Over 100 million animals are burned‚ crippled‚ poisoned and abused in U.S. labs every year. 92 percent of experimental drugs that are safe and effective in animals fail in human clinical trials because they are too dangerous or don’t work. Labs that use mice‚ rats‚ birds‚ reptiles and amphibians are exempted from the minimal protections under the Animal Welfare Act (AWA). Up to 90 percent of animals used in U.S. labs aren’t counted in the official statistics of animals tested. The

ware‚ which includes a large variety of tubes and flasks‚ is essential to any functioning biological lab. Test tubes‚ culture tubes and tissue culture flasks all fall under this category. Scientists use culture tubes and flasks to grow bacteria and human cells. Scientists value the completely sterile nature of these tubes; companies manufacture flasks and tubes in sterile conditions‚ so scientists know that anything they grow in those containers will not be contaminated.

“We cannot know the consequences of suppressing a child’s spontaneity when he is just beginning to be active. We may even suffocate life itself. That humanity which is revealed in all its intellectual splendor during the sweet and tender age of childhood should be respected with a kind of religious veneration. It is like the sun which appears at dawn or a flower just beginning to bloom. Education cannot be effective unless it helps a child to open up himself to life.” -- Maria Montessori

Practical 12: Digestion in Humans Aim: To distinguish between 5 liquids to come to a conclusion from which region of the alimentary canal it was extracted from. Hypothesis In this practical‚ we have been given 5 unknown solutions hence it is not possible for us without any logical analysis to come up with a conclusion regarding the positioning along the alimentary canal. We cannot come up with a proper answer or predict results without running through the tests. I though can base my

Pathology laboratories study disease. Diseases are mainly diagnosed through analysis of tissue‚ body fluid and cell samples. Pathology laboratories can also study the predicted or actual progression of particular diseases. Pathology is a field of general inquiry and research so addresses four components of disease. These components are cause‚ mechanisms of development‚ structural alterations of cells and the consequences of the changes. If a hospital sends off a sample to a pathology laboratory‚ when

Optic nerve sheath diameter (ONSD) The anatomy of the optic nerve sheath : The intraorbital section of the optic nerve extends from the globe‚ where it inserts medially‚ to the optic canal located in the lesser wing of the sphenoid bone. It is encased by a meningeal sheath consisting of dura mater‚ arachnoid mater and pia mater. Cerebrospinal fluid is contained in the trabeculated subarachnoid space and is continuously and slowly filtered. As a result the optic nerve sheath is in direct
