<p>The respiratory mucosa in the nasal cavity is composed of ciliated pseudostratified columnar epithelium, goblet cells, and a rich vascular supply. It functions to humidify and warm the incoming air, as well as to trap and remove particles and pathogens from the air.</p> Signup and view all the answers

<p>The nasal cavity is innervated by a mix of sensory and secretomotor nerves, including CN I for special sensory (smell), CN V1 and V2 for somatic sensory, CN VII for parasympathetic secretomotor, and sympathetic fibers from the superior cervical ganglion. This complex innervation allows for the detection of smells, regulation of nasal secretions, and sensation of touch, pain, and temperature.</p> Signup and view all the answers

<p>The nasal cavity contains specialized olfactory mucosa on the roof, which houses the olfactory nerve (CN I) and is responsible for the sense of smell. Additionally, it contains various foramina and gateways for vascular and nerve supply, including the foramen cecum, cribriform plate, and sphenopalatine foramen, which facilitate the passage of nerves and blood vessels.</p> Signup and view all the answers

<p>The nasal cavity receives arterial supply from branches of the external and internal carotid arteries, forming anastomoses in the Little's area. Venous drainage from the nasal cavity includes routes to the cavernous sinus, pterygoid plexus, and facial vein. The anastomoses in the Little's area are significant for providing collateral circulation and preventing potential ischemic events in the nasal cavity.</p> Signup and view all the answers

<p>Nasal muscles, innervated by the facial nerve, control the flaring or constriction of the nostrils, which helps regulate airflow through the nasal cavity. This function is essential for adjusting the resistance to airflow and optimizing the process of breathing.</p> Signup and view all the answers
