Two-Point Discrimination

                                                                 Abstract                                 

Motivation

Sematosensation, also known as the sense of touch involves different sets of sensory and incorporates all sensation collected from the skin. The skin contains several types of receptors that differ from size and shape and are responsible for responding to a stimulus (Godde et al.,2016). The problem is essential because it provides information about what happens when the skin comes to contact with the surrounding environment.

Methods

The method used to obtain the results involved a lad experiment where the Subject is subjected to various sets of conditions on different body regions. The species used as human beings, students of age between 14-18 years. No sex difference was assessed during the experiment. Each area was randomly alternate between 1 point and 2 points of contact with a total of 5 trials for each body part, asking the Subject if they feel 1 or 2 points during each trial. If they respond to 4/5 trials correctly, then the test distance is continuously reduced until they are unable to respond correctly. When the Subject cannot differentiate between one or two points for at least 2/5 trials at a given distance, then the test is re-done in a more considerable range. If the Subject still responds correctly for at least 4/5 trials at the more considerable gap, the distance is recorded as the “Two Point Discrimination Threshold (Jung et al.,2019).”

 

 

Results

From the results obtained, I learned that body parts with glabrous skin are more active compared to hairy skin when exposed to the same environmental condition. Glabrous skin showed a proactive response to the stimulus when exposed to more considerable distances. Body parts with hairy skin reacted actively when the stimulus was closer and rubbing against it.

Conclusion

In conclusion, different body part responds differently when they are subjected to the same environmental conditions. It depends on the type of skin available at the body part, such as Glabrous and hairy skin.
