margin of the septum is called
as Columella.
• Nasal septum is strictly median,if at
all is deflected, is produced by the
over growth of one or more
constituent parts.

9. BLOOD SUPPLY
• Ant sup part :- Ant Ethmoidal artery
-Sup Lab branch of Facial
artery
• Postero Inf part:- Sphenlpalatine artery
• Ant Inf part( vestibule):-Anast b/w Lab branch of
Facial artery and Sphenopalatine artery.
• This is common site of Bleeding from Nose
(EPISTAXIS), known as Littles area/
Kiesselbach’s area
www.indiandentalacademy.com
13. VENOUS DRAINAGE
• The veins form a Plexus in the lower part
of the septum- LITTLES AREA
• The plexus drains anteriorly into facial
vein and post by Sphenopalatine vein to
Pterygoid venous plexus.
• Lymphatic drainage:
Ant half: by submandibular nodes.
Post half: to the retro pharyngeal &
deep cervical nodes.www.indiandentalacademy.com
15. NERVE SUPPLY
• General sensory nerves: Trigeminal
nerve.
A) Ant sup part :- Int nasal branch of Ant
Ethmoidal nerve
B)Post Inf part :-Nasopalatine branch of
Pterygopalatine ganglion.
• Special sensory nerves (Olfactory) are
confined to upper part (Olfactory area)www.indiandentalacademy.com
17. LATERAL WALL OF NOSE
• It contains 3 bony projections called
CONCHAE, these increase the surface
area for effective conditioning of the air.
• Lateral wall separates the Nose from:
A) Orbit above by Ethmoidal air
sinus
B) Max sinus below
C) Lacrimal groove &Naso lacrimal
canal in front
www.indiandentalacademy.com
18. • It can be subdivided into 3 parts:-
A) small depressed area in the
ant area called Vestibule, lined by
modified skin containing short stiff
curved hairs called Vibrissae.
B) Middle part is known as the
Atrium of the middle meatus.
C)Post part contains Conchae,
spaces separating Conchae are
called Meatus.www.indiandentalacademy.com
19. • Skeleton of Lateral wall:- partly bony &
partly Cartilagenous.
• Bony part:- Nasal, Frontal process of Max,
Lacrimal, Labrinth of Ethmoid with sup and
middle conchae, Inf nasal concha,
Perpendicular plate of Palatine bone
together with Orbital and Sphenoidal
process, and medial pterygoid plate.
• Cartilaginous part:- Upper & Lower nasal
cartilage, 3 or 4 small cartilages of ala.
www.indiandentalacademy.com
22. • Cuticular part:- is formed by the fibro fatty
tissue covered with skin. It contains:-
A)Nasal concha- 3 in nos
1)Inf concha-is an independent bone
2)Middle concha- projections from the
medial surface of the Ethmoidal labyrinth
3)Sup concha- also a projection from
Ethmoidal labyrinth
www.indiandentalacademy.com
24. • B) Meatus of the Nose:- They are the passages
beneath the over hanging concha.
1)Inf meatus- it is the largest and lies underneath
the Inf conchae. Naso-lacrimal duct opens into it,
the opening is guarded by the Hasners valve/
Lacrimal fold.
2)Middle meatus- lies underneath the middle
concha, contains:
-Ethmoidal bulla
-Hiatus Semilunaris
-Infundibulum
-Opening of Frontal air sinus
-Opening of Max air sinus
-Opening of Middle Ethmoidal sinuswww.indiandentalacademy.com
28. ATRERIAL SUPPLY
• Ant Sup quadrant:- Ant Ethmoidal artery,
assisted by Post Ethmoidal and Facial
arteries.
• Ant Inf quadrant:-Branches of Facial and
Gr palatine artery
• Post Sup quadrant:-Sphenopalatine artery
• Post Inf quadrant:-Branches of Gr Palatine
artery
• Venous drainage:- Form a Plexus which
drains Ant into Facial vein, Post into
Pharyngeal Plaexus of veins, and middle
into Pterygoid Plexus of veins.www.indiandentalacademy.com
34. • Special sensory nerve (Olfactory):-
They are distributed to the upper part of the
Lat wall just below the Cribriform plate of
the Ethmoid upto the Sup Conchae.
Note:- All Olfactory mucosa lies partly on nasal septum
and Lateral wall.
• Lymphatic drainage:- Ant half passes
to the Submandibular nodes, Post half -
Retro Pharyngeal, and upper deep cervical
nodes. www.indiandentalacademy.com
36. APPLIED ANATOMY
• TRAUMA:- fractures involving nasal
bones are common. due to the direct
blow nasal bones are displaced
downward and inward.
• Lateral fractures also occur in which
one nasal bone is driven inward and
the other outward.
• Nasal septum is usually involved.
www.indiandentalacademy.com
37. • INFECTION:- common cold(rhinitis) is
the commonest infection of the nose.
• Hypertrophy of mucosa over the inferior
nasal concha is a common feature of
allergic rhinitis characterized by
sneezing blockage and excessive
discharge from nose.
• Infection of nasal cavity can spread in a
variety of directions. Paranasal sinuses
are especially prone to infection.
• Organisms may spread via the nasal part
of the pharynx and the auditory tube to
the middle ear
www.indiandentalacademy.com
38. • It is also possible to ascend to the meninges of
the anterior cranial fossa, along the sheaths of
the olfactory nerves through the cibriform
plate, and produce meningitis.
• Dangerous area of face:- deep connections of
the facial vein include a) comm between
supraorbital and superior opthalamic veins
b) with the pterygoid venous plexus through
the deep facial vein. The facial vein comm with
the cavernous sinus through these
connections.
Infections of the upper lip and in lower part of
the nose can spread in retrograde direction
and cause thrombosis of the cavarnous sinus.
