Frontal Sinus, Maxillary Sinus, Anterior Ethmoid Air Cells

4
Q

What is the Ethmoid Bulla?

A

A bulge created by the Ethmoid Air cells

5
Q

What are the 2 main sources for arteries to the nasal cavity?

A

Maxillary and Anterior & Posterior Ethmoid arteries

6
Q

What are the two main arterial branches off of the Maxillary artery that supplies blood to the nasal cavity

A

Sphenopalatine and Greater Palatine artery

7
Q

What is the pathway of the Maxillary Artery to provide blood to the nasal cavity?

A

Infratemporal Fossa –> Pterygopalatine Fossa –> Sphenopalatine Foramen

8
Q

Does the facial artery send branches to septum?

A

Yes. It sends some branches from the superior labial artery to the septum. However, this is not considered one of the major sources.

9
Q

What branches off of the Sphenopalatine artery as it runs along the septum?

A

Lateral Posterior nasal branches

10
Q

What branch of the Internal Carotid artery supplies blood to the nasal cavity?

A

Opthalmic –> Anterior and Posterior ethmoidal arteries

11
Q

What cranial nerve gives General Sensory to the nasal cavity?

A

Trigeminal - V1 and V2

12
Q

The nasopalatine nerve is a branch of what cranial nerve?

A

Cranial Nerve V-V2

13
Q

The Anterior Ethmoidal Nerve is a branch off of what cranial nerve?

A

CN V-V1. Also a branch off of Nasocilliary nerve

14
Q

What nerve sends branches to Posterior and Inferior Septum then continues to Incisive Canal?

A

Nasopalatine Nerve

15
Q

Posterior Lateral Nasal nerve is a branch off of what Cranial Nerve?

A

CN V-V2.

16
Q

What nerve sends internal nasal branches to anterior and superior septum and lateral walls?

A

Anterior Ethmoidal Nerve

17
Q

What are the three specific nerve branches that supply general sensory to the nasal cavity?

A

Anterior Ethmoidal Nerve, Nasopalatine nerve and Posterior Lateral Nasal nerve

18
Q

The Anterior Ethmoidal nerve is a branch off of what specific branch of the V1 nerve?

A

Nasocilliary nerve

19
Q

What nucleus are the Preganglionic cell bodies of CN VII housed in before they supply parasympathetic innervation to the Smooth Muscle and Glands of Nose?

A

Superior Salivatory Nucleus

20
Q

What cranial nerve supplies Parasympathetic innervation to the smooth muscle and glands of nose?

A

CN VII

21

Pre-ganglionic parasympathetic fibers synapse with Post-ganglionic fibers in what ganglion that ends up going to nasal cavity?

A

Pterygopalatine ganglion

22
Q

What sympathetic ganglion do sympathetic fibers that end up in the nasal cavity synapse in?

A

Superior Cervical Ganglia

23
Q

What are the four paranasal sinuses?

A

Frontal, Sphenoidal, Ethmoidal and Maxillary
