All of the following are types of sensory corpuscles in the skin EXCEPT:

The correct answer is identified as the Basal corpuscle because it is not recognized as a type of sensory corpuscle in the skin. The other options—Pacinian corpuscles, Meissner corpuscles, and Ruffini corpuscles—are well-established structures within the skin that are involved in the sensation of pressure, touch, and temperature.

Pacinian corpuscles, for instance, are responsible for detecting deep pressure and vibration; they are located deeper in the dermis and can sense rapid changes. Meissner corpuscles are more superficial and are sensitive to light touch and texture, crucial for fine tactile discrimination. Ruffini corpuscles are involved in sensing skin stretch and joint movement.

In contrast, the term "Basal corpuscle" does not correspond to any recognized structure in the context of sensory perception within the skin, making it the clear exception among the listed options. Understanding the specific roles and locations of these sensory corpuscles aids in grasping how the skin processes sensory information.
