Nose Flashcards
Major contributors to Nasal Septum/Medial Wall Formation
Perpendicular Plate of Ethmoid Bone
Vomer Bone
Septal Cartilage
Septal Cartilage is also known as
Quadrilateral Cartilage
Minor Contributors to Nasal Septum/Medial Wall formation
Crest of Nasal Bone
Crest of Maxilla Bone
Crest of Palatine Bone
Nasal Spine of Frontal Bone
Rostrum of Sphenoid Bone
Schidylesis Joint is present between
Sphenoidal Rostrum and Vomer Bone
Schidylesis Joint is Ridge and Groove Suture
Highly vascular area in the Antero-Inferior aspect of Nasal Septum is
Little’s Area
Why Little’s Area is highly vascular
Due to presence of anastomosis ~ Kiesselbach’s Plexus
Arteries involved in the Kiesselbach’s plexus
- Anterior Ethmoidal Artery ← ophthalmic artery ← ICA
- Sphenopalatine Artery ← Maxillary art. ← ECA
- Greaterplatine Artery ← Maxillary art. ← ECA
- Septal branch of Superior Labial Artery ← Facial art. ← ECA
All Arteries involved in the Kiesselbach’s plexus are branches of ECA except
- Anterior Ethmoidal Artery ← Ophthalmic artery ← ICA
Artery of Epistaxis is
Sphenopalatine Artery
Major Contributors to Lateral wall of Nasal Cavity
Superior Turbinate
Middle Turbinate
Inferior Turbinate
Superior and Middle Turbinates are part of
Ethmoid Bone
Whereas inferior turbinate is separate bone
Minor contributions to the lateral wall is done by
L ~ Lacrimal bone
M~ Maxilla
N~ Nasal bone
Perpendicular plate of palatine bone
Medial Pterygoid plate
Uncinate process is extension from
Middle Turbinate
Uncinate process is articulating posteriorly with the
Inferior Turbinate
Uncinate process is articulating Anteriorly with the
Lacrimal Bone
Sphenopalatine Foramen Location and Structures passing through it
Between the Sphenoid and Palatine Bone
Sphenopalatine nerves and vessels
Duct opening in the Inferior Meatus
Nasolacrimal Duct
Name the valve present in Nasolacrimal Duct
Valve of Hasner
Bulla Ethmoidalis present in __________ Meatus
