Nose and Nasal Cavity

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...

Saline Lavage for Sampling of the Canine Nasal Immune Microenvironment
0 Views •
2024
Saline nasal lavage can be used to sample the canine nasal immune microenvironment. Because the approach is relatively non-invasive and does not disrupt the nasal tissues, it can be performed serially. Cells and proteins collected from the nasal lavage technique can be processed for various laboratory analyses.

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...

We describe here a method for biopsying olfactory mucosa from rat and human nasal cavities. These biopsies can be used for either identifying molecular anomalies in brain diseases or isolating multipotent adult stem cells that can be utilized for cell transplantation in animal models of brain trauma/disease.
FAQs
Turbinates create a highly expanded internal surface within the canine nasal cavity, while the nasal septum separates the passage into channels. This arrangement increases contact between incoming air and the cavity lining, supporting the conditioning of air before it continues through the respiratory system. Changes affecting these structures can therefore alter normal airflow and complicate evaluation of upper respiratory disease in dogs.
Mucociliary transport provides a clearance step after inhaled material becomes trapped on the nasal lining. It moves that material away from the air passages, helping the cavity contribute to respiratory defense rather than merely serving as an entry route for air. In veterinary medicine, altered clearance is relevant when investigating nasal infection or persistent inflammation.
Olfactory epithelium gives the nasal cavity a sensory role distinct from its respiratory functions because it detects odor molecules. This distinction helps explain why examination of nasal disease can matter for both breathing-related signs and olfactory function. It is especially relevant when interpreting abnormalities that affect specialized nasal tissues in dogs.
Veterinary assessment can begin with physical examination and then incorporate imaging, rhinoscopy, or biopsy when additional evaluation is needed. The overview does not prescribe one fixed sequence; instead, these modalities form a clinical toolkit for investigating abnormalities of the nasal cavity and improving diagnosis in dogs with upper respiratory disease.
The same anatomical knowledge supports investigation of several problems, including rhinitis, infection, foreign bodies, trauma, and nasal tumors. These conditions may affect the nasal passage in different ways, so clinicians use the cavity’s structure and functions to frame the examination and select evaluations that can support diagnosis.
Assessment findings can improve diagnosis and inform treatment of upper respiratory disease in dogs. This makes the canine nasal cavity relevant beyond anatomy lessons: its structural arrangement and specialized lining provide clinical context for interpreting abnormalities detected during examination, imaging, rhinoscopy, or biopsy. The result is a more informed approach to veterinary case evaluation.
