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.
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 end of the penis, called the glans penis, has a high concentration of nerve endings, resulting in very sensitive skin that influences the likelihood of ejaculation (see ). The skin from the shaft extends down over the glans and forms a collar called the prepuce (or foreskin).
The outer part of your shoulders has thick skin with few nerve endings, making it one of the least painful places to get tattooed.
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.

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.
The trigeminal nerve is a mixed cranial nerve responsible for sensory data such as tactition (pressure), thermoception (temperature), and nociception (pain) originating from the face above the jawline; it is also responsible for the motor function of the muscles of mastication, the muscles involved in chewing but not ...
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.
Your fingertips are far more sensitive to touch. They have more nerve endings than your arm or back. Our fingers' high degree of sensitivity makes us able to tackle many delicate tasks, from rapid texting to surgery.

Those bundles contained a total of 4389 ± 1661(Mean ± SD) nerve fibers.

Also lost are branches of the dorsal nerve, and between 10,000 and 20,000 specialized erotogenic nerve endings of several types.
First, there are specific pain receptors. These are nerve endings, present in most body tissues, that only respond to damaging or potentially damaging stimuli. Second, the messages initiated by these noxious stimuli are transmitted by specific, identified nerves to the spinal cord.
Tooth nerves enable us to sense bite quality and distinguish between, say, a hard but biteable nut that we should eat and an unbiteable stone that we shouldn't. The nerve endings in teeth contain the stem cells that formed the enamel and dentine in the original tooth formation.
The soles of your feet contain more sweat glands and sensory nerve endings per square centimeter than any other part of the body.
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.
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.
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 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.
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.
