Laterale Wand der Nasenhöhle

This video tutorial provides a comprehensive overview of the anatomy of the nasal cavity, focusing on the lateral wall. It covers the bones, cartilage, and soft tissues that form the lateral wall, as well as the nasal conchae and passages. The tutorial also explains the bony framework of the nasal cavity and introduces key nasal cartilage components, highlighting their roles in the structure and function of the nasal cavity.

Which structure is described as pear-shaped in the nasal cavity?

• Lehmann nasi

• Nasal conula

• Vestibulum nasi

• Apertura Piriformis

What is the primary role of the nasal conchae?

• To regulate airflow and humidify the air

• To support the nasal septum

• To connect the nasal cavity to the sinuses

• To separate the nasal and oral cavities

Which nasal concha is primarily responsible for humidifying and purifying the air?

• Superior nasal concha

What is the role of the lamina cribrosa in the nasal cavity?

Which sinus opens into the upper nasal passage?

• Sphenoid sinus

• Frontal sinus

• Maxillary sinus

What is the function of the Plica Lacrimalis?

• To moisten the air we breathe

• To connect the nasal cavity to the sinuses

• To prevent air from entering the naso lacrimal duct

• To support the nasal septum

Which cartilage forms the tip of the nose?

• Cartilago Alaris Minor
