The tongue, lips, and fingertips are the most touch- sensitive parts of the body, the trunk the least.
Our forehead and fingertips are the most sensitive to pain, suggests research that used lasers to give volunteers sharp shocks across their body. The study was the first to look at how our ability to work out where something hurts – called “spatial acuity” – varies across the body.
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. This is illustrated as the distance where the two points can be felt as separate.
Your fingertips are far more sensitive to touch. They have more nerve endings than your arm or back.
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. This activity is based on a physical exam used in medical checkups.

The most sensitive areas were the thenar area, the skinfold between thumb and index finger and the area around os pisiforme. When the hand was repeatedly exposed to EASP, the PPT decreased with increasing number of pressure incidents.

The brain has no nociceptors – the nerves that detect damage or threat of damage to our body and signal this to the spinal cord and brain.
The smallest nerve in the human body is the trochlear nerve. It allows the superior oblique muscle of the eye to move. It is feasible to look down because of this. The nerve also allows for eye movement toward or away from the nose.
The forehead and fingertips are the most sensitive parts to pain, according to the first map created by scientists of how the ability to feel pain varies across the human body.
Skin: The skin is our body's most sensitive organ.
When it comes to pressure, the clitoris and nipple are the most sensitive, and the side boob and abdomen are the least. Lastly, when it comes to vibration, the clitoris and nipple are most sensitive. The clitoris was the most sensitive to vibration out of all the body parts.
The sciatic nerve is the thickest (approximately 2cm in wide) nerve in the body which travels in the posterior compartment of the thigh and supplies major part of the lower extremity. At the upper aspect of popliteal fossa, it branches medially to the Tibial Nerve and laterally to the Common Peroneal Nerve.
Sciatic Nerve and Sciatica. The sciatic nerve is the longest, largest nerve in your body. Your sciatic nerve roots start in your lower back and run down the back of each leg.
The sciatic nerve is the largest nerve in the human body.
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.
Brains can work 24 hours a day with no rest.
Vestigial organs and body parts refer to those that have little or no purpose in humans. They are a vestige left over from our ancestors. We have more than 100 vestigial anomalies, the most renowned of which are the appendix, wisdom teeth, coccyx, external ear, and male nipples.
They found that, regardless of gender, the smaller the fingertips, the finer the sense of touch. Littler fingertips are likely more sensitive because of the distribution of sensory receptors—the less surface area to spread out across, the closer together the receptors are.
Your clitoris has more nerve endings than any other part of your vulva. Together, these nerves can produce a range of pleasurable sensations, depending on how your clitoris is touched and how sexually aroused you are.
Pinch the skin on your elbow as hard as you can. It barely hurts because different areas of your skin have different nerve endings. Tough skin, like that on elbows, has fewer pain detectors. Parts of your body at a higher risk from being damaged have more nerve endings, so are more sensitive.
Your lips are 100 times more sensitive than your fingertips. Your lips have more than a million different nerve endings, making them one of the most sensitive parts of your body (and 100 times more sensitive than your fingertips). They're even more sensitive because there's no defensive membrane to protect them.
Women stated that their favorite part of the male physique was their chest at 24%. This was closely followed by hair 22% and arms at 19%. For the ab crowd, 13% prefer defined upper abs and 9% prefer the v-cut. Eyes, face, and legs came in at 3%, 2%, and 1%, respectively.
