Answer:

c) Negri bodies are a diagnostic sign of Rabies virus infection.

Explanation:

Rabies is an infection caused by rabies virus which affects the neurons and causes inflammation of the brain. It is a deadly disease and many animals are carriers of this disease like dogs, cats, raccoons, wolf, bats, fox, etc.

It is diagnosed by the presence of Negri bodies in the cytoplasm of nerve cells. Negri bodies are inclusions that are round or oval shapes having a size between 0.25 to 27 μm. Negri bodies can be frequently diagnosed in Purkinje cells of the cerebellum and pyramidal cells of Ammon’s horn.

Apart from these cells, they can be found in various ganglia, neurons of the tongue and other organs. So the correct answer is c.

Answer:

a vestigial structure

Explanation:

Vestigial structures are a rudimentary (or even functionless) version of a body part, but they have important functions in a closely correlated or evolutionarily close species, an example of which is the presence of eyes in fish of the genus Astyanax. The existence of these vestigial structures is strong evidence that evolution occurs in organisms, since this structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species.

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.
