Nerves of nasal cavity (preview) - Human Anatomy | Kenhub

Summary

In this Kenhub tutorial, Nicole explores the nerves of the nasal cavity, highlighting its anatomy and functions. The nasal cavity, with its nasal septum, warms, humidifies, and filters air, housing the olfactory epithelium for smell. Key structures like the sphenoidal sinus and maxilla are identified. The tutorial also touches on clinical notes, aiming to educate and engage anatomy enthusiasts.

Takeaways

• 👃 The nasal cavity is part of the respiratory system, with two paired cavities located on either side of the nasal septum.
• 🌡️ The primary function of the nasal cavity is to warm, humidify, and filter the air as it enters through the nostrils.
• 🕷️ The nasal cavity's ability to filter air is due to the hair and mucous lining of its internal walls, which remove allergens before the air reaches the lungs.
• 👃 The olfactory epithelium, located in the nasal cavity, is responsible for the sense of smell.
• 💧 The nasal cavity also produces mucus to aid in filtering the air.
• 🦴 The nasal septum is composed of septal cartilage and bones such as the vomer and ethmoid bone.
• 🦴 The maxilla and palatine bones contribute to the formation of the hard palate, which separates the nose from the mouth.
• 🔍 The tutorial includes an image of the nasal cavity, highlighting structures like the nasal septum, lateral wall, sphenoidal sinus, and maxilla.
• 📚 The tutorial also discusses relevant clinical notes after covering the anatomy of the nasal cavity.
• 🎥 The full tutorial, along with more videos, quizzes, articles, and atlas sections, is available to premium members on Kenhub.com.

Q & A

What is the primary focus of the tutorial presented by Nicole from Kenhub?

The tutorial primarily focuses on the nerves of the nasal cavity.

What are the three main functions of the nasal cavity?

The three main functions of the nasal cavity are to warm, humidify, and filter air as it enters the nostrils; to hold the olfactory epithelium, which is responsible for the sense of smell; and to produce mucus that helps filter the air.

How does the nasal cavity warm and filter the air?

The nasal cavity warms and filters the air due to the hair and mucous lining of the internal walls, which remove allergens before the air passes into the lungs.

What is the role of the olfactory epithelium in the nasal cavity?

The olfactory epithelium is the organ that contains the receptors for the sense of smell.

What are the two paired cavities found on either side of the nasal septum?

The two paired cavities found on either side of the nasal septum are the nasal cavities.

What are the nasal cavities separated from each other by?

The nasal cavities are separated from each other by a nasal septum.

What is the composition of the nasal septum?

The nasal septum is composed of septal cartilage and two bones of the skull, the vomer and the ethmoid bone.

How does the nasal cavity contribute to the production of mucus?

The nasal cavity contributes to the production of mucus, which helps filter the air entering the nose.

What is the term for the openings at the beginning of the nasal cavity?

The openings at the beginning of the nasal cavity are called the nares or nostrils.

What is the term for the area that separates the nose from the mouth?

The area that separates the nose from the mouth is called the hard palate.
