The tissue shown in the image is which of the following?

• A. Skin
• B. Liver
• C. Muscle
• D. Brain

Answer: (A)

Recognize tissue by its structure and organization. The image shows a keratinized, stratified squamous epithelial layer on top of a connective tissue region that contains structures such as hair follicles or glands. This layered epidermis with a dermal underlying matrix is characteristic of skin. In contrast, liver would present cords of polygonal hepatocytes around a central vein with sinusoids; muscle would show long, parallel fibers with visible striations; brain would reveal neuron cell bodies with processes and a defined gray/white matter arrangement. The presence of a thick, keratinized epithelium atop a supporting dermal layer points to skin.
