Two-point threshold is smallest in the finger (2 mm). Two-point threshold on the forearms is 30 mm; on the back it is 70 mm.
Which body area has the finest 2 point discrimination threshold?
There is a great difference in the spatial discrimination ability among body regions, with the best results achieved at the tip of the tongue (1–2 mm), followed by lips and fingertips (2–4 mm), whereas at the back of the hand a distance of 20–30 mm is necessary to distinguish one from two stimuli.
What body parts have the smallest two-point discrimination?
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.
What does a small two-point threshold mean?
Definition of two-point threshold : the smallest separation at which two points applied simultaneously to the skin can be distinguished from one.
What parts of the body have the largest spatial threshold?
The glabrous skin of the hand and the forehead were the areas of highest spatial acuity, regardless of the method used (pairs of successive or simultaneous stimuli), for both touch and pain.
What parts of the body are most and least sensitive to two-point discrimination?
Different areas of the body have receptive fields of different sizes, giving some better resolution in two-point discrimination. 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.
Which areas of the skin are most sensitive to the two-point discrimination test?
They advised that the skin must be touched simultaneously and with equal pressure to accurately test two-point discrimination. These authors concurred that the tip of the tongue (1.5 mm) and finger tips (2–3 mm) were far more sensitive than the cheeks and the back of the hands (12 mm).
What body part has the largest two-point discrimination?
Parts of the body with the highest densities of touch receptors will have the greatest degree of two-point discrimination. Places such as the fingertips and lips will be able to sense 2 toothpicks even when they’re very close together.
Which region of the upper appendage has the worst two-point discrimination?
upper arm and front of thigh are the body parts with the largest variation in 2point discriminations.
What does a small 2 point threshold mean?
Definition of two-point threshold : the smallest separation at which two points applied simultaneously to the skin can be distinguished from one.
What is the two-point threshold and what does it indicate?
The two-point threshold refers to how far apart two points on the skin must be for an individual to recognize that they are being touched by two things at once. Learn more by exploring the definition, use, perception, distinguishing tactile sensations, and examples of the two-point threshold.
What has the smallest two-point threshold?
Two-point threshold is smallest in the finger (2 mm). Two-point threshold on the forearms is 30 mm; on the back it is 70 mm.

A Two-Point Discrimination Two-point discrimination is the ability to distinguish two compass points simultaneously applied to the skin. The normal minimal distance is 3 cm for the hand or foot and 0.6 cm for the fingertips.
What body part has the smallest spatial threshold?
Two-point threshold is smallest in the finger (2 mm). Two-point threshold on the forearms is 30 mm; on the back it is 70 mm. Fingers are analogous to the fovea in the retina (but different because they work best when scanned over an object).
Which body part has the highest two-point threshold?
Parts of the body with the highest densities of touch receptors will have the greatest degree of two-point discrimination. Places such as the fingertips and lips will be able to sense 2 toothpicks even when they’re very close together.
What is the most touch sensitive part of the body?
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.
What is the most innervated part of the body?
The hands and the face are the most highly innervated skin regions, as might be expected from the exaggerated cortical representation of these body parts (Penfield and Boldrey 1937).

Two-point discrimination (2PD) is the ability to discern that two nearby objects touching the skin are truly two distinct points, not one. It is often tested with two sharp points during a neurological examination: 632 : 71 and is assumed to reflect how finely innervated an area of skin is. In clinical settings, two-point discrimination is a widely used technique for assessing tactile perception.
