Medical Science and Health Quiz

The pituitary gland is called the 'master gland' because it controls other endocrine glands through hormones like TSH, ACTH, FSH, and LH. The pancreas regulates blood sugar, thyroid controls metabolism, and spleen is part of the immune system.

Newborn infants have approximately 300 bones, which fuse together during growth to form the 206 bones in an adult human skeleton. This fusion occurs in areas like the skull, spine, and pelvis.

Vitamin A is essential for healthy vision, particularly for night vision and maintaining the cornea. Deficiency can cause night blindness and xerophthalmia. Vitamin B is for metabolism, C for immunity, D for calcium absorption.

A normal adult resting heart rate is approximately 60-100 beats per minute, with 72 bpm being a commonly cited average. Option B (70) falls within this normal range.

AB blood group individuals lack anti-A and anti-B antibodies, so they can receive blood from any group (A, B, AB, or O) without antibody-mediated rejection. They are called universal recipients.

Malaria primarily affects red blood cells, but the spleen becomes enlarged (splenomegaly) as it works to filter and destroy the infected RBCs. The malaria parasite (Plasmodium) replicates in red blood cells, causing their destruction.

Small pox is caused by the Variola virus, making it the only viral disease in this list. Tuberculosis is caused by bacteria (Mycobacterium tuberculosis), malaria by a protozoan parasite (Plasmodium), and cholera by bacteria (Vibrio cholerae).

The medulla oblongata is the lowest part of the brainstem, connecting the brain to the spinal cord. It controls vital autonomic functions like breathing, heart rate, and blood pressure.

Myopia (nearsightedness) is a refractive error of the eye where distant objects appear blurry. It occurs when the eyeball is too long or the cornea is too curved, causing light to focus in front of the retina.

Leukemia is a cancer of the body's blood-forming tissues, including the bone marrow and the lymphatic system. It involves the overproduction of abnormal white blood cells that crowd out healthy blood cells.

Trachoma is an infectious eye disease caused by the bacterium Chlamydia trachomatis. It is one of the leading causes of preventable blindness worldwide and affects the conjunctiva and cornea.

Lockjaw (trismus) is a characteristic symptom of tetanus, caused by the toxin Clostridium tetani. This toxin causes severe muscle spasms and stiffness, particularly in the jaw muscles (hence 'lockjaw') and neck.

Poliomyelitis (polio) is transmitted through the fecal-oral route, not through monkeys. The other pairs are correct: plague is associated with rats (fleas from rats), rabies with dogs, and tapeworm infections can come from undercooked pork.

Rickets is a bone disease caused by vitamin D deficiency, calcium deficiency, or phosphate deficiency in children. It leads to soft and weak bones, skeletal deformities, and impaired growth.

The pulmonary artery carries deoxygenated blood from the heart to the lungs for oxygenation - this is why it's called 'impure blood.' The pulmonary vein does the opposite, carrying oxygenated blood back to the heart.

Normal human body temperature is approximately 36.9°C (98.6°F). This is the average oral temperature, though it can vary slightly based on time of day, age, and measurement method.

Oracle Database Lite was indeed Oracle's lightweight database solution designed specifically for mobile devices and embedded systems. It provided a smaller footprint version of Oracle's enterprise database for resource-constrained environments. The other options (Mobile, Micro, Mini) are not actual Oracle product names for mobile databases.

AmberPoint was a Service Oriented Architecture (SOA) management company that Oracle acquired in 2010 to strengthen its middleware and SOA governance capabilities. TIBCO, iWAY Software, and Systinet were independent companies at that time (TIBCO and Systinet were later acquired by other companies).
