Nervous SystemHow did our nervous system work in the Impulse Activity we just completed?We sensed the touch.A message was sent to our brain.Our brain sent a message to our muscles.Our muscles squeezed the hand.
-
Organs of the Nervous SystemBrain= uses information it receives from nerve impulses to coordinate actions
-
Organs of the Nervous SystemNerves= carry messagesthroughout thebody
-
Organs of the Nervous SystemSpinal Cord= Central communication system. Nerve centerMessages are sent to the brain through the spinal cord.Exception: Reflexes skip the spinal cord and go straight to the brain.
-
Functions of the Nervous SystemFunctions include:Control centerCommunication networkCoordinates all actions and reactionsSend messages as electrical impulses
-
Functions of the Nervous SystemFunctions include:Allows us to ThinkEvaluateRemember
-
Functions of the Nervous SystemFunctions include:Sensory Input- Senses send messages to the brain.Integration- The brain interprets and translates.Motor Output- The brain sends messages to body.
-
Functions of the Nervous SystemFunctions include: Central Nervous System- Maintains homeostasis by regulating vital body functions such as breathing, heart rate, hormones, etc.
-
Functions of the Nervous SystemFunctions include: Peripheral Nervous System- Sensory Neurons- Carry information toward the central nervous systemMotor Neurons- Send impulses away from the central nervous system
