Frontal
Ethmoid Maxillary Sphenoid Temporal |
|
|
What space(s) are there in the frontal bone?
|
Right and left frontal sinuses
|
|
|
What space(s) are there in the ethmoid bone?
|
Ethmoid air cells
|
|
|
What space(s) are there in the maxillary bone?
|
Maxillary sinus
|
|
|
What space(s) are there in the sphenoid bone?
|
Right and left sphenoid sinuses
|
|
|
What space(s) are there in the temporal bone?
|
Auditory tube
Middle Ear Mastoid air cells |
|
|
How is the external auditory meatus divided (hint: by composition)
|
Cartilaginous EAM
Bony EAM |
|
|
Through what foramen does cranial nerve VII exit?
|
The stylomastoid foramen
|
|
|
What are the main structures of the airway from top to bottom?
|
Mandible
Hyoid bone Thyroid cartilage Cricoid cartilage Trachea Thyroid gland Sternum |
|
|
What are the main spaces through which air flows in the airway from top to bottom?
|
Nasal cavity
Choana Pharynx Laryngeal aditus Vestibule Rima vestibuli Ventricle Rima glottidis Infraglottic space Trachea |
|
|
What are the surfaces in the airway past which air flows from top to bottom?
|
Conchae
Palate Uvula Tongue Palatine tonsils Epiglottis False vocal fold True vocal fold Cricoid cartilage |
|
|
What are the different regions of the spaces in the airway?
|
Nasal cavity
Oral cavity Nasopharynx Oropharynx Laryngopharynx Larynx and Trachea |
|
|
What structure(s) divides the oral cavity and the pharynx?
|
Hard palate, soft palate, uvula
|
|
|
What can be visualized on either side of the uvula? List three structures.
|
Palatopharyngeal arch
Palatine tonsil Palatoglossal arch |
|
|
Where are the lingual tonsils located?
|
Below the palatine tonsils, at the base of the tongue exposed to the airway
|
|
|
Where is the torus tubarius? What opening is nearby?
|
It is in the nasal cavity
The auditory tube is nearby |
|
|
Where are the pharyngeal tonsils and the Eustachian tube orifices located relative to the nasal septum?
|
The pharyngeal tonsils are located at the back of the throat in line with the nasal septum as it empties into the pharynx
The Eustachian tube orifices are on either side of the nasal canals on the lateral sides of the nasopharynx |
|
|
Where is the epiglottis located relative to the opening of the larynx?
|
It is anterior, at the base of the tongue muscle
|
|
|
Which is superior, the true or false vocal folds?
|
The false vocal folds are superior to the true vocal folds
|
|
|
What cartilaginous structure is located superior to the cricoid cartilage and is an attachment for the vocal cords?
|
Arytenoid cartilage
|
|
|
What are the components of the laryngeal skeleton?
|
Hyoid bone
Epiglottis Arytenoid cartilage Thyroid cartilage Cricoid cartilage Cricothyroid joint Trachea |
|
|
What structures control the shape of the airway?
|
Epiglottis
Aryepiglottic membrane Cuneiform tubercle Vocal folds Transverse arytenoid muscle |
|
|
Where are the posterior cricoarytenoid muscles located and what motion do they effect?
|
They are located posteriorly, on the cricoid and arytenoid cartilage
Contraction opens the glottis to breathe - abducts the vocal folds |
|
|
Where are the transverse arytenoid muscles and what motion do they effect?
|
They are located across the arytenoid cartilage
Contraction causes the airway to close for swallowing, and adducts the vocal folds |
|
|
What are some vessels that make tracheotomies risky?
Which is one of the ones to be most concerned about? |
Superior, inferior thyroid arteries
Thyroid ima artery Brachiocephalic trunk Superior, middle, inferior thyroid veins *Most concerning! Thyroid ima artery - on a regular basis, it's location is medial enough and close enough to the incision to make it a liability |
