Figure 35.26 Which of the following statements is false? The parasympathetic pathway is responsible for relaxing the body, while the sympathetic pathway is responsible for preparing for an emergency. Most preganglionic neurons in the sympathetic pathway originate in the spinal cord. Slowing of the heartbeat is a parasympathetic response. Parasympathetic neurons are responsible for releasing norepinephrine on the target organ, while sympathetic neurons are responsible for releasing acetylcholine.
List the general sequence of events that occur in the nervous system from the time you see the ruler drop to the time you catch the ruler. List each of the nervous system structures involved, including each brain area used in this process. Start with the photoreceptors and end with the muscles in your forearm and fingers.
Describe the passage of information through the nervous system using a specific example. Be sure to include in detail: The collection of stimuli at the sense organ and receptors involved as well as graded potential. The passing of the impulse along ascending pathways. Location in the brain that processes the information. Sending out motor information from brain. The passing of the impulse down descending pathways. Response by a skeletal muscle.
This is a biology question regarding nerve impulses. Neurofibromatosis type 1 is a condition where tumours can grow in the nerves near the skin. The growth of tumours prevents the action potentials from quickly travelling through the neurons. Identify the nerve structure from the image below and the division of the nervous system affected by neurofibromatosis type 1. CNS = Central Nervous System PNS = Peripheral Nervous System Select one: a. Nerve Structure Division of Nervous System 3 PNS b. Nerve Structure Division of Nervous System 4 CNS c. Nerve Structure Division of Nervous System 5 PNS d. Nerve Structure Division of Nervous System 1 CNS
What is the primary purpose of the peripheral nervous system? To process information received from the environment and coordinate responses To transmit information toward or away from the central nervous system

Alcohol addiction is a condition in which a person experiencesdependent on alcohol and difficult to control its consumption. On the other hand, excessive alcohol consumption in the long term can cause disturbances in brain performance, including disturbances in memory, attention, coordination, and locomotion. How does alcohol affect the functioning of nerve cells and the central nervous system? What is the mechanism that occurs? Based on information from the literature, analyze what will happen to coordination and locomotion in someone who is addicted to alcohol and consumes large amounts of alcohol over a long period of time.
Which of the following defines the interneurons? Neurons that are excited by a specific environmental stimulus such as light or touch Neurons that serve as relay stations, receiving and transmitting signals between other neurons Neurons that control muscles and glands
Which of the following statements about neurons is FALSE? Efferent neurons carry signals away from the central nervous system.Axons carry signals away from the cell body.Interneurons are located in the CNS..The neurons of the autonomic nervous system are under voluntary control.The neurons of the sympathetic nervous system are activated during times of stress.
How would your nervous system respond if you encounter a snake on a hiking trail? Group of answer choices The parasympathetic nervous system would send signals to increase the heart rate, decrease salivation, and increase respiration. The somatic nervous system sends signals to the central nervous system to increase heart rate and respiration. The sympathetic nervous system would send signals to increase the heart rate, decrease salivation, and increase respiration. The autonomic nervous system would send signals to the somatic nervous system to increase respiration and heart rate.
Select all of the statements from the list below that are true. Within a single axon, an action potential is always of the same magnitude. (In other words, it always looks the same on a trace of the membrane potential.) All excitatory post-synaptic potentials trigger an action potential. Graded potentials are always hyperpolarizing. The action potential always moves in one direction along an axon. Integration of sensory information is a major function of the central nervous system. All axons in the body are myelinated.
What is a nerve impulse? State the direction followed by a nerve impulse while travelling in the body of an organism.
