Organize the Nervous System
Sort the functions or characteristics into the appropriate parts of the nervous system. Central Nervous System Includes the brain Includes the spinal cord Command and integration center Peripheral Nervous System Includes cranial and spinal nerves transmits messages to and from the CNS Divided into the Somatic and Autonomic nervous systems Sensory Division Carries messages to the CNS from sensory receptors Afferent part of the PNS Motor Division Carries messages away from CNS to any effector Efferent part of the PNS Somatic Nervous System Voluntary Nervous System sends signals from the CNS to skeletal muscle Autonomic Nervous System Involuntary Nervous System Sends signals from the CNS to smooth muscle, cardiac muscle, and glands Can be divided into the sympathetic or parasympathetic divisions Sympathetic Nervous System Fight or flight In charge in emergency situations causes an increase in blood pressure and heart rate Parasympathetic Nervous System Resting and Digesting In charge in non-emergency situations Complete the chart showing the breakdown of the nervous system using terms from the word bank. Motor neurons Autonomic NS Afferent division Visceral stimuli Skeletal muscles Parasympathetic NS Sensory stimuli Efferent division Sympathetic NS Somatic NS Brain and spinal cord Smooth and cardiac muscle, glands Brain and spinal cord Afferent division Efferent division Visceral stimuli Sensory stimuli Autonomic NS Parasympathetic NS Sympathetic NS Motor neurons Skeletal muscles Smooth and cardiac muscle, glands Somatic NS Match each part of the nervous system with its main functions. central nervous system command center of NS peripheral nervous system nerves outside of the CNS sensory division afferent: messages go from sensory receptors to the CNS motor division efferent: carries impulses from the CNS to the effector organs somatic nervous system voluntarily control the skeletal muscles autonomic nervous system regulates automatic events, like activity of smooth and cardiac muscles sympathetic NS fight-or-flight response parasympathetic NS rest and digest response
