    Area of Science:

    • Toxicology
    • Anatomy
    • Histology

    Background:

    • The rat larynx is increasingly recognized for its role in evaluating inhaled irritant toxicity.
    • Understanding laryngeal structure is key to interpreting toxicological responses.

    Purpose of the Study:

    • To elucidate the detailed structure of the rat larynx.
    • To characterize the distribution of epithelial types within the rat larynx.

    Main Methods:

    • Serial sectioning of rat larynges.
    • Scanning electron microscopy (SEM) for high-resolution surface imaging.

    Main Results:

    • Detailed cartilage patterns of the rat larynx were identified.
    • Two specialized epithelia (stratified squamous and ciliated pseudostratified columnar) and an unspecialized non-ciliated columnar epithelium were mapped.
    • Epithelial types varied significantly over short distances.

    Conclusions:

    • The rat larynx possesses distinct structural features relevant to inhaled irritant studies.
    • Consistent anatomical orientation is critical for comparative laryngeal studies.
