|
painful inflammation
, sinusitis. pic |

is lined by |
typical respiratory epithelium
In areas subjected to abrasions, a _____ ___ ___ may occur. |
nonkeratinizing stratified squamous
|
|
Nasopharynx
Underlying connective tissue contains |
mucous, serous
mixed glands. |
|
|
Nasopharynx
The lymphatic tissue is irregularly scattered throughout and also form |
tonsillar structures
(pharyngeal tonsils or adenoids) on the posterior wall. |
|
|
Nasopharynx
palatine and lingual tonsils at the junction of the oral cavity and pharyngeal tonsil in the nasopharynx collectively forms a protective ring________ ________ guarding access to the lower reaches of respiratory and oral cavities. |
(Waldeyer’s ring)

|
|
Larynx
The two main functions of the larynx are |
to produce sound
2. to close the trachea during swallowing to prevent food and saliva from entering the airway. |
|
|
Larynx
The wall of the larynx is made up of the |
thyroid and cricoid hyaline cartilage and the elastic cartilage core of the epiglottis extending over the lumen
|
|
|
Extrinsic laryngeal muscles attach the larynx to the hyoid bone to
|
raise the larynx during swallowing.
|
|
|
Intrinsic laryngeal muscles
|
abductor
adductors tensors link the _____ & _____ = |
thyroid
cricoid cartilages When intrinsic muscles contract, the tension on the vocal cords changes to modulate phonation. |
|
The larynx can be subdivided into three regions:
|
supraglottis,
glottis subglottis Stratified unkeratinized & keritanized & vocal cord change |
The supraglottis, which includes the epiglottis, false vocal cords (or folds), and laryngeal ventricles.
The glottis, consisting of the true vocal cords (or folds) and the anterior and posterior commissures. The subglottis, the region below the true vocal cords, extending down to the lower border of the cricoid cartilage. During forced inspiration, vocal cords are abducted, and the space between the vocal cords widens. |

false vocal cords the epiglottis, false vocal cords (or folds), laryngeal ventricles. |
|
|
glottis
|
true vocal cords (or folds) and
anterior commissures posterior commissures. During forced inspiration, vocal cords are = |
abducted,
and the space between the vocal cords widens. |
|
subglottis
|
the region below the true vocal cords, extending down to the lower border of the cricoid cartilage.

vocal cords a cover consisting of |
-stratified squamous
-superficial layer of the lamina propria, aka = Elsewhere, the epithelium is pseudostratified ciliated, with goblet cells. = |

pseudostratified ciliated, with goblet cells. |
|
Larynx
Laryngeal seromucous glands are found throughout the lamina propria, except at the level of the = |
true vocal cords.

Larynx
Laryngea contains l________ glands |
seromucous
|
|
|
lamina propria of the true vocal cords consists of three layers:
|
superficial =
intermediate = deep = |
-extracellular matrix
-few elastic fibers -abundant elastic and collagen fibers |
|
_____ _______ are responsible for vocal cord vibration.
|
Reinke's space
& the epithelial covering |
|
|
Reinke's edema
|
viral infection
, trauma (laryngeal endoscopy), severe coughing cause what to occur |
fluid to accumulate in the superficial layer of the lamina propria.
|
|
Reinke's space
Both the intermediate and deep layer of the lamina propria constitute the |
vocal ligament.
The lamina propria is usually rich in = |
mast cells
|
|
Mast cells participate in
|
hypersensitivity reactions leading to edema and laryngeal obstruction, a potential medical emergency.
|
|
|
Croup designates a
|
laryngotracheobronchitis
in children, in which an inflammatory process = |
narrows the airway and produces inspiratory stridor.
|
|
Epiglottis
projects from the rim of the |
larynx
extends into the = |
pharynx
and has both a lingual and a laryngeal surface. |
|
Epiglottis
entire lingual surface and the apical portion of the laryngeal surface are covered with |
stratified squamous epithelium.
|
|
|
Epiglottis
Toward the base of the epiglottis on the laryngeal surface, the epithelium undergoes a transition into |
ciliated pseudostratified columnar epithelium.
|
|
|
_______ & __________ glands are found beneath the epithelium. Core contains elastic cartilage.
|
Mixed mucous glands
serous glands pic |
