Back 6

Nasal cavity

Front 7

Nasal cavity Posteriorly communicates with the pharynx through an opening called?

2. oropharynx

3. laryngopharynx

Front 9

Lies posterior to the nasal cavity and extends to the soft palate.

Back 9

Nasopharynx

Front 10

posterior to the oral cavity and extends from the soft palate inferiorly to the level of the hyoid bone.

Back 10

Oropharynx

Front 11

begins at the level of the hyoid bone. At its inferior end it opens into the esophagus posteriorly and the larynx anteriorly.

Back 11

Laryngopharynx

Front 15

Consists of two fused plates of hyaline cartilage that form the anterior wall of the larynx.

Back 15

Thyroid cartilage

Front 16

large, leaf shaped piece of elastic cartilage that is covered with epithelium.

Back 16

epiglottis

Front 17

Ring of hyaline cartilage that forms the inferior wall of the larynx.

Cricoid cartilage

Front 18

triangular pieces of mostly hyaline cartilage located at the posterior, superior border of the cricoid cartilage.

arytenoid cartilages

Front 19

horn-shaped pieces of elastic cartilage, are located at the apex of each arytenoid cartilage.

Back 19

Corniculate cartilages

Front 20

club-shaped elastic cartilages anterior to the corniculate cartilages, support the vocal folds and lateral aspects of the epiglottis.
