Example Question #1428 : Ap Psychology
Which of the following parts of the brain is responsible for maintaining our breathing and heart rate?
Cerebellum
Amygdala
Pons
Cerebrum
Medulla
Medulla
The "medulla," also known as the medulla oblongata, contains the respiratory, cardiac, and vasomotor centers of the brain; therefore, the medulla controls the autonomic functions. These functions include: breathing, heart rate, and blood pressure. We would be not be able to survive—not even for a minute—without a functioning medulla.
Example Question #1429 : Ap Psychology
Which part of the brain is responsible for secreting hormones that control our body temperature and circadian rhythm?
Sulcus
Corpus callosum
Hypothalamus
Gyrus
Prefrontal cortex
Hypothalamus
The "hypothalamus" is responsible for synthesizing and secreting neurohormones that stimulate the secretion of pituitary hormones. The hypothalamus controls many important bodily functions, including maintaining a healthy body temperature and circadian rhythm (i.e. our 24 hour internal cycle).
Example Question #1431 : Ap Psychology
Which part of the brain is chiefly responsible for auditory and olfactory processing?
Occipital lobe
Parietal lobe
Prefrontal lobe
Frontal lobe
Temporal lobe
Temporal lobe
The "temporal lobe" plays an important role in organizing sensory input, auditory information, and language production. All four major lobes of the brain (temporal, parietal, frontal, and occipital) are located in the cerebral cortex.
Example Question #1432 : Ap Psychology
Which of the following parts of the brain is most heavily involved with decision making processes?
Corpus callosum
Amygdala
Cerebral cortex
Fornix
Cerebral cortex
The "cerebral cortex" is the large, folded exterior portion of the cerebrum that contains the different lobes of the brain. This structure is responsible for memory, perception, and consciousness—among other things. The fornix and the amygdala are part of the limbic system and do not play a large role in higher level thought. Additionally, the corpus callosum is anatomically defined simply as the connections between the two hemispheres of the brain.
Example Question #1433 : Ap Psychology
The function of the parasympathetic nervous system is to __________.
initiate a "fight or flight" response
None of these
voluntarily contract skeletal muscle
activate a "rest and digest" response
activate digestion
activate a "rest and digest" response
The parasympathetic nervous system (PSNS) is responsible for activating "rest and digest" and returning the body to equilibrium after a fight or flight response. This is opposed to the sympathetic nervous system (SNS) that is involved in the "fight or flight" response. They are both branches of the autonomic nervous system (ANS) which involuntarily regulates function of internal organs.
Example Question #1434 : Ap Psychology
Which structure connects the left and right cerebral hemispheres of the brain?
Thalamus
Broca's area
Brainstem
Wernicke's area
Corpus callosum
Corpus callosum
The corpus callosum is a band of nerve fibers that connect the brain's left and right hemispheres together. It is the largest white matter structure in the brain, and allows valuable information to be shared across brain hemispheres.
Example Question #1435 : Ap Psychology
What neurotransmitter triggers muscle contractions?
Acetylcholine
Serotonin
Dopamine
Norepinephrine
Insulin
Acetylcholine
Acetylcholine is located at the neuromuscular junction, and it triggers muscle contraction in the body's cells. This neurotransmitter is most frequently found in neuronal cells in the central nervous system (CNS) and peripheral nervous system (PNS).
Example Question #1436 : Ap Psychology
Which of the following is a false statement about endorphins?
Endorphins are linked to pleasure centers in the body
Endorphins are hormones
Endorphins are linked to pain centers in the body
Endorphins are neurotransmitters
Endorphins act similar to opiate drugs
Endorphins are hormones
Endorphins are a type of neurotransmitters that are closely linked to pleasure and pain centers in the body. They are not hormones; hormones are chemical messengers that are secreted directly into the blood and travel through the body to various organs.
Example Question #1437 : Ap Psychology
After suffering a stroke localized to the cerebellum, one would exhibit which of the following symptoms ___________________.
inability to regulate heart rate
inability to comprehend speech
inability to coordinate movements and loss of balance
inability to produce articulate speech
inability to form new memories
inability to coordinate movements and loss of balance
The cerebellum is located near the base of the brain. Its major function is to coordinate movement and preserve balance. Damage to this area from a stroke will prevent an individual from coordinating their movements.
Example Question #1438 : Ap Psychology
What term describes the brain imaging modality that relies on magnetic fields and electrons?
CT Scan
EKG
MRI
MT Scan
EEG
MRI
An MRI is a brain imaging modality that relies on magnetic fields. Strong magnets redirect the electrons within the body to produce an image. MRIs provide useful imaging of the soft tissue structures of the brain, and can be key in finding tumors, bleeding, and other brain abnormalities.
