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 ...
Biological specimens in an elementary school science lab. A biological specimen (also called a biospecimen) is a biological laboratory specimen held by a biorepository for research. Such a specimen would be taken by sampling so as to be representative of any other specimen taken from the source of the specimen. When biological specimens are ...
Medical schools have implemented on-screen anatomical lessons and tutorials to teach students surgical procedures. The use of technological visual aids accompanied with gross dissection have been shown to be more effective than learning via one modality alone. [6] Online and physically made flashcards and quizzes [7] have been long used.
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.

A laboratory specimen is sometimes a biological specimen of a medical patient's tissue, fluids, or other samples used for laboratory analysis to assist in differential diagnosis or staging of a disease process. These specimens are often the most reliable method of diagnosis, depending on the ailment.
In 1830 and 1833, they allowed unclaimed bodies to be used for dissection. [6] Laws in almost every state were subsequently passed and grave-robbing was essentially eradicated. Although dissection became increasingly accepted throughout the years, it was still very much disapproved by the American public in the beginning of the 20th century.
The fetal pig's urogenital system is similar to the adult pig's system with the exception of the reproductive organs. The fetal pig urinary tract is relatively developed and easy to locate during dissection. The kidneys are located behind the abdominal organs and are partially embedded into the dorsal body wall by the spine.
The stereo, stereoscopic or dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it. The instrument uses two separate optical paths with two objectives and eyepieces to provide slightly ...
