Each spinal nerve innervates a band of skin called a dermatome. The shingles virus reactivates in a dorsal root ganglion and travels down the corresponding spinal nerve, ultimately causing inflammation in the associated dermatome.

HGH is released during NREM, Stage 3 sleep. Theta and delta waves appear as blood rushes from the brain to muscles for reparation.

The G alpha subunit activates adenylyl cyclase, which converts ATP into cAMP.
