Name the thin, curved bony plates that protrude into the nasal cavity
|
Superior, middle, and inferior turbinates; or nasal conchae
|
|
Briefly describe the functions performed by the paranasal sinuses
|
They lighten the skull, secrete mucus into the nasal cavity, and resonate the voice
|
|
Identify the epithelial tissue that lines the anterior portion of the nasal cavity
|
Stratified squamous epithelium
|
|
Name the coarse hairs that protrude into the nasal cavity from the epithelium
|
Vibrissae (plural)
|
|
Briefly describe the function of the vibrissae (nasal cavity hairs)
|
They are coated with mucus, which traps inhaled particles so they cannot travel deeper into the respiratory system
|
|
Identify the cells in the epithelial layer that secrete watery mucus
|
Goblet cells
|
|
Briefly describe the function of the mucus that coats the nasal epithelium
|
The mucus traps enhaled particles and humidifies inhaled air
|
|
Briefly describe how the blood vessels in the nasal cavity prepares enhaled air so it can safely enter the lungs
|
The vessels radiate heat , which warms the incoming air to near body temperature
|
|
Briefly describe the function of the celia that extend from the epithelial cells of the nasal cavity
|
They sweep the particle - laiden mucus to the throat, where it is swallowed
|
|
Identify the tissue that lines the superior region of the nasal cavity
|
Olfactory Mucosa
|
|
Identify the specialized nerve cell that is found in the olfactory mucosa
|
Olfactory receptor
|
|
Identify the region of the pharynx that extends from the soft palatine to the epiglottis
|
Oropharynx
|
|
The openings in the layer walls of the nasopharynx connect to what tubes?
|
Auditory or eustachian tubes
|
|
Identify the lymphatic masses that are embedded in the lateral walls of the pharynx
|
Palatine tonsils
|
|
Identify the large, shield-shaped cartilage that supports most of the laryngeal wall
|
Thyroid cartilage
|
|
Identify the portion of the laryngeal cartilage that angles forward and forms the protrusion of the neck called the "adam's apple"
|
Laryngeal prominence
|
|
Identify the ring-shaped cartilage that supports the inferior portion of the larynx
|
Cricoid cartilage
|
|
Identify the broad, posterior portion of the cricoid cartilage
|
The lamina
|
|
Identify the small, pyramid-shaped cartilage that is located along the back wall of the larynx
|
Arytenoid cartilage
|
|
Identify the small, elastic cartilage that is embedded in the lateral membranes and folds of the larynx
|
Cuneiform cartilage
|
|
Identify the leaf-shaped flap of cartilage that projects obliquely from the top of the larynx
|
Epiglottis
|
|
Describe the function of the epiglottis
|
During the swallowing process, it is forced downward to close the opening to the larynx (respiratory tract)
|
|
Identify the superior pair of folds that protrude into the lumen of the larynx
|
Vestibular folds (false vocal cords or folds)
|
|
Briefly describe the composition of the vestibular folds
|
A thick layer of mucosa membrane and an enclosed vestibular ligament
|
|
Briefly describe the function of the vestibular folds
|
Lubricate the vocal folds with mucus and help prevent food from passing deeper into the respiratory tract
|
|
Identify the inferior pair of folds that protrude into the lumen of the larynx
|
Vocal folds (true vocal cords)
|
