Answer:

“Clearly, some testing and research is done in dogs for historical reasons [existence of benchmark data] rather than because they are the best models

Explanation:

It is unconscionable that dogs, the most popular companion animals in the country, are used as research subjects in laboratories, but that is the tragic truth. United States Department of Agriculture (USDA) reports show that tens of thousands of dogs are used in research, testing, teaching, or experimentation in the U.S. every year by research facilities, including hospitals, schools, diagnostic laboratories and private firms in the pharmaceutical and biotechnology industries.

Although the number of dogs used in research has declined by 72% since their peak use in 1979, the most current USDA statistics show that 59,401 dogs were used for “research, testing, teaching, or experimentation” in 2018, although the exact purposes for which these dogs were used remain unclear.

Likurg_2 [28]

Answer:

Mechanoreceptors would be activated

Explanation:

The skin is a complex organ that is found covering the entire surface of the human body. The mechanoreceptors are responsible for the sense of touch, that is, the capture of pressure on the skin. They are the Meissner corpuscles and the Vater-Pacini corpuscles, which are made up of nerve endings and connective tissue, in other words, they are receptors that are stimulated by muscle contraction and pressure on the joint elements. It allows to know the position of the body and the degree of contraction of the muscles.

Anatomy of the liver: an outline with three levels of complexity--a further step towards tailored territorial liver resections.

QveST [7]

Depending on the purpose for which the description is needed, there are three various levels of complexity at which the vascular architecture of the liver might be described:

The first level, known as the conventional level, is equivalent to Couinaud's classic 8-segment scheme and serves as a common language for doctors from other disciplines to define the location of localized hepatic lesions.
The true branching of the hepatic veins and the main portal pedicles is taken into consideration in the second, surgical level, which will be used for anatomical liver resections and transplantations. Modern surgical and radiological procedures may fully exploit this anatomy, but doing so involves acknowledging that the Couinaud scheme is oversimplified and examining the vascular architecture objectively.
The third degree of complexity, known as the academic level, is focused on the anatomist and the requirement to provide a systematization that clarifies the apparent conflicts between anatomical literature, radiological imaging, and surgical practice.
