Skin: The skin is our body's most sensitive organ. The skin is the largest organ of the body, made up of water, nutrients, lipids, and mineral deposits.
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 tissue there, known as the retina, contains millions of light-sensitive cells. They are especially concentrated in an area called the fovea (FOH-vee-ah).
Clitoris. It's common knowledge that the clitoris is one of the most sensitive spots on a woman's body. It has 8,000 nerve endings that ultimately make it the powerhouse of pleasure.
The lips. Inner thighs and lower abdomen/pubic area. The nape of the neck. The nipples.
The nerve and muscle cells are the slowest to regenerate and are the least sensitive cells.
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.
Generally speaking, patients with lighter color irises, such as blue or gray, experience more light sensitivity than someone with brown eyes. The density of pigment in light eyes is less than that of a darker colored iris. When light hits a dark-colored iris, the higher density in pigment blocks the light rays.
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.
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.
The direction of sex differences in pain responses across multiple stimulus modalities and pain measures is highly consistent, with women showing greater sensitivity than men.
Brown eyes may have ranked as the least attractive, but they were 1.6 times more likely than blue eyes to be described as trustworthy.
Unbelievable as it may seem, the answer is yes—natural purple eyes do exist. Purple eyes are also commonly referred to as “violet eyes,” as they are typically a light shade. For most people, this striking eye color can only be achieved with the help of colored contacts.

Hormones may play a role in women having more pain sensitivity. In addition, women have greater nerve density (more nerves in a given area of the body)—which may cause women to feel pain more severely than men.
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.
The Stapedius, the smallest skeletal muscle in the human body, which is about 1 mm in length, is regarded to be the weakest muscle. It originates from a prominence known as the pyramidal eminence at the posterior edge of the tympanic cavity. It inserts into the stapes' neck.
Tooth enamel is the first line of defense your teeth have against plaque and cavities. It is the white, visible part of the tooth and it is also the hardest part of the human body.
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.
The pineal gland is the smallest organ in the human body. The pineal gland is located near the center of the brain. The name pineal comes as pineal is a small pine-shaped gland. The pineal gland controls the body's internal clock since it regulates the daily rhythms of the body.
The first heaviest organ is the skin with a mass of four to five kg. The liver is the second heaviest organ in the body, which discharges bile. The weight of the liver is about 1.5 kg. The brain is the third heaviest organ with an approximate mass of 1.5 kg.
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.
The rarest skin color in the world is believed to be the white from albinism, a genetic mutation that causes a lack of melanin production in the human body. Albinism affects 1 in every 3,000 to 20,000 people. People with albinism usually have very pale or colorless skin, hair, and eyes.
