In pathology, the sectioning or dividing of tissue samples using specialized cutting techniques to prepare them for microscopic examination in beautiful or precise ways.
From Latin 'callis' (a way or path) + 'section' (the act of cutting). This is a rare technical term in medical histology, blending Greek/Latin roots with modern scientific methodology.
Pathologists use callisection techniques under microscopes where even a fraction-of-a-millimeter difference in a tissue slice can reveal or hide crucial diagnostic information—it's a surgical art form that requires both technical precision and interpretive skill.
