The bridge of the nose Superiorly each bone articulates with the frontal bone.
BY- DR SUDEEP K.C.. The Nasal Cavity: Functions  The superior part of the respiratory tract  A passageway for air to lungs  Filters impurities esp.
THE RESPIRATORY SYSTEM The complex of organs and tissue which are necessary to exchange blood carbon dioxide (CO2) with air oxygen (O2) is called the respiratory.

I.M. SECHENOV FIRST MOSCOW STATE MEDICAL UNIVERSITY ENT Department Clinical anatomy, physiology and methods of examination of nose and paranasal sinuses

Nasal pyramid skeleton nasal bone lateral cartilage cartilage alaris cartilage accessorius septum cartilage

Blood supply of external nose Ухо человека подразделяют на три отдела: наружное, среднее и внутреннее. A. ophthalmica branche: a. dorsalis nasi A. facialis branches : a. labialis superior a. angularis a. nasalis lateralis

Nasal valve First air flow regulation Determine of air flow resistance Making conditions for slowing and deepening of breath, effective air metabolism and dispersion of surphactant in alveoluses

Septum nasi Ухо человека подразделяют на три отдела: наружное, среднее и внутреннее.

Nerves and vessels of septum Ухо человека подразделяют на три отдела: наружное, среднее и внутреннее. External carotid artery a.sphenopalatina a. palatina major a. labialis superior Internal carotid artery a.a ethmoidales anterior et posterior Nervus maxillaris n. nasopalatinus Scarpae nn. alveolares superiores Nervus olphactorius n.n ethmoidales anterior et posterior Nervus olfactorius

Lateral wall of nasal cavity Ухо человека подразделяют на три отдела: наружное, среднее и внутреннее. 1 – middle turbinate 2 – Inferior turbinate 3 - superior turbinate 4 – canalis nasolacrimalis 5 – osteomeatal complex 6 – frontal sinus ostium 7 – sphenoid sinus ostium 8 – Lamina cribrosa

Nerves and vessels of the lateral nasal cavity wall Ухо человека подразделяют на три отдела: наружное, среднее и внутреннее. Nervus maxillaris rami nasales posteriores superiores et inferiores Nervus ophtalmicus n.n ethmoidales anterior et posterior Nervus olfactorius A. carotis externa a.sphenopalatina A. carotis interna a.a ethmoidales anterior et posterior

Ostiomeatal complex Include : Anterior part of middle turbinate Upper surface of inferior turbinate Processus uncinatus Agger nasi Hiatus semilunaris Ethmoid bulla and area between bulla and lamina basalis of middle turbinate

Ethmoid labyrinth FS – sinus frontalis, SS – sinus sphenoidalis; A – anterior ethmoid cells; AN – agger nasi; P – posterior ethmoid cells; IT – inferior turbinate; BL – Lamina basalis; B – bulla ethmoidalis.

Maxillary sinus 1 – Maxillary sinus; 2 – ethmoid sinuses; 3 – canalis infraorbitalis ; 4 – recessus alveolaris; 5 – inferior nasal meatus; 6 – turbina; 7 – conha nasalis media; 8 – middle nasal meatus; 9– Septum; 10 – Orbit.

Maxillary sinus Canalis infraorbitalis

Frontal sinus, agger nasi cells Ухо человека подразделяют на три отдела: наружное, среднее и внутреннее. 1 – Sinus frontalis; 2 – ostium of sinus frontalis; 3 – Recessus frontalis; 4 – agger nasi cells; 5 – bulla ethmoidalis.

Sphenoid sinus
