ANATOMY 2 LAB 1 – RECEPTORS
Questions:
1. How is the distance between receptors related to sensitivity of a stimulus? * The greater the distance between receptors and stimulus the lesser sensitive are the stimulus. The smaller area, the more sensitive. 2. What does the two-point discrimination test measure? * It measures the smallest distance at which two points of contact can be felt or measures areas that are more sensitive and has more motor interactions. 3. What areas of the body have a greater density of receptors? * Lips, palm of hands, ventral forearm 4. What happens when receptors adapt? * When a stimulus is applied for a prolonged period, the rate of receptor response slows down and our conscious awareness of the …show more content…
TESTING TACTILE LOCALIZATION Body Area Tested | Average Error (mm) | Palm Of Hand | 20 | Fingertip | 2 | Ventral Forearm | 28 | Back of Hand | 18 | Back of Neck | 19 |
Questions & Answers: * Does the ability to localize the stimulus improve the second time? * NO. * The third time? * NO. * Explain: * Density of Meissner’s corpuscles (touch receptors) does not change.
* Which area has the smallest error of localization? * Fingertips
LAB ACTIVITY 4. PLOTTING THE RELATIVE DENSITY AND LOCATION OF TOUCH AND TEMPERATURE RECEPTORS.

* How does the density of the heat receptors correspond to that of the touch receptors? * Heat receptors perceive hot sensations when receptors take over. * To that of the cold receptors? * It damaged the skin’s underlying tissue. * On the basis of your observations which of these three types of receptors appears to be most abundant (at least in the area tested?)
