The albino laboratory rat with its red eyes and white fur is an iconic model organism for scientific research in a variety of fields. Laboratory rats or lab rats are strains of the rat subspecies Rattus norvegicus domestica (Domestic Norwegian rat) which are bred and kept for scientific research.
Pictomicrograph shows the posteromedial barrel subfield in layer IV of the rat somatosensory cortex. Barrels in the PMBSF are particularly large and distinct. The tissue in the image has been stained with cytochrome oxidase and is 50μm thick. The barrel field, like many regions of cortex, is organised into a topographic map. In the case of the ...
A closeup of a rat tail. The characteristic long tail of most rodents is a feature that has been extensively studied in various rat species models, which suggest three primary functions of this structure: thermoregulation, [13] minor proprioception, and a nocifensive-mediated degloving response.

A prosection is the dissection of a cadaver (human or animal) or part of a cadaver by an experienced anatomist in order to demonstrate for students anatomic structure. [1] In a dissection, students learn by doing; in a prosection, students learn by either observing a dissection being performed by an experienced anatomist or examining a specimen that has already been dissected by an experienced ...
The brown rat (Rattus norvegicus), also known as the common rat, street rat, sewer rat, wharf rat, Hanover rat, Norway rat and Norwegian rat, is a widespread species of common rat. One of the largest muroids, it is a brown or grey rodent with a body length of up to 28 cm (11 in) long, and a tail slightly shorter than that. It weighs between 140 ...
Most health profession schools, such as medical, physician assistant, and dental schools, require that students complete a practical (dissection) course in gross human anatomy. Such courses aim to educate students in advanced funadmental human anatomy and seek to establish anatomical landmarks used to aid medical diagnosis .
A key principle in the dissection of human cadavers (sometimes called androtomy) is the prevention of human disease to the dissector.Prevention of transmission includes the wearing of protective gear, ensuring the environment is clean, dissection technique [2] and pre-dissection tests to specimens for the presence of HIV and hepatitis viruses.
