Testicle, cross-section, microscope slideThis microslide shows a cross-section of testicular tissue, showing the cells and structures involved in sperm formation. The slide is stained with red and blue contrast dyes, making it easier to distinguish the different cell types and tissue layers. The nuclei of the cells appear as darker structures, while the cytoplasm and cell membranes form the surrounding shapes. The slide is designed to closely resemble illustrations in biology textbooks, making it easy to recognize the most important details, even without a medical background.
