Deforming the corpuscle creates a generator potential in the sensory neuron arising within it. This is a graded response: the greater the deformation, the greater the generator potential. If the generator potential reaches threshold, a volley of action potentials (nerve impulses) are triggered at the first node of Ranvier of the sensory neuron.
Merkel nerve endings provide information on pressure, position, and deep static touch features such as shapes and edges. They are tactile sensors in the business of mechanotransduction . They encode surface features of touched objects into perception, but also have to do with proprioception .
The C fiber axons conduct more slowly at speeds from 0.4 to 2 meters/second due to their smaller diameters and little or no myelination of their axon. [ 8 ] [ 4 ] As a result, pain comes in two phases: an initial extremely sharp pain associated with the Aδ fibers and a second, more prolonged and slightly less intense feeling of pain from the C ...
supraorbital pressure - this is the manual stimulation of the supraorbital nerve by pressing a thumb into the indentation above the eye, near the nose. [ 2 ] sternal rub - this involves creating a turning pressure (akin to a grinding motion with a pestle and mortar) on the patient's sternum [ 1 ]

This is because a muscle spasm refers to the entire muscle contracting whereas the local twitch response also refers to the entire muscle but only involves a small twitch, no contraction.
