The tongue, lips, and fingertips are the most touch- sensitive parts of the body, the trunk the least. Each fingertip has more than 3,000 touch receptors, many of which respond primarily to pressure.
Those results showed that the areas of the body that are most sensitive to pain are the fingertips and the forehead. Most of us have probably experienced pain in the fingertips, such as touching something very hot.
We must remember that the most delicate organ in the human body is the brain. Brain is one of the largest and most complex organs of the human body and is made up of more than 100 billion nerves. Brain controls speech, thought, memory, movement and helps in the functioning of many organs in the human body.
Muscle, tendons, ligaments, fat, fibrous tissue, lymph and blood vessels, fasciae, and synovial membranes are all examples of soft tissue that connects, surrounds or supports internal organs and bones. Fats are widely regarded as the softest tissues.
Areas including the fingertips, lips, and tongue have very high resolution, and therefore are the most sensitive. Other areas like the forearms, calves, and back are the least sensitive.
Some places, such as our fingers and lips, have more touch receptors than other parts of our body, such as our backs. That is one reason why we are more sensitive to touch on our fingers and face than on our backs.
Detailed Solution. The correct answer is Brain. Brain organs will not feel any pain on being pricked by a needle. The brain is a painless organ.
The foot, lower leg and upper chest are much less sensitive than average; in comparison, the cheek, neck back, and seat area are 2–3 times as sensitive to both cooling and warming stimuli. Every body part exhibits stronger sensitivity to cooling (1.3–1.6 times stronger) than to warming.
When skin hurts to touch, it means your nerves are oversensitive or your brain is overreacting to stimulus. A number of pain conditions can make you hypersensitive to pain, like migraines, diabetes, shingles, and complex regional pain syndrome. There are medications and treatments that can help you cope with the pain.
That's because your skin's touch receptors aren't evenly distributed—some areas have more and others have a lot less. In this activity, you'll learn more about your sense of touch by testing your body's own reactions.
Your Sensitive Side
For example, recent research shows that one side of your body may experience pain differently than the other side. A study published in the December 2009 issue of Neuroscience Letters showed that right-handed study participants could tolerate more pain in their right hands than in their left hands.
So no we can say that the only organ which hasn't nerve supply is the Computer itself (the Brain). But it doesn't mean that if a nerve supply of an organ is cut, that organ will not work, it works but with no control.
CIPA is a rare genetic disorder that makes you unable to feel pain or sweat. It's caused by a defective gene that disrupts the normal development of sensory and autonomic nerves. The lack of pain means you might not know when you get hurt.
The brain itself doesn't feel pain. Though the brain has billions of neurons (cells that transmit sensory and other information), it has no pain receptors. The ache from a headache comes from other nerves — inside blood vessels in your head, for example — telling your brain something is wrong.
Our sense of touch is so sensitive that we can feel the difference of just a single layer of molecules, researchers have found. We can easily tell the difference between a range of surfaces, from the roughest of sand paper to a soothing caress.
The tongue, lips, and fingertips are the most touch- sensitive parts of the body, the trunk the least.
Studies have found that the female body has a more intense natural response to painful stimuli, indicating a difference between genders in the way pain systems function. A greater nerve density present in women may cause them to feel pain more intensely than men.
However, even though fingertips have the highest concentration of nerve endings per square inch, other areas like lips, tongue and genitals also contain unique types of nerves responsible for providing different sensory experiences- like taste in our mouths or sexual pleasure from our genitalia.
Your fingertips are densely packed with nerve endings, which send pain signals straight to your brain. And more nerve endings equal more pain signals.
Highly sensitive areas such as the fingertips and tongue can have as many as 100 pressure receptors in one cubic centimeter. Less sensitive areas, such as your back, can have as few as 10 pressure receptors in one cubic centimeter.
Answer: The eyeball is the only organism which does not grow from birth. It is fully grown when you are born. When you look at a baby's face, so see mostly iris and little white.
The appendix may be the most commonly known useless organ.
Many years ago, the appendix may have helped people digest plants that were rich in cellulose, Gizmodo reported. While plant-eating vertebrates still rely on their appendix to help process plants, the organ is not part of the human digestive system.
Your vital organs include your liver, kidneys, heart, brain, lungs and small intestine.
Some people can handle more pain than others
Everyone's pain tolerance is different and can depend on a range of factors including your age, gender, genetics, culture and social environment. The way we process pain cognitively affects our pain tolerance.
