Medical Term Quiz Questions Part - 10

Explanation
Urobilinogen is a pigment found in faecal matter. It is a byproduct of the breakdown of bilirubin, a yellow pigment that is formed when red blood cells are broken down in the liver. Urobilinogen gives feces its characteristic brown color. Titanium oxide is not found in faecal matter, as it is a white pigment commonly used in paints and cosmetics. Creatinine is a waste product produced by muscles and is excreted in urine, not feces. Keratin is a protein found in hair, nails, and skin, and is not a pigment found in faecal matter.

Explanation
Glycogenated epithelial cells can be used to characterize vaginal secretions. These cells are found in the vaginal epithelium and produce glycogen, which serves as a food source for Lactobacillus bacteria. The presence of glycogenated epithelial cells indicates a healthy vaginal environment with a sufficient population of Lactobacillus, which helps maintain the acidic pH and prevent the growth of harmful bacteria. Therefore, the presence of glycogenated epithelial cells is a positive indicator of vaginal health.

Explanation
The precipitin test is performed to determine the species of a particular sample. This test involves the reaction between an antigen and its corresponding antibody, which produces a visible precipitate. By comparing the precipitate formed with known samples, scientists can identify the species of the unknown sample. This is particularly useful in forensic investigations, where it can help determine the source of biological materials found at a crime scene.

Explanation
The correct answer is "Alternate light source." Polilight works by using an alternate light source, which is a specialized light that can reveal hidden evidence such as fingerprints, bodily fluids, or trace evidence. This alternate light source emits different wavelengths of light, allowing investigators to see things that may not be visible under normal lighting conditions. It is a valuable tool in forensic investigations as it helps in identifying and collecting evidence at crime scenes.

Explanation
The grazing angle in case of oblique light examination of documents pertains to 10-15 degrees. This means that when examining documents with oblique light, the light source should be positioned at an angle of 10-15 degrees from the surface of the document. This angle helps to enhance the visibility of any surface irregularities, such as indentations or alterations, on the document. By using oblique light at this specific angle, it becomes easier to detect any hidden or tampered information on the document.

Explanation
In a case of hanging, if the knot is situated at the occipital region, it is referred to as "Typical". This means that the knot is located at the back of the head, specifically the occipital region. This term is used to describe a common or expected location for the knot in cases of hanging.

Explanation
Tracing is the most suitable method for preservation of surface footprints because it involves creating an exact replica of the footprint by drawing or outlining its shape and details. This method allows for accurate preservation without altering or damaging the original footprint. Wax cast and plaster of paris cast, on the other hand, involve creating physical casts of the footprint, which may not always capture all the intricate details and can potentially damage the original surface. Therefore, tracing is the preferred method for preserving surface footprints.

Explanation
The first permanent tooth to erupt is the Molar-I. This is because the molars are located at the back of the mouth and typically erupt before the other permanent teeth. The eruption of the first permanent molar usually occurs around the age of 6 or 7, which is earlier than the eruption of the other permanent teeth. Therefore, Molar-I is the correct answer.

Explanation
Taurodontism is a dental anomaly characterized by an elongated pulp chamber in the teeth. It is more commonly found among Mongoloids, which include populations from East Asia, Southeast Asia, and the Arctic. This dental feature is less frequently observed among Caucasians, Indians, and Negroids. Therefore, the correct answer is Mongoloids.

Explanation
Asbestosis is a lung disease caused by inhaling asbestos fibers. These fibers can cause scarring and inflammation in the lungs, leading to breathing difficulties and a higher risk of developing lung cancer. Symptoms of asbestosis include shortness of breath, persistent cough, chest pain, and fatigue. The correct answer, Asbestosis, is a specific condition related to the inhalation of asbestos fibers, which distinguishes it from the other options listed (Stannosis, Berylliosis, and Silicosis).
