The sunbmaxillary is bean shaped and located under the bigger parotid gland. The submandibular gland lies near the jaw line. Glottis -The opening

1974). The study of digestion involved developing "fistulas" through which secretions from salivary glands‚ stomach‚ the pancreas‚ and small intestine could be collected (Girogian‚ 1974). His technique was truly unique in that he did not cut the nerve supply nor contaminate the secretions with food. The most famous and well-known experiment of Pavlov is that he ’conditioned ’ dogs to start a salivary response to the sound of a bell. He began by measuring the amount of salivation in response to

Polio was once a leading cause of disability in the United States. Since the introduction of the vaccine in 1955‚ the disease has been eradicated in the United States. Because other developing countries still have polio‚ there is still a possibility that the disease can be spread. As a result of this‚ youth still need to be vaccinated at two‚ four‚ six-eighteen months‚ and a booster dose at four-six years old. Measles‚ Mumps and Rubella or (MMR) are all viral diseases that can be extremely serious

A 5 year old girl Jenny has presented to the Emergency Department with her mother‚ she is suffering from a variety of symptoms including wheezing and vomiting‚ a dry mouth‚ and a temperature of 39.7 degrees Celsius. Vomiting is when the person is excreting all food from there stomach via the mouth using forces from the oesophagus and stomach (Hockenberry & Wilson‚ 2007). The rationale for choosing this symptom is that vomiting is a clear sign that the body is trying to get rid of a pathogen‚ with

Salivary gland cancer occurs in the glands that produce saliva‚ located in front of and just below each ear (parotid glands)‚ under the tongue in the floor of the mouth (sublingual glands) and below the jawbone (submandibular glands).

Enzymes An enzyme is a protein used to speed up the rate of a chemical reaction. Because they regulate the rate of chemical reactions‚ they are also called catalysts. There are many‚ many different types of enzymes‚ because for each chemical reaction that occurs‚ an enzyme specific to that reaction must be made. To act on a substrate‚ an enzyme must contain an active site. The active site is the area on the enzyme that allows the substrate and enzyme to fit together. The amino acids that are present

Concentarion ENZYME LAB Introduction- Enzymes are proteins that speed up the rate of reactions in living things. In this lab‚ we will perform four experiments exploring the way enzymes work. PART A: pH SPECIFICITY Every enzyme has a specific pH at which it works best. In this section‚ you will determine which pH is best for the enzyme‚ catalase. Living tissues produce the enzyme catalase‚ which is able to break down hydrogen peroxide into oxygen gas and water. The reaction is

The Identification of Bacillus Badius [pic] Hannah Melanchuk Dr. Robert Suran May 1 2013 Microbiology Abstract Over a three week time span I was able to successfully identify an unknown microorganism by combining the results of several tests. The first test was the Gram stain test which showed the microorganism was Gram positive and rod shaped. Using an Unknown Identification Flowchart‚ I proceeded to inoculate a Starch plate. In week 2‚ I

However‚ many various inhibitors studied not only blocked the Glucansucrase‚ but also the digestive enzyme amylase in our saliva‚ which is needed to degrade starch. Therefore‚ lots of researches need to be proved
