Which procedure involves removing tissue from a muscle for microscopic analysis?

• A. Palpation
• B. Otoscopy
• C. Muscle biopsy
• D. Pap smear

Answer: (C)

Tissue sampling from muscle for microscopic analysis is performed by a muscle biopsy. By removing a small piece of muscle, pathologists can examine the tissue under a microscope to detect inflammation, degeneration, fiber changes, or other abnormalities that explain weakness or disease. Palpation involves feeling with the hands and does not collect tissue. Otoscopy is used to inspect the ear canal and tympanic membrane, not sample tissue. A pap smear collects cells from the cervix for cytological analysis, not muscle tissue.
