        | Now, what happens if you lesion just the sensory components of a single spinal nerve, e.g., C6? |  | Definition 
 
        | Lesioning spinal nerve C6, its ventral ramus, or its dorsal root, will produce hypesthesia distributed in all cutaneous “patches” having the C6 dermatome. However, there will be severe hypesthesia or even anesthesia in the autonomous region of the C6 dermatome (skin over thenar eminence and thumb pad). |  |

        | What happens if a terminal nerve or its cutaneous branch is lesioned? |  | Definition 
 
        | Lesioning the terminal cutaneous nerve (e.g., the cutaneous brs. of the musculocutaneous nerve) produces severe hypesthesia and even anesthesia of the dermatomes represented in its patch because both the dermatomes and their overlaps are carried in that cutaneous nerve and thus, are “knocked out” |  |

 | Definition 
 
        | Abnormal episodic vasospasm of the digits in response to cold exposure. Upon warming, the affected digits undergo reactive hyperemia, becoming engorged with blood.
