The hormonal and nervous systems are often compared because of their similar roles in the body. Which of the following statements about the two systems are true? 1. The nervous system relies only on electrical impulses to work. 2. Both the hormonal and nervous systems activate target structures. 3. The fastest responses in the body are produced by the nervous system. 4. Only the hormonal system relies on the activity of chemicals. 5. Parts of the hormonal system may be controlled by the central nervous system. A) 1, 2 and 4 B) 1, 2 and 5 C) 2, 3 and 4 D) 2, 3 and 5 E) 3, 4 and 5

Which statement best describes the difference in the effects of the nervous system and endocrine system in regulating body functions?

The nervous system transmits signals which allows for rapid and short-term responses, whereas the system uses hormones to communicate, resulting in slower but longer-lasting effects.

The behavior of animals is under the control ofA) the endocrine system.B) the nervous system.C) both the nervous system and the endocrine system.D) neither the nervous system nor the endocrine system

Which of the following statements about the parasympathetic nervous system is true?Group of answer choicesOne neuron carries information from the central nervous system to the target cells in the parasympathetic nervous system.The parasympathetic nervous system innervates skeletal muscles.The parasympathetic nervous system controls the fight-or-flight response.The parasympathetic nervous system uses norepinephrine as its sole neurotransmitter.The parasympathetic nervous system leaves the central nervous system via the cranial nerves and sacral spinal nerves.

Hormonal (endocrine) responses are slowly than nervous responsesfaster than nervous responses
