Touch Sensitivity

Definition

Touch sensitivity refers to the ability of different parts of our body to detect and respond to tactile stimuli, such as pressure, temperature, and pain. It varies across body regions due to differences in the density and distribution of sensory receptors.

Dermatomes: Dermatomes are specific regions on our skin that are innervated by individual spinal nerves. Each dermatome has its own unique touch sensitivity level.

Sensory Adaptation:

Sensory adaptation is when our sensory receptors become less responsive over time when exposed to continuous stimulation. This phenomenon can affect touch sensitivity.

Two-Point Threshold: The two-point threshold is the minimum distance required between two points of stimulation for us to perceive them as separate touches rather than one. It helps determine touch sensitivity in different body regions.
