The brain itself has the least feeling because it lacks pain receptors (nociceptors), meaning it can't feel pain directly, even though it processes pain signals from the rest of the body; other body parts with very little sensation include hair, nails, and certain internal organs like the intestines (when stretched) and the peritoneum.
Although its not normally touchable, your brain is the least sensitive part of your body. Touching the surface of the brain would be completely painless as there are no pain receptors.
The correct answer is Brain. Brain organs will not feel any pain on being pricked by a needle. The brain is a painless organ. So pricking or even removing a part of the brain, while a person is conscious, does not cause any pain.
The least sensitive skin on the human body is generally found on the palms of the hands and the soles of the feet. The skin in these areas has fewer nerve endings compared to other parts of the body.
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.

Congenital insensitivity to pain is a rare disorder, first described in 1932 by Dearborn as Congenital pure analgesia. Congenital insensitivity to pain and anhydrosis (CIPA) is a very rare and extremely dangerous condition. People with CIPA cannot feel pain [1].
Two of the important body parts are nails and hair. These are made of special tissues. We don't feel anything when we cut our nails and hair.
The periosteal layer (an outer membrane) of bone tissue is highly pain-sensitive and an important source of pain in several disease conditions causing bone pain, like fractures, osteoarthritis, etc.
Burn injury survivors usually suffer a great deal of pain during their entire course of treatment and thereafter up to 7-12 years.
The brain itself does not feel pain because there are no nociceptors located in brain tissue itself. This feature explains why neurosurgeons can operate on brain tissue without causing a patient discomfort, and, in some cases, can even perform surgery while the patient is awake.
You have pain receptors (nociceptors) throughout your body, including your visceral organs, that detect changes in your body. They notice signs that something's wrong, including: Increased pressure.
Congenital insensitivity to pain with anhidrosis.
It's characterized by the inability to feel physical pain and the inability to sweat from birth. People with CIPA often have recurrent fevers, an inability to perceive temperature extremes, developmental delays, behavioral problems, and hypotonia.
Nociceptors are present in many body tissues but have not been found in articular cartilage, visceral pleura, lung parenchyma, pericardium, brain, and cord tissue.
Introduction. The main dimensions of the sensorial component of pain are pain tolerance and pain intensity (Crombez et al., 1999; Masedo and Esteve, 2007; Meesters et al., 2019). Pain tolerance is defined as the maximum amount of pain that a person can bear (Philips, 1988).
The neuroimmunocutaneous system (NICS) is responsible for the cutaneous sensations of touch, pressure, temperature, and pain. This sensory transduction occurs via primary afferent nerves following reciprocated signals between neuronal and nonneuronal skin cells of the NICS [1].
“It's not a myth: Rainy, damp weather really can magnify joint stiffness and pain,” says Mark Shekhman, MD, an orthopedic surgeon at the Bone & Joint Institute at Hartford Hospital. That's especially true if your joints are already inflamed or have less cushioning — due to arthritis, an old injury or any other reason.
What Are The 10 Most Painful Bone Fractures
So the brain itself doesn't feel pain. This has been demonstrated in neurosurgical procedures, in which stimulation of the brain tissue itself in patients who are awake did not cause pain.

Men's fingernails grow faster than women's nails. But, women's fingernails do grow faster during pregnancy due to hormones. Our fingernails have no feeling.
The insular cortex (IC) has a role in both sensory and affective perception of pain – the suffering aspect of pain. It is often coactivated with the anterior cingulated cortex. In chronic pain, there is a more widespread activation of the IC compared to acute pain.
African–Americans report greater sensitivity (i.e., lower pain threshold) and reduced pain tolerance to a variety of quantitative sensory testing methods when compared with non-Hispanic whites, including thermal pain [21–24], cold pressor pain [25], ischemic pain [6], electrical stimulation [26] and, perhaps most ...
When a part of your body is injured, special pain receptors from that area release chemicals called neurotransmitters, which send messages to your brain. The messages travel along nerves to the spinal cord and eventually to the brain, telling it, “Something might be wrong here, pay attention!”
Some people are born without the ability to feel physical pain, a condition called congenital analgesia. People who can't feel pain also cannot smell, a condition called anosmia. In anosmia, there is nothing pathologically wrong with the nose.
