ANATOMY

Detailed explanation-1: -For example, when you feel a mosquito land on your arm, your sensory neurons send signals to interneurons in your brain. Then, your brain sends signals to your motor neurons to swat the mosquito.

Detailed explanation-2: -When you feel a bug on your arm, your somatic nervous system is critical to the sensation. The sympathetic nervous system enables the body to conserve and store its energy. The parasympathetic nervous system mobilizes the body for action.

Detailed explanation-3: -Somatosensory pathways relay information between the brain and nerve cells in the skin and organs. For example, these pathways are how Patrick knows that someone is tickling his left foot. But, why doesn’t he feel tickling on his right foot?

Detailed explanation-4: -Your sense of touch below your neck uses your somatic nervous system to reach your spinal cord, which then relays signals to your brain.
