Divisions of the Nervous System: Use the following word bank to complete the paragraphs. NAME:________________________________ Central Nervous System Glands Sensory Sensory Input Sympathetic Division Autonomic Nervous Parasympathetic Somatic Nervous System System (x3) Peripheral Nervous (x2) Muscles Motor Interneurons Increases Skeletal Motor Neurons System (x2) Energy 1. The nervous system can be divided into two main sections. The ________________________________ includes the brain and spinal cord. It also completes integration with the help of ______________________________. The second part of the nervous system is called the _______________________________________________. It allows us to complete ________________________________ with sensory neurons and uses ____________________________ to accomplish a motor output. 2. The ________________________________can be broken down further in to multiple divisions. The first separation occurs when we delineate between our senses and our movements. The ______________________division accumulates information from the external environment as well as the internal environment. The ______________________ division carries messages to _________________________ and ___________________. 3. The motor division is then broken into two more separate systems: ______________________________________ and the ____________________________________. The __________________________________is responsible for mostly voluntary actions involving the ________________________system. The ________________________________ carries signals to mostly our organs and is mostly involuntary. 4. To continue, the __________________________________ is then divided into two more divisions. These divisions can increase energy level or decrease energy level. The ________________________________ division prepares our body for intense activity which _____________________ overall energy level. The ____________________________ division will calm the body down and return it to normal maintenance functioning. This lowers the overall ___________________________ level. Using your knowledge of the nervous system answer the following questions : 1. Match the terms in Column B with the appropriate function descriptions in Column A. Column A Column B _____ Takes information from external/internal environment A. Peripheral _____ Made up of motor neurons and further broken into 2 divisions B. Motor Division _____ All parts of the nervous system but the brain and spinal cord C. Sensory Division _____ Increases energy within your body D. Autonomic _____ Returns your body to normal maintenance function E. Somatic _____ Controls involuntary movement F. Sympathetic _____ Regulates voluntary movement G. Parasympathetic 2. __________ When Mr. Valdez thought his 1-year-old daughter had fallen down the stairs, his heartbeat accelerated, his blood pressure rose, and he began to perspire heavily. Mr. Valdez’s state of arousal was activated by his ________ nervous system. a. parasympathetic c. somatic b. sympathetic d. central c. somatic 3. __________ The parasympathetic nervous system is a division of the ________ nervous system. a. autonomic b. somatic c. central d. sympathetic 4. __________ The part of the peripheral nervous system that controls the movement of your legs when you walk is the: a. reticular formation. b. sympathetic nervous system. c. somatic nervous system. d. parasympathetic nervous system. 5. __________ Which of the following is a function of the motor division of the nervous system? a. providing sensation of the internal and external environments b. integrating sensory information c. coordinating voluntary and involuntary activities d. sending signals to muscles e. regulating or controlling peripheral structures and systems 6. Briefly explain why each statement is incorrect or misleading. a. The parasympathetic division of the autonomic nervous system slows digestion. b. Nerve signals travel quickly through a neuron’s myelin sheath.
