Are you interested in exploring mouse anatomy, without having to break out the dissection tools? Well, the people at MRPath allow you to do just that, providing free, online atlases of MRI images of the entire mouse. The older Visible Mouse Atlas is a helpful tool to learn mouse anatomy, as colored labels corresponding to various anatomical features can be toggled on or off. The labels are also organized by system, so one can focus on the features of the nervous system, for example. The newer Mouse Strain Phenotype Database also consists of 3-D anatomical constructs of MRI images, but it showcases both male and female mice of a variety of strains. Whether you’re partial to c57’s or Balb/c’s, you can explore strain-specific anatomy. The only downside to this new database is that there are not yet anatomical labels.
