Solution
It seems like you're asking for an explanation of how the Pacinian corpuscle, a type of nerve ending, responds to different types of stimuli. Here's a step-by-step explanation:
A. When a light touch is applied to the Pacinian corpuscle, a receptor potential (a type of electrical change) is generated. As the pressure of the touch increases, the size of the receptor potential also increases. When this potential reaches 30 mV, an action potential (a rapid rise and subsequent fall in voltage or membrane potential) is produced at a point of the sensory nerve within the corpuscle.
B. When a light touch is applied to the Pacinian corpuscle, a receptor potential is generated. As more receptors are brought into the receptive field (the specific part of the world to which a receptor organ and receptor cells respond), the size of the receptor potential increases. When this potential reaches 30 mV, an action potential is produced at the first node of Ranvier (a gap in the myelin sheath of a nerve).
C. When sustained pressure is applied to the Pacinian corpuscle, a receptor potential is generated. As more receptors are activated, the size of the receptor potential increases. When this potential reaches 10 mV, an action potential is produced at the first node of Ranvier.
D. When rapid vibration is applied to the Pacinian corpuscle, a graded receptor potential (a change in resting potential that varies depending on the strength of the stimulus) is generated. When the receptor potential reaches 10 mV, an action potential is produced at the first node of Ranvier.
E. When rapid vibration is applied to the Pacinian corpuscle, a receptor potential is generated. When the receptor potential reaches 10 mV, an action potential is produced in the unmyelinated portion of the sensory fiber (the part of the nerve without a myelin sheath).

Receptor Physiology Cutaneous mechanoreceptors respond to mechanical stimuli that result from physical interaction, including pressure, tension, and vibration. Cutaneous mechanoreceptors with small, accurate receptive fields are found in areas needing accurate taction (e.g. the fingertips). In the fingertips and lips, innervation density of mechanoreceptors are greatly increased. Mechanoreceptors found in areas of the body with less tactile acuity tend to have larger receptive fields. With Two-Point Discrimination, you will now observe that the density of touch receptors varies greatly in different parts of the body. Using calipers and a metric ruler, test the subject’s ability to differentiate two distinct points touching the skin at the same time. Have the subject close their eyes. Starting with the face and with the calipers closed, touch the subject’s skin and ask them to indicate if they felt one or two points of contact. Move the calipers apart and again touch the subject with both ends of the calipers at the same time and ask if it was one or two. Continue to do so until the subject indicates that they felt two points of contact and note the distance of the calipers. 13. Two-Point Discrimination Face: Forearm: Neck: Finger:
