The ________ are distributed throughout the dermal papillae and are involved in ________ touch.
A) Merkel disks; very deep
B) Pacinian corpuscles; very light
C) Muscle spindles; fine proprioceptive
D) Golgi tendon organs; limited awareness
E) Meissner corpuscles; two-point discrimination
Meissner Corpuscles
Specialized nerve endings in the skin responsible for sensitivity to light touch.
Two-Point Discrimination
The ability to discern two separate points of contact on the skin, a measure of tactile sensory resolution.
Dermal Papillae
Small, nipple-like extensions of the dermis into the epidermis that increase surface area for oxygen and nutrient transfer between these layers.
- Recognize the sensory receptors linked to various sensations such as pain, temperature, and touch.

Final Answer :
E
Explanation :
Meissner corpuscles are specialized nerve endings located in the dermal papillae, particularly in areas of the skin that are sensitive to touch, such as the fingertips and lips. They play a crucial role in the sensation of two-point discrimination, which allows us to distinguish between two points touching the skin closely together. This ability is essential for tasks that require fine tactile discrimination.
