cutting a sample perpendicular to its length for examination
Transverse sectioning refers to cutting a sample, such as a hair strand or tissue, perpendicular to its length. This method allows for the examination of the internal structure and layers of the sample, providing detailed insights into its composition and any potential abnormalities. For instance, in hair analysis, transverse sectioning can reveal the condition of the hair cortex and medulla, which are crucial for diagnosing issues like alopecia.
