For Upper Respiratory Tract under Gross Anatomy, name the different paranasal sinuses with their corresponding drainage sites. Make a comprehensive table.
Understand the Problem
The question is asking for a detailed table that lists the various paranasal sinuses along with the anatomical sites where they drain. This involves knowledge of human anatomy, particularly the anatomy of the upper respiratory tract.
Answer
Frontal sinus drains into the middle meatus, Maxillary sinus into the middle meatus, Sphenoid sinus into the sphenoethmoidal recess, and Ethmoid sinuses: anterior into the middle meatus, posterior into the superior meatus.
| Paranasal Sinus | Drainage Site |
|---|---|
| Frontal Sinus | Drains into the middle meatus via the frontonasal duct |
| Maxillary Sinus | Drains into the middle meatus │ |
| Sphenoid Sinus | Drains into the sphenoethmoidal recess |
| Ethmoid Sinuses | Anterior: Drains into the middle meatus, Posterior: Drains into the superior meatus |
Answer for screen readers
| Paranasal Sinus | Drainage Site |
|---|---|
| Frontal Sinus | Drains into the middle meatus via the frontonasal duct |
| Maxillary Sinus | Drains into the middle meatus │ |
| Sphenoid Sinus | Drains into the sphenoethmoidal recess |
| Ethmoid Sinuses | Anterior: Drains into the middle meatus, Posterior: Drains into the superior meatus |
More Information
In the human skull, paranasal sinuses have significant roles such as lightening the skull, humidifying and heating inhaled air, and enhancing voice resonance. Problems with sinus drainage can lead to sinusitis.
Tips
A common mistake is confusing the drainage site of the ethmoid sinuses. Remember, they differ by anterior and posterior parts.
