The part of the body that has the most nerve endings is probably the fingertips. Each fingertip contains approximately 3,000 nerve endings called Meissner's corpuscles, which are designed to detect light touch and vibration.
When you want to get a good sense of how soft something is, such as a cat's fur, you touch it with your fingers, not your arm or the back of your hand. Your fingertips are far more sensitive to touch. They have more nerve endings than your arm or back.
Your fingertip
The ends of your fingers are more sensitive to pain than almost any other part of the body, according to an Annals of Neurology study. That's why tiny injuries like paper cuts and finger pricks can cause a grown man to wince.
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.
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.
Trigeminal neuralgia (TN), also known as tic douloureux, is sometimes described as the most excruciating pain known to humanity. The pain typically involves the lower face and jaw, although sometimes it affects the area around the nose and above the eye.
Free nerve endings are the most abundant type of nerve endings. They lie near blood vessels between epithelial layers of the skin, the cornea, the alimentary tract, and in connective tissues. In joints, they are found between the synovial and fibrous layers, and within the fibrous layer itself.
The radial nerve aids arm, wrist, hand and finger movements. It also sends touch, pain and temperature sensations to the brain.
Meissner's Corpuscles
Also lost are branches of the dorsal nerve, and between 10,000 and 20,000 specialized erotogenic nerve endings of several types.
Numbness, tingling, and hypersensitivity are common after a fingertip injury. In most patients, however, the nerve endings regenerate and the sensation improves gradually over time.
The left-hand little finger, aka pinky, is the smallest and weakest of our fingers. It is shorter than other fingers. And we rarely use it in isolation in everyday life.
Of all your fingers, you might think your pinky is the most useless. But your little finger is particularly important in a strong grip and hand surgeons agree if you're going to lose one, the index finger is the best one to lose.
So, even though the ring finger is the weakest finger on the hand, it is still an important finger for guitarists. If you have trouble with your ring finger getting caught on the strings, try practicing with a lighter gauge of string. You can also try using a fingerguard to help protect your finger.
Median nerve compression at the hand and wrist is called carpal tunnel syndrome. It is the most common type of nerve injury and results from compression of the median nerve at the wrist as it passes between the carpal bones and the flexor retinaculum.
The Heart, Pericardium, and Lung meridians are located on the palm side of the index and ring finger. The Liver, Spleen, and Stomach meridians are located on the palm side of the thumb and little finger.
sciatic nerve, largest and thickest nerve of the human body that is the principal continuation of all the roots of the sacral plexus.
Conclusion: The highest-quality studies suggest that medical male circumcision has no adverse effect on sexual function, sensitivity, sexual sensation, or satisfaction.
The present study shows in a large cohort of men, based on self-assessment, that the foreskin has erogenous sensitivity. It is shown that the foreskin is more sensitive than the uncircumcised glans mucosa, which means that after circumcision genital sensitivity is lost.
Morris' systematic review carried out in Australia [23] on early MC, with a total of 40,473 men, showed that medical circumcision (MC) does not adversely affect sexual function, sensitivity or pleasure.
Numbness in hands is a condition that many people experience. It can happen while a person sleeps, while talking on a phone or even driving a car. The numbness can be caused by increased pressure on a nerve in the palm of the hand. Many refer to this as Carpal Tunnel Syndrome.
The depth of the palmar digital nerves was about 3 millimetres, but less at the digital creases, and their diameter lay between 1 and 1.5 millimetres as far as the distal digital crease. Clinical applications of the findings are discussed.
The vein that supposedly went from the fourth finger to the heart was even dubbed the vena amoris by ancient Romans (Latin for the “vein of love”). Unfortunately, we now know that this ancient belief is not true -- there is no vein that runs from our ring fingers to our hearts.
When a nerve is cut, both the nerve and the insulation are broken. Injury to a nerve can stop the transmission of signals to and from the brain, preventing muscles from working and causing loss of feeling in the area supplied by that nerve.
The nerve fibers can be destroyed by severing them with a surgical instrument or burning them with a chemical or electrical current. In most cases, rhizotomy provides immediate pain relief that can last up to several years until the nerve recovers and is able to transmit pain again.
Free nerve endings are sensitive to painful stimuli, to hot and cold, and to light touch. They are slow to adjust to a stimulus and so are less sensitive to abrupt changes in stimulation.
