Example Question #251 : Systems Physiology
What is the name of the bundle of fibers that connects Wernicke's area to Broca's area?
Corpus collosum
Aqueduct of Sylvius
Central sulcus
Lateral sulcus
Arcuate fasiculus
Arcuate fasiculus
The bundle of fibers that connects Wenicke's area with Broca's area is called the arcuate fasiculus. Broca's area is located in the frontal lobe and Wernicke's area is located in the temporal lobe. The corpus callosum is a band of nerve fibers that connects the left and right hemispheres of the brain. The Aqueduct of Sylvius is a canal which cerebrospinal fluid flows between the third and fourth ventricles of the brain. The lateral sulcus is a prominent structure in the brain which divides the frontal lobe and parietal lobe (above) from the temporal lobe (below), while the central sulcus separates the frontal lobe from the parietal lobe.
Example Question #252 : Systems Physiology
Knowing how to ride a bike is an example of what type of memory?
Declarative memory
Working memory
Procedural
Short-term
Immediate
Procedural
Knowing how to ride a bike is an example of procedural memory. Procedural memory is involved in learning motor skills. Working memory can be another name for immediate memory, which means lasts a few seconds to a few minutes, such as temporarily remembering a set of numbers. Declarative memory includes short-term memory and is concerned with people, events, occurrences, and facts.
Example Question #253 : Systems Physiology
The "biological master clock" or regulation of sleep-wake cycle is controlled by what structure of the brain?
Thalamus
Cerebellum
Thyroid
Hypothalamus
Basal ganglia
Hypothalamus
The hypothalamus (part of the diencephalon) is responsible for maintaining the sleep-wake cycle and regulating the "biological clock". These are set by a specific nuclei located in the hypothalamus, the suprachiasmatic nucleus. The thalamus is also part of the diencephalon but is primarily involved in relaying sensory and motor signals through the cerebral cortex. The thyroid is an endocrine gland which secretes thyroid hormones that regulate metabolism, growth and development, and temperature. The cerebellum coordinates muscle activity and the basal ganglia aids in coordinating movement. The epithalamus contains the pineal gland, which may play a role in the sleep-wake-cycle (circadian rhythm) via the hormone melatonin.
Example Question #254 : Systems Physiology
The cerebellum is responsible for which of the following functions?
Vision
Hearing and memory
Coordinated body movement and muscle memory
Sensory
Executive functioning and personality
Coordinated body movement and muscle memory
The cerebellum plays an important role in motor control. The cerebellum does not initiate movement, but it is important in coordination, precision, and accurate timing of movements. The cerebellum receives and integrates input from the sensory systems from the spinal cord and other parts of the brain to fine tune motor activity.
The parietal lobe is important in sensory integration, visuaospatial processing, and the manipulation of objects. The frontal lobe is responsible for conscious thought and executive functioning; damage to the lobe can result in mood and personality changes. The occipital lobe is responsible for sight; damage to the area can produce hallucinations and blindness. The temporal lobe is involved in the sense of smell and sound, it also plays a role in processing complex stimuli such as faces and scenes and memory.
Example Question #255 : Systems Physiology
The brainstem is directly responsible for which of the following functions?
Executive functioning
Respiration, circulation, digestion
Sensory integration
Body movement and coordination
Speech production
Respiration, circulation, digestion
The brainstem consists of the midbrain, pons, and medulla oblongata. The brainstem continues inferiorly to become the spinal cord. The brainstem is responsible for basic living functions, including but not limited to: respiration, circulation (including heart rate), and digestion. As such, any injury to the brainstem would be catastrophic. Additionally ten of twelve cranial nerves pass through the brainstem, going on to provide the face and neck with motor and sensory functions. Furthermore, nerve conduction of the motor and sensory systems of the brain and body pass through the brain stem including the corticospinal tract (involved in motor activity), the posterior column-medial lemniscus pathway (involved in fine touch, vibration sensation, and proprioception), and the spinothalamic tract (involved in pain, temperature, itch, and crude touch).
Example Question #256 : Systems Physiology
The frontal lobe of the cerebrum is responsible for which of the following functions?
Breathing, circulation, and digestion
Hearing and memory
Vision
Executive functioning and personality
Integration of sensation
Executive functioning and personality
The cerebrum consists of four lobes: the frontal, temporal, parietal, and occipital. Some sources also include the limbic lobe (responsible for emotion and memory) and the insular cortex (responsible for pain). The frontal lobe is responsible for conscious thought and executive functioning; damage to the lobe can result in mood and personality changes. The parietal lobe is important in sensory integration, in visuaospatial processing, and the manipulation of objects. The occipital lobe is responsible for sight; damage to the area can produce hallucinations and blindness. The temporal lobe is involved in the sense of smell and sound, memory, and it also plays a role in processing complex stimuli such as faces and scenes.
The cerebellum is responsible for coordinated body movements and muscle memory. The brainstem allows for breathing, circulation, heart rate, and digestion.
Example Question #257 : Systems Physiology
The parietal lobe of the cerebrum is responsible for which of the following functions?
Vision
Sensory integration
All of these
Executive functioning and personality
Hearing and memory
Sensory integration
The cerebrum consists of four lobes: the frontal, temporal, parietal, and occipital. Some sources also include the limbic lobe (responsible for emotion and memory) and the insular cortex (responsible for pain). The parietal lobe is important in sensory integration, visuaospatial processing, and the manipulation of objects. The frontal lobe is responsible for conscious thought and executive functioning; damage to the lobe can result in mood and personality changes. The occipital lobe is responsible for sight; damage to the area can produce hallucinations and blindness. The temporal lobe is involved in the sense of smell and sound, it also plays a role in processing complex stimuli such as faces and scenes and memory.
Example Question #258 : Systems Physiology
Where is cerebrospinal fluid (CSF) made?
Dural venous sinuses
Cerebral aquaduct
Arachnoid granulations
Choroid plexus
Cerebral ventricles
Choroid plexus
CSF is a clear, colorless body fluid found in the subarachnoid space of the brain and spine that acts as a cushion for the brain. In addition to mechanical protection, CSF also provides immunological protection to the brain. CSF is made in the choroid plexus of the brain’s ventricles. Approximately 500 mL of CSF are made daily, however due to constant reabsorption, only about 100-160 mL are present at a given moment.
Example Question #259 : Systems Physiology
Where is cerebrospinal fluid (CSF) reabsorbed?
Superior vena cava
Cerebral ventricles
Choroid plexus
Arachnoid granulations
Thoracic duct
Arachnoid granulations
CSF is a clear, colorless body fluid found in the subarachnoid space of the brain and spine that acts as a cushion for the brain. In addition to mechanical protection, CSF also provides immunological protection to the brain. CSF is made in the choroid plexus of the brain’s ventricles. Approximately 500 mL of CSF are made daily, however due to constant reabsorption, only about 100-160 mL are present at a given moment.
CSF is returned to the vascular system by entering the dural venous sinuses through arachnoid granulations. Some have suggested that CSF flows along the cranial nerves and spinal nerves into lymphatic channels.
Example Question #260 : Systems Physiology
The hypothalamus is responsible for which of the following functions?
A relay station for information
Breathing, circulation, and digestion
Homeostasis, including body temperature and circadian rhythms
Vision
Body movement, coordination, and muscle memory
Homeostasis, including body temperature and circadian rhythms
The hypothalamus is located below the thalamus, just above the brainstem and controls body temperature, hunger, thirst, fatigue, and circadian rhythms.
The thalamus can be thought of as a relay station for sensory and motor signals to and from the cerebral cortex. The brainstem is responsible for breathing, circulation, and digestion. The cerebellum plays an important role in coordination of body movements and muscle memory.
