During the Spring semester, the Microanatomy and Histology class has learned techniques of tissue collection, histological processing and staining, microscopic observation, and cellular evaluation and analysis. Here, we present a product of this work in a gallery of nine student project posters, each exploring a selected mouse (Mus musculus) tissue or organs. For each project, tissue slides were processed using two complementary staining techniques to visualize a broader range of cellular structures and gain a better understand of the relationship between morphological structures and the regulation of physiological functions. To that end, each student’s poster delves into tissue-specific cell types and architectures to provide an overview of how those cells’ function to support the organism as a whole. We invite you to take this “Journey to the Center of the Mouse”, to talk with the students who did this work, and to gain a greater understanding of multicellular organism complexity.My tissue consists of the Footpad of the Mus Musculus.In the mouse, the footpad is the only tissue with eccrine sweat glands, the keratinized, stratified efferent duct from these glands coil through the thick epidermis of the mouse footpad. These sweat glands are thought to provide tactile sensitivity. Which is an increased sensitivity to touch that makes the mouse feel peculiar. The epithelium that the mouse’s footpad contains is the stratified squamous epithelium, in a human the stratum spinosum is composed of multiple layers of keratinocytes; however, in mouse’s epidermis the stratum spinosum is composed of typically one cell layer in its truncal skin. In the Hypodermis of a human, vertical tethers of dense connective tissue extend upward into the dermis to help anchor the hypodermis with the dermis, while in a mouse the hypodermis consists of one more layer known as “brown fat”. Additionally, the mouse’s feet are always on ground at all times stepping/going through anything, this knowledge lets us know that the footpad is an important route of vaccination in mouse’s. Given this information you are able to test the inflammation and swelling of the injection site for any research that is being done to be best ability.
