Children have 20 milk teeth (primary teeth) in their initial years. These begin appearing around 6 months of age and are usually complete by age 2-3. Adults have 32 permanent teeth. The milk teeth include 8 incisors, 4 canines, and 8 molars, which are later replaced by permanent teeth starting around age 6.

Yawning is an involuntary physiological response that occurs when oxygen levels in the brain drop and carbon dioxide levels rise. The deep inhalation during a yawn increases oxygen intake while the exhalation helps expel more carbon dioxide, helping restore proper gas balance in the blood and brain. Eating, drinking water, or running do not directly address this specific physiological need for gas exchange in the brain.

Ragi (finger millet) is exceptionally rich in calcium, containing approximately 344mg per 100g, while brown rice has only about 33mg per 100g. This means ragi has roughly 10 times more calcium content than brown rice, making it a superior source for bone health and calcium deficiency prevention.

Soaked almonds are beneficial for brain and nervous system health due to their high vitamin E content, healthy fats, and antioxidants. Soaking removes phytic acid and enzyme inhibitors, improving nutrient absorption. Almonds contain riboflavin and L-carnitine which support cognitive function and neurological health.

One cup (240ml) of cow milk contains approximately 300mg of calcium, which is about 29-30% of the recommended daily intake of 1000mg for adults. This makes milk a significant calcium source for bone health. The calcium in milk is also highly bioavailable and easily absorbed by the body.

Excessive carrot consumption can cause carotenosis (also called carotenemia), a harmless condition where excess beta-carotene accumulates in the skin, causing orange-yellow discoloration particularly on palms, soles, and face. It reverses when carrot intake is reduced. This is not a disease but a temporary skin color change.

Cabbage is indeed a good source of vitamin C, with raw cabbage providing about 36 mg per cup (approximately 60% of daily value). Vitamin C supports immune function and collagen synthesis. The False option is incorrect because cabbage's vitamin C content is well-documented in nutrition science.

Aloe vera juice has been used traditionally and commercially for digestive relief. It contains compounds that may help soothe digestive irritation and is consumed as a health beverage. While excessive consumption can have side effects, its use for digestive issues is well-established.

Soya products are complete protein sources and are widely used as meat and dairy substitutes in vegetarian and vegan diets. Tofu, tempeh, and soya milk can replace animal-based foods nutritionally. The False option is incorrect because soya's versatility as a protein alternative is well-established.

Bhringraj (Eclipta alba) is indeed a well-known herb in Ayurvedic medicine, traditionally used to promote hair health and darken hair color. It is a common ingredient in hair oils and treatments in India. The False option is incorrect because Bhringraj's reputation for hair darkening is well-established in Indian traditional medicine.

Spinach is high in oxalates, compounds that can bind with calcium in the urinary tract to form kidney stones. People prone to calcium oxalate stones are often advised to limit high-oxalate foods like spinach. However, spinach also has nutritional benefits, so the risk applies primarily to susceptible individuals.

HIV stands for Human Immunodeficiency Virus, a virus that attacks the body's immune system and can lead to AIDS (Acquired Immunodeficiency Syndrome). The name correctly describes it as a virus that causes immunodeficiency in humans.

AIDS stands for Acquired Immunodeficiency Syndrome, the late stage of HIV infection. The term describes it as an acquired (not inherited) condition that causes deficiency in the immune system, leading to a syndrome of opportunistic infections.

MI stands for Myocardial Infarction, the medical term for heart attack. 'Myocardial' refers to the heart muscle (myocardium), and 'Infarction' means tissue death due to lack of blood supply. Note: the correct spelling is 'Infarction' not 'Infraction'.

Hypertension is the medical term for high blood pressure - a condition where blood pressure in the arteries is persistently elevated. It's a major risk factor for heart disease, stroke, and other cardiovascular problems. Note: the question has 'Hyprtension' - a typo.

Meningitis is the inflammation of the protective membranes covering the brain and spinal cord, not a respiratory condition. Asthma affects the airways, ARDS is a severe lung condition, and Pneumonia is an infection of the lungs - all three are respiratory diseases.

Oxytocin is produced in the hypothalamus and released by the posterior pituitary gland, not the anterior pituitary. The anterior pituitary secretes hormones like Prolactin, FSH, LH, TSH, ACTH, and Growth Hormone. This makes Oxytocin the correct answer to what is NOT secreted by the anterior pituitary.

AFMC stands for Armed Forces Medical College, a prestigious medical institution in Pune. The other options are fictional expansions. This college trains medical professionals for the Indian Armed Forces.
