It guides the reader through normal mouse anatomy and histology using direct comparison to the human. The basic structure and function of a nerve cell (neuron) and what the differences are between axons and dendrites. In the peripheral nervous system axons are bundled together in structures called nerves. Each nerve process is surrounded by a later of connective tissue called the endoneurium, which looks like a dark purple line around each process in this nerve. Skin (Am J Surg Pathol 2017;41:1542, Mills: Histology for Pathologists, 5th Edition, 2019) Thin skin covering Stratified squamous keratinized epithelium Loosely connected to deeper parts of the organ Mucosa Stratified squamous epithelium Up to 10 cell thickness Nonkeratinizing at glans penis, keratinized after circumcision Lamina propria As in the peripheral nervous system each Schwann cell myelinates only one axon, the discontinuous appearance of the axon labeled 5 in a Schwann cell is probably due to its curvature around the nucleus.
