Question | Answer |
Where is the Upper Respiratory System located? | SUPERIOR to the Thorax |
What is the Histology of the Upper Respiratory System? | Mucous Membrane; Cilia, Goblet Cells |
What is the histology of the Mucous Membrane in the Upper Respiratory System? | Simple Ciliated Columnar Epithelium |
What is the function of the Cilia in the Upper Respiratory System? | ESCALATOR to move Particles toward OUTSIDE |
What is the function of Goblet Cells? | secrete a Mucus coating to TRAP Air born Particles |
What structure clean and remove debris from the air we breathe? | Mucous Membrane, Cilia, Goblet Cells |
What are the gross anatomical parts of the UPPER Respiratory system? | 1. Nasal Cavity; 2. Pharynx; 3. Larynx; 4. Trachea |
What is the function of the Nasal Cavity? | DRAINAGE site of Lacrimal and Sinus Canals |
What are the main parts of the Nasal Cavity? | 1. Nasal Septum; 2. Nasal Conchae; 3. Olfactory Receptors |
What structures compose the Nasal Septum? | 1. Perpendicular Plate; 2. Vomer; 3. Hyaline Cartilage |
What is the function of the Nasal Conchae? | Filter and Humidify incoming air |
Why are the Nasal Conchae shaped funny? | to multiply Surface Area = better Filtration |
What is the function of the Olfactory Receptors? | connect to Olfactory Bulb via Cribriform Plate (Ethmoid) |
Why do we sniff to smell? | sniffing brings the air up HIGHER to reach Olfactory Receptors |
