- A. limbic system
- B. parasympathetic nervous system.
- C. autonomic nervous system
- D. central nervous system
Explanation: The autonomic nervous system carries involuntary messages to organs such as the heart; its sympathetic and parasympathetic branches…
Correct answer: autonomic nervous system- A. epinephrine
- B. insulin
- C. serotonin
- D. acetylcholine
Explanation: A threatening accusation activates the sympathetic fight-or-flight response, causing the adrenal glands to release epinephrine into the…
Correct answer: epinephrine- A. cerebellum
- B. peripheral nervous system
- C. sensory cortex
- D. reticular formation
Explanation: Sensory neurons carry information from receptors toward the central nervous system and therefore belong to the peripheral nervous system.
Correct answer: peripheral nervous system- A. corpus callosum
- B. sympathetic nervous system
- C. somatic nervous system
- D. cerebellum
Explanation: A racing heart, agitation, and jitteriness are typical effects of sympathetic nervous system activation, the arousing branch of the…
Correct answer: sympathetic nervous system- A. reduced levels of the neurotransmitter GABA
- B. increased activity at norepinephrine synapses
- C. excess levels of the neurotransmitter dopamine
- D. reduced activity at norepinephrine
Explanation: Major depression has traditionally been associated with reduced activity of monoamine systems, including norepinephrine, although its…
Correct answer: reduced activity at norepinephrine- A. tomography
- B. hemispherectomy
- C. phrenology
- D. plasticity
Explanation: Brain plasticity is the capacity of neural tissue to reorganise and for one area to assume functions formerly carried out by a damaged…
Correct answer: plasticity- A. dendrites to cell body to synapse
- B. axon to soma to dendrites
- C. dendrites to soma to axon
- D. glia to dendrites to axon
Explanation: Within a neuron, signals are typically received by the dendrites, integrated in the soma or cell body, and transmitted along the axon…
Correct answer: dendrites to soma to axon- A. understanding what others are saying
- B. recognizing familiar faces
- C. pronouncing words correctly
- D. controlling voluntary muscles
Explanation: Wernicke’s area supports comprehension of spoken and written language, so damage makes it difficult to understand what others say.
Correct answer: understanding what others are saying- A. epinephrine
- B. dopamine
- C. norepinephrine
- D. acetylcholine
Explanation: Acetylcholine activates skeletal muscles at the neuromuscular junction, producing voluntary movement and muscle contraction.
Correct answer: acetylcholine- A. pons
- B. positrons
- C. connector neurons
- D. hemispheres
Explanation: The cerebral cortex is divided into two cerebral hemispheres, the left and right, which communicate through the corpus callosum.
Correct answer: hemispheres- A. collection of sexual characteristics regulated by the X and Y chromosomes
- B. range of traits that contribute to reproductive success
- C. set of genetic material in an organism's chromosomes
- D. set of dominant traits received from either parent
Explanation: The genome is the complete set of genetic material present in an organism, including genes and other DNA in its chromosomes.
Correct answer: set of genetic material in an organism's chromosomes- A. arms
- B. legs
- C. trunk
- D. face
Explanation: The motor cortex gives disproportionately large areas to body parts requiring precise control, especially the face, hands, and fingers.
Correct answer: face- A. facially express emotions
- B. solve arithmetic problems
- C. understand simple verbal requests
- D. process information in an orderly sequence
Explanation: The right hemisphere contributes strongly to emotional expression and the interpretation of emotional information, so damage may impair…
Correct answer: facially express emotions- A. reticular formation
- B. autonomic nervous system
- C. endocrine system
- D. cerebral cortexGet Study Guides
Explanation: Hormones are chemical messengers released by glands into the bloodstream, which is the defining function of the endocrine system.
Correct answer: endocrine system- A. hypothalamus
- B. corpus callosum
- C. cerebellum
- D. medullaDiscover Lesson Plans
Explanation: The finger-to-nose task tests coordination and precision, functions controlled by the cerebellum, which alcohol commonly depresses.
Correct answer: cerebellum- A. axon
- B. cell body
- C. soma
- D. neurilemma
Explanation: The axon is the neuron's long conducting fiber, carrying electrical impulses away from the cell body toward other neurons or muscles.
Correct answer: axon- A. dendrite
- B. axon
- C. myelin
- D. soma
Explanation: The cell body is called the soma, which contains the nucleus and supports the neuron's metabolic functions.
Correct answer: soma- A. axons
- B. axles
- C. atoms
- D. axes
Explanation: The standard basic parts of a neuron are dendrites, the soma or cell body, and axons. Axles, atoms, and axes are not neuron structures.
Correct answer: axons- A. Axon
- B. Myelin
- C. Blastula
- D. Soma
Explanation: A blastula is an early stage of embryonic development, not a neuron structure. Axons, myelin, and the soma are all associated with neurons.
Correct answer: Blastula- A. form a protective coating over nerve axons
- B. affect the speed nerve impulses
- C. block the reception of acetylcholine
- D. aid a nerve's receptivity to neurotransmitters by increasing the number of receptor sites available
Explanation: Myelin forms an insulating protective sheath around many axons, allowing nerve impulses to travel more efficiently and rapidly.
Correct answer: form a protective coating over nerve axons
