Nasal Sinus OR Paranasal Sinus :-
So What Is Sinus ?
Really Need To Know.
Sinus -
Sinus Is A Sac OR Cavity In Any Organ OR Tissue That Are Called Sinus.
Good Now You Know Sinus Meaning, Than We Go To Know Meaning Nasal Sinus OR Paranasal Sinus.
Nasal Sinus -
Nasal - Nose (Nasal Meaning Nose)
Sinus - Sac OR Cavity (Sinus Meaning Sac OR Cavity).
Surrounding Nose Found Sac OR Cavity And They Are Called As Nasal Sinus.
Paranasal Sinus -
Para - Pair (Para Meaning Pair)
Nasal - Nose (Nasal Meaning Nose)
Sinus - Sac OR Cavity(Sinus Meaning Sac OR Cavity).
Surrounding Nose Found Sac OR Cavity In Pair And They Are Called As Paranasal Sinus.
Nasal Sinus OR Paranasal Sinus Both Word Are Similar, Nasal Sinus Also Known As Paranasal Sinus.
Type of Nasal Sinus OR Paranasal Sinus -
There Are 4 Main Type of Nasal Sinus OR Paranasal Sinus, And They Are In Pair.
(1). Maxillary Sinus
(2). Ethmoid Sinus
(3). Frontal Sinus
(4). Sphenoid Sinus
These Sinus Gives Name According To Bones Within Which They Lie.
Nasal OR Paranasal Sinus Are Lined With Cell That Make Mucus To Keep The Nose From Drying Out During Breathing.
(1). Maxillary Sinus -
This Is First Type of Nasal Sinus OR Paranasal Sinus.
Maxillary Sinus Is A Longest Sinus.
Location of Maxillary Sinus Is
Under The Eye In Maxillary Bone OR Lateral Wall of Nose In Maxillary Bone.
Important Things Semilunar Hiatus Is Connect Maxillary Sinus To The Nose, And This Semilunar Hiatus Are Found Between Nose And Maxillary Sinus.
How Air Travel In Maxillary Sinus -
We Inhale Air And This Air Go In Nose Than Semilunar Hiatus Than Maxillary Sinus, So This Is Process We Are Called Maxillary Sinus Air Filled Cavity.
Important Fact That Is, In Maxillary Sinus There Are No Other Way To Exit Air,
Air Enter In Maxillary Sinus This Is Only Way To Return Air In Nose.
How Air Exit In Maxillary Sinus -
Maxillary Sinus Air Go To Semilunar Hiatus Then Nose.
(2). Ethmoid Sinus -
This Is Second Type of Nasal Sinus OR Paranasal Sinus.
Location of Ethmoid Sinus Is
Hollow Space In The Bones Around The Nose OR Found Within Ethmoid Bone Between Nose And Eye.
Ethmoid Sinus Divided Into 3 Type According To There Position
(A). Anterior Ethmoid Sinus
(B). Middle Ethmoid Sinus
(C). Posterior Ethmoid
Semilunar Hiatus / Hiatus Semilunaris Connect Anterior Ethmoid Sinus To The Nose,
Hiatus Semilunaris Found Between Anterior Ethmoid Sinus And Nose.
Ethmoid Bulla Connect Middle Ethmoid Sinus To The Nose,
Ethmoid Bulla Found Between Middle Ethmoid Sinus And Nose.
Superior Meatus Connect Posterior Ethmoid Sinus To The Nose,
Superior Meatus Found Between Posterior Ethmoid Sinus And Nose.
How Air Travel In Ethmoid Sinus -
We Inhale Air And This Air Go In Nose Than Anterior/Middle/Posterior Than Ethmoid Sinus, So This Is Process We Are Called Ethmoid Sinus Air Filled Cavity.
Important Fact That Is, In Ethmoid Sinus There Are No Other Way To Exit Air,
Air Enter In Ethmoid Sinus This Is Only Way To Return Air In Nose.
How Air Exit In Ethmoid Sinus -
Ethmoid Sinus Air Travel Exit In Anterior/Middle/Posterior Than In Nose.
(3) Frontal Sinus -
This Is Third Type of Nasal Sinus OR Paranasal Sinus.
Frontal Sinus Is Triangular In Shape.
Location of Frontal Sinus Is Just Behind The Eye In The Brow Region OR Under The Forehead.
Frontal Sinus Connect With Nasal Cavity Via The Frontonasal Duct Which Open Out At The Hiatus Semilunaris On The Lateral Wall of Nose.
How Air Travel In Frontal Sinus -
We Inhale Air Air Goes In Nose Than Hiatus Semilunaris Than Frontonasal Duct Than Frontal Sinus, So This Process We Are Called Frontal Sinus Air Filled Cavity.
Air Enter In Frontal Sinus This Is Only Way To Return Air In Nose.
How Air Exit In Frontal Sinus -
Air of Frontal Sinus Travel Exit In Frontonasal Duct Than Semilunar Hiatus Than In Nose.
(4). Sphenoid Sinus -
This Is Fourth Type of Nasal Sinus OR Paranasal Sinus.
Location of Sphenoid Sinus Is Behind The Nose Between The Eye In Sphenoid Bone.
Important Fact That Is, In Sphenoid Sinus There Are No Other Way To Exit Air,
Air Enter In Sphenoid Sinus This Is Only Way To Return Air In Nose.
Just Behind Nose Internal Nares A Hole Is Present This Called Choana, This Is Connect Nose To Sphenoid Sinus.
How Air Travel In Sphenoid Sinus -
We Inhale Air And Air Goes In Nose Than Choana Than Sphenoid Sinus This Process We Called Sphenoid Sinus Air Filled Cavity.
How Air Exit In Sphenoid Sinus -
Air In Sphenoid Sinus Travel Exit In Choanae Than Nose.
Function of Nasal Sinus OR Paranasal Sinus -
Nasal Sinus OR Paranasal Sinus Have 3 Main Function.
(1). Sinus Help In Speech -
Sinus Help In Speech And Airplay Most Important Role.
Voice Sound Is Amplified And Modified By Sinus.
How SInus Help In Speech You Can Understand By Sinusitis Condition, Inflammation of Mucous Membrane That Lines The Sinus Called Sinusitis.
Reason Behind Sinusitis Condition
- Cold
- Season Changes
- Smoking Etc.
Than As You Can See General Sign And Symptoms Like,
- Nose Running
- Mucus Plugged Nose
- Facial Pain
- Fever Etc.
Later This Condition Change Sound Like
Voice May Be Louder, Soft, Thick.
This Is Proof Sinus Help In Speech.
As A Normal Sinus There Are No Any Difficulty, Person Speak Easy And Sound May Be Good With No Change,
And In Other Condition Like Sinus Disease OR Any Error In Sinus Person Present Difficulty In Speak And Sound Change You Can See.
(2). Sinus Lighten The Skull -
Sinus Are Present In Human Skull And They Are Sac OR Cavity That Mean They Have Noting Inside Anything Just Only Air So They Are Air Filled Cavity.
So That Sinus Lighten The Skull.
(3). Sinus Protect Nose From Microorganism -
Sinus Surrounding Found Cells That Cover Sinus And Secrete Mucus, So Whole Sinus Is Covered By Mucus Layer. That Mucus Layer Help To Keep Nose Moisturized And Also Protect Nose From Pollutants, Microorganism Etc.
