The somatic nervous system includes the sensory and motor nerves that innervate the limbs and body wall. Sensory nerve fibers in the peripheral nerves are the peripheral axonal process of neurons in the dorsal root ganglion.he somatic nervous system includes the sensory and motor nerves that innervate the limbs and body wall.

Lightning damages the human body. It kills people directly close to trees or the ground. The kind of lightning that usually hits people is cloud to ground lightning. Lightning can affect all organs in the body. A lightning strike can give you cardiac arrest which is when your heart stops beating. Lightning can change the hearts rhythm but the heart usually resumes its normal heart rhythm. CPR can often revive these people.
Lightning strikes, lasting less than a half-millionth of a second, often scorch the skin but don't cause internal burns. Just as crucial, most of the electricity in a lightning bolt does not pass through the body. Rather, it dissipates over the skin in what's known as a flashover. Vernon Cooray, a lightning scientist at Uppsala University in Sweden, explains the phenomenon by contrasting the ways a human body and a tree react when struck.
