Questions
1. When you are very nervous, perhaps before you must speak in front of your college class, you notice that your mouth is dry and your heart is racing. This is most likely due to stimulation by the
somatic division of your sympathetic nervous system.
motor division of your sympathetic nervous system.
sympathetic division of your autonomic nervous system.
parasympathetic division of your autonomic nervous system.
2. Sensory input is one of the nervous system's interconnected functions that
involves conveying signals from the CNS to effector cells.
conducts signals from integration centers.
conducts signals from sensory receptors to integration centers.
interprets sensory signals and formulates responses.
3. In all vertebrates, the brain consists of the
cerebrum, cerebellum, and hindbrain.
forebrain, midbrain, and hindbrain.
cerebrum, midbrain, and hindbrain
cerebrum, forebrain, and hindbrain.
5. A physician friend of yours is telling you about a patient with a head injury who suddenly stopped breathing. Your friend explains that the bony rim was pressing against the breathing center. You guess that the "bony rim" (whatever that is) must have been exerting pressure in the region of the
thalamus and hypothalamus.
spinal column of the upper back.
medulla oblongata and pons.
cerebellum and cerebrum.
6. Which of the following statements regarding the peripheral nervous system is true?
The spinal cord is part of the peripheral nervous system.
The brain is part of the peripheral nervous system.
Nerves are part of the peripheral nervous system.
Spinal nerves contain either sensory or motor axons, but not both.
7. The two major anatomical divisions of the nervous system are the
sympathetic nervous system and parasympathetic nervous system.
the autonomic and somatic nervous system
central nervous system and peripheral nervous system.
sensory nervous system and motor nervous system.
8. Which of the following statements regarding the nervous system is true?
Interneurons integrate data and relay appropriate signals to receptors.
Motor neurons convey signals from the CNS to effector cells.
The CNS and the brain are the same thing.
Sensory neurons convey signals from the CNS to sensory receptors.

Olfaction is the sense that enables organisms to distinguish and interpret odors. An action potential is initiated when a chemical interacts with an odor-receptor protein in the cell of a sensory neuron in the nasal cavity.
9. The part of the brain where odors are interpreted
hypothalamus
cerebrum
cerebellum
medulla oblongata
10. Saltatory conduction refers to which of the following?
The conduction of an action potential along a cell body
The conduction of an action potential along a dendrite
The conduction of an action potential along a myelinated axon.
The conduction of an action potential along a unmyelinated axon.
Use the following information to answer the next question
Acupuncture has been used in Chinese medicine for thousands of years as a treatment for chronic pain and other ailments. Acupuncture increases the level of endorphin in the central nervous system. Endorphins affect the part of the brain that interprets pain stimuli. Acupuncture also affects the part of the brain that interacts with the endocrine system in the maintenance of homeostasis.
11. The part of the brain that is affected by acupuncture in the treatment of ailments involving endocrine control is the
medulla oblongata
cerebrum
hypothalamus
cerebellum
12. The sophisticated behavior of mammals and birds is directly related to
the presence of a forebrain.
their relatively large cerebrum.
the presence of a midbrain.
the presence of a hindbrain.
13. Which division of the human nervous system carries signals to skeletal muscles?
somatic nervous system
sympathetic nervous system
autonomic nervous system
parasympathetic nervous system
Use the following information to answer the next question
Exposure to certain foods or environmental agents can cause a severe allergic reaction known as anaphylaxis. Common symptoms of anaphylaxis include a decrease in blood pressure and constriction of bronchioles in the lungs.
14. The division of the nervous system that produces effects most similar to those of anaphylaxis is the
parasympathetic nervous system, which is part of the somatic nervous system
sympathetic nervous system, which is part of the somatic nervous system
sympathetic nervous system, which is part of the autonomic nervous system
parasympathetic nervous system, which is part of the autonomic nervous system
15. The central communication conduit between the brain and the rest of the body is the
nervous system.
spinal cord.
brain stem.
nerve bundle.
