SHOCK TO THE SYSTEMS [ THE NERVOUS SYSTEM ( HARMONY ) ]

ByTeam HUMANITYUAPD

SHOCK TO THE SYSTEMS [ THE NERVOUS SYSTEM ( HARMONY ) ] When you’re startled, the two branches work together, regulating the body without any conscious thought needing to be involved. Thanks to these automatic responses, the brain’s cortex is allowed to remain free to do other things-process sensory information, register emotion, pursue rational thoughts,…
