Our noses and ears are unique compared to the rest of our bodies because they're composed of soft tissue enveloped in cartilage. And it's this soft tissue that keeps growing throughout our entire lives.
Answer: The eyeball is the only organism which does not grow from birth. It is fully grown when you are born.
While the rest of our body shrinks as we get older, our noses, earlobes and ear muscles keep getting bigger. That's because they're made mostly of cartilage cells, which divide more as we age.
Answer and Explanation: The parts of the human body that never stop growing are cartilage appendages, such as the ears and nose.
Explanation: The growth of most structures(muscles, bones etc...) of human body stops after adolescence. But here is one special structure called cartilage that continue to grow till death.
Teeth are the ONLY body part that cannot repair themselves. Repairing means either regrowing what was lost or replacing it with scar tissue. Our teeth cannot do that. Our brain for example will not regrow damaged brain cells but can repair an area by laying down other scar-type tissue .
Although some patients who have a diseased portion of their liver removed are unable to regrow the tissue and end up needing a transplant.
Vestigial organs are parts of the body that once had a function but are now more-or-less useless. Probably the most famous example is … the appendix, though it is now an open question whether the appendix is really vestigial.
You'll be surprised as to how much you could lose and still live. You can still have a fairly normal life without one of your lungs, a kidney, your spleen, appendix, gall bladder, adenoids, tonsils, plus some of your lymph nodes, the fibula bones from each leg and six of your ribs.
Bones stop growing after puberty. But cartilage, the plastic-like substance in our ears and noses, continues to grow. Not only does cartilage grow, but earlobes also elongate from gravity, which can make ears look even larger.
This study supports the view that as people age, their ears get larger, particularly the ear circumference, which increases on average 0.51 mm per year. This enlargement is likely associated with aging changes of collagen.
We don't simply keep growing
The skeleton has finished growing at this point and the growth plates between bones are fused closed. Once this happens, there's no way for bones to continue to grow, even the small bones in the ears and the nose. There are two exceptions to this: the pelvis and the skull.
You might be surprised to know that your face is not actually the part of your body that ages the fastest. It is, in fact, your breasts. A study, published by the journal Genome Biology has found that breast tissue is the part of the body that's most sensitive to the affects of ageing.
Neck. Neck is the first part to show ageing. This is because the skin on your neck is thinner and more delicate than the rest of your body. The sagging on your chin and neck may appear sooner than you expected.
Which Part of the Body Heals the Fastest? Muscles and tendons generally heal the fastest. These parts of the body recover more quickly thanks to an ample blood supply. The circulatory system provides muscles with plenty of nutrients and oxygen needed for healing.
Glute Muscles
Perhaps the most neglected muscle group in the body, the Glutes are also one of the most important muscle groups for proper biomechanics and optimal sports performance. They're also connected to your spine, so weak Glutes muscles can lead to back pain and injury.
There's a good reason you've never heard of the fabella, a tiny bone embedded in the tendon of the knee. The bone, whose name means “little bean,” doesn't seem to serve any purpose. Not everyone has one, and people do just fine without it.
The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.
The brain is the only organ in the human body that cannot be transplanted. The brain cannot be transplanted because the brain's nerve tissue does not heal after transplantation.
The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
But back in the 1970s, scientists showed that children can sometimes regrow the tip of an amputated finger, as long as there's a bit of nail left over and the wound isn't stitched up.
Answer and Explanation: The heaviest organ is the skin. This makes sense as the skin is also the largest organ of the human body. With an average weight of about 4.5kg or nearly 10lbs, the skin is much heavier than the second heaviest organ, the liver.
Mayflies, of the order Ephemeroptera, may spend 2–3 years as nymphs at the bottom of lakes and streams and then live for as little as an hour as winged adults.
An unexpected discovery made by an international team, examining the results of an EEG on an elderly patient, who died suddenly of a heart attack while the test was in progress. What happens in our brain when we make the transition from life to death?
