Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA This video provides an overview of sinus, nose, and throat examinations. The demonstration begins with a brief overview of the anatomy of the region. The upper third of the nose is bony, and the bottom two-thirds are cartilaginous. Air entering the nares passes through the nasal vestibules and into the narrow passageway between the nasal septum...

A rapid method for volatile compound analysis in fruit is described. The volatile compounds present in the headspace of a homogenate of the sample are rapidly separated and detected with ultra-fast gas chromatography (GC) coupled with a surface acoustic wave (SAW) sensor. A procedure for data handling and analysis is also discussed.

Nose and Nasal Cavity

2025
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Visualizing Onion and Human Cells ExpandIn this experiment you will prepare different types of cells from a plant and animal, onion and human respectively, and then visualize them under a microscope. HYPOTHESES: The experimental hypothesis is that the cells will appear different in overall shape and membrane structure, but there will be some shared similar structures, like nuclei, in both cells. The null hypothesis of the experiment is that there will be no difference in structure between the...

The inhalation unit described herein can generate, sample for characterization, and uniformly deposit a drug aerosol in the lungs of rodents. This enables the pre-clinical determination of the efficacy and safety of drug doses deposited in the lungs; key data enabling clinical inhaled drug development.
FAQs
As air moves beyond the nasal vestibule, it passes across the turbinates and mucosal surfaces. This arrangement exposes inhaled air to tissues that help warm and humidify it before it continues through the upper airway. Clinically, these relationships help explain why changes affecting internal nasal anatomy can influence comfortable airflow and nasal function.
Nasal hairs and mucus help trap particles before they travel farther into the airway. The rich blood supply contributes to warming inhaled air, while the mucosal surfaces support humidification. Together, these features show that nasal protection depends on coordinated structural and tissue functions rather than on the nostrils alone.
The olfactory epithelium contains sensory receptors that detect odor molecules. Its location within the nasal anatomy connects the passage of inhaled air with smell perception, so clinical evaluation of smell disorders requires attention to both sensory structures and the surrounding nasal organization. This relationship also distinguishes olfaction from the nose’s airway-protection functions.
Nasal obstruction and inflammation can be considered in relation to the connected external and internal features through which air normally passes. Examining these relationships helps clinicians assess whether symptoms may involve the vestibule, turbinates, mucosal surfaces, or the septal region. The same anatomical framework also supports assessment after trauma or with congenital variation.
Physical examination allows clinicians to relate visible or accessible nasal features to the organization of the upper airway. It can support assessment of obstruction, inflammation, trauma, congenital variation, and disorders of smell. Rather than considering each symptom in isolation, clinicians use the structural relationships to guide what requires closer evaluation or additional investigation.
Understanding the arrangement of nasal structures helps guide both imaging and procedures. Imaging can support clinical assessment when structural relationships require further evaluation, while procedures such as septal or sinus surgery depend on anatomical understanding. In practice, this context helps clinicians connect a patient’s findings with the structures involved and plan an appropriate intervention.
