Question

Which functionality would be most affected if you lost your SA II (Ruffini) touch receptors?

Answer 1

Answer:

C. Sensitivity to finger position and downward skin pressure, as when holding an object

Explanation:

SA II fibers a form of the Ruffini respond particularly to lateral skin stretch and direction of object motion, they terminate in Ruffini endings connected to Aβ nerve endings.

Sensitivity to finger position and downward skin pressure, as when holding an object would be most affected if you lost your SA II (Ruffini) touch receptors.

Answer 2

Answer:

option C

Explanation:

Ruffini corpuscles functions primarily in sensing skin stretching, movement, and finger position.  These Ruffini touch receptors also detect tension deep in the skin. the Merkel nerve ending function in Texture perception and pattern/form perception, like for reading Braille. The ability to detect stable grasp and whether an object is slipping is detected by the Meissner's corpuscles.
