Front 2

Briefly describe the functions performed by the paranasal sinuses

Name the coarse hairs that protrude into the nasal cavity from the epithelium

Back 4

Vibrissae (plural)

Front 5

Briefly describe the function of the vibrissae (nasal cavity hairs)

Back 5

They are coated with mucus, which traps inhaled particles so they cannot travel deeper into the respiratory system

Front 6

Identify the cells in the epithelial layer that secrete watery mucus

Back 6

Goblet cells

Front 7

Briefly describe the function of the mucus that coats the nasal epithelium

Back 7

The mucus traps enhaled particles and humidifies inhaled air

Front 8

Briefly describe how the blood vessels in the nasal cavity prepares enhaled air so it can safely enter the lungs

Back 8

The vessels radiate heat , which warms the incoming air to near body temperature

Front 9

Briefly describe the function of the celia that extend from the epithelial cells of the nasal cavity

Back 9

They sweep the particle - laiden mucus to the throat, where it is swallowed

Front 10

Identify the tissue that lines the superior region of the nasal cavity

Back 10

Olfactory Mucosa

Front 11

Identify the specialized nerve cell that is found in the olfactory mucosa

Back 11

Olfactory receptor

Front 12

Identify the region of the pharynx that extends from the soft palatine to the epiglottis

Back 12

Oropharynx

Front 13

The openings in the layer walls of the nasopharynx connect to what tubes?

Back 13

Auditory or eustachian tubes

Front 14

Identify the lymphatic masses that are embedded in the lateral walls of the pharynx

Back 14

Palatine tonsils

Front 15

Identify the large, shield-shaped cartilage that supports most of the laryngeal wall

Back 15

Thyroid cartilage

Front 16

Identify the portion of the laryngeal cartilage that angles forward and forms the protrusion of the neck called the "adam's apple"

Back 16

Laryngeal prominence

Front 17

Identify the ring-shaped cartilage that supports the inferior portion of the larynx

Back 17

Cricoid cartilage

Front 18

Identify the broad, posterior portion of the cricoid cartilage

Back 18

The lamina

Front 19

Identify the small, pyramid-shaped cartilage that is located along the back wall of the larynx

Back 19

Arytenoid cartilage

Front 20

Identify the small, elastic cartilage that is embedded in the lateral membranes and folds of the larynx

Back 20

Cuneiform cartilage

Front 21

Identify the leaf-shaped flap of cartilage that projects obliquely from the top of the larynx

Back 21

Epiglottis

Front 22

Describe the function of the epiglottis

Back 22

During the swallowing process, it is forced downward to close the opening to the larynx (respiratory tract)

Front 23

Identify the superior pair of folds that protrude into the lumen of the larynx

Back 23

Vestibular folds (false vocal cords or folds)

Front 24

Briefly describe the composition of the vestibular folds

Back 24

A thick layer of mucosa membrane and an enclosed vestibular ligament

Front 25

Briefly describe the function of the vestibular folds

Back 25

Lubricate the vocal folds with mucus and help prevent food from passing deeper into the respiratory tract

Front 26

Identify the inferior pair of folds that protrude into the lumen of the larynx

Back 26

Vocal folds (true vocal cords)
