Correct Answers

Functions of the Nervous System? - CORRECT ANSWER✔✔-1) Sensory-
| | | | | | | | |



detecting internal and external stimuli
| | | | |




2) Integrative- Processing of sensory information
| | | | | |




3) Motor- eliciting a response by activating effectors, such as muscles
| | | | | | | | | | |



and glands
|




How is the Nervous System organized? - CORRECT ANSWER✔✔--
| | | | | | | |



Neurons
-Neuroglial


Central Nervous System (CNS) - CORRECT ANSWER✔✔-Responsible for
| | | | | | | |



integration of incoming sensory information, generation of motor
| | | | | | | |



commands, and thoughts and memories | | | |




Peripheral Nervous System (PNS) - CORRECT ANSWER✔✔-Made up of
| | | | | | | | |



nervous tissue outside of the CNS
| | | | |




-Cranial Nerve: arise from the brain
| | | | | |




-Spinal Nerve: arise fro spinal cord
| | | | | |

, -Ganglia: clusters of nervous tissue
| | | | |




-Enteric Plexuses: networks in GI tract organ walls
| | | | | | |

| | | | | | | |



and special sensory receptors to CNS
| | | | | |




-Motor neurons: to skeletal muscles under voluntary control from CNS
| | | | | | | | |




Autonomic (ANS) - CORRECT ANSWER✔✔--Sensory neurons: from
| | | | | | |



visceral organs to CNS
| | |




-Motor neurons: to smooth muscle, cardiac muscle and glands under
| | | | | | | | | |



involuntary control from CNS | | |




Enteric (ENS) - CORRECT ANSWER✔✔--Function somewhat
| | | | | |



independently of ANS and CNS | | | | |




-Monitors GI tract and controls operation involuntarily
| | | | | |




Neuroglia - CORRECT ANSWER✔✔--Divide by mitosis
