Example Question #1 : Help With Brain Physiology
What region in the brain may have been damaged if a person has trouble understanding language?
Amygdala
Wernicke's Area
Hippocampus
Hypothalamus
Broca's area
Wernicke's Area
Receptive aphasia, the inability to understand language, is caused by ischemia to Wernicke's area. Wernicke's area is essential to incorporation of language and understanding. In contrast, Broca's area is used in language formation and speech. Someone with expressive aphasia, the inability to form words, has had damage to Broca's area in the inferior frontal gyrus.
The hippocampus is located in the temporal lobe and is responsible for memory formation. The amygdala is located in the brain interior and is responsible for aggression and libido. The globus pallidus is a subcortical structure that is responsible for initiating voluntary movement.
Example Question #62 : Neural Physiology
An unsteady gait or off-balance feeling could indicate that what part of the brain is being affected?
Occipital lobe
Parietal lobe
Cerebellum
Temporal lobe
Frontal lobe
Cerebellum
The cerebellum, located inferoposterior to the cerebrum, is the portion of the brain that controls balance and coordinated muscle movements.
The frontal, parietal, temporal, and occipital lobes are all regions of the cerebrum. Each lobe is associated with different types of processing. The frontal lobe helps with motor integration and conscious thought. The temporal lobe is associated with memory and auditory integration. The parietal lobe is responsible for somatosensory inputs. The occipital lobe houses the visual cortex.
Example Question #71 : Neural Physiology
Which portion of the brain is responsible for maintaining body temperature and signaling hunger?
Thalamus
Hypothalamus
Brain stem
Cerebellum
Hypothalamus
The hypothalamus is often called the thermostat of the body. In addition to controlling body temperature, it also controls hunger, thirst, and reproductive behaviors.
The thalamus controls sensory integration. The cerebellum is associated with balance and coordination. The brain stem monitors vital activity, such as circadian rhythm, heart rate, and respiration.
Example Question #72 : Neural Physiology
Which of the following brain structures is NOT correctly matched with its function?
Basal ganglia helps initiate voluntary movements and make postural adjustments
Cerebellum helps maintain posture and balance, muscle tone, and coordinate voluntary motor activity
Posterior pituitary regulates thirst and water balance
Thalamus is the major relay center for sensory information
Posterior pituitary regulates thirst and water balance
The posterior pituitary, or neurohypophysis, receives axons from the hypothalamus and secretes antidiuretic hormone (ADH) and oxytocin. The hypothalamus is responsible for regulation of thirst and water balance.
The other answer choices correctly match brain structures and functions.
Example Question #73 : Neural Physiology
Which of the following is not a role of the limbic system?
Spatial memory
Feeling and emotion
Aggression
Posture and balance
Posture and balance
The limbic system includes the cingulate gyrus, hippocampus, fornix, mammillary bodies, amygdala, and septal nucleus and is responsible for behavioral and emotional expression. This includes aggression, which is thought to originate from the amygdala. Spatial memory is located in the hippocampus, and is linked to behavioral expression.
The cerebellum controls posture, balance, muscle tone, and coordination of voluntary motor activity.
Example Question #74 : Neural Physiology
Which of the following structures is NOT part of the blood-brain barrier?
Astrocytes
Tight junctions between capillary endothelial cells
A basement membrane
Extensive smooth muscle around arterioles
Extensive smooth muscle around arterioles
The blood-brain barrier is formed by three key structures. Tight junctions between nonfenestrated capillary endothelial cells prevents fluid and solutes from diffusing out of the capillary, as they would in the periphery. A thick basement membrane provides another layer of separation. Astrocytes interact with capillaries to mediate nutrient transfer.
Though most arterioles are surrounded by layers of smooth muscle, only capillaries interface with the blood-brain barrier.
Example Question #75 : Neural Physiology
Which of the following structures secretes cerebrospinal fluid (CSF)?
Cisterna chyli
Pineal gland
Choroid plexus
Adrenal cortex
Choroid plexus
The choroid plexus is a specialized region within the walls of each of the four ventricles in the brain that secretes CSF. Cisterna chyli is a part of the thoracic duct of the lymphatic system, and receives chyle from the intestines. The adrenal cortex and pineal gland secrete hormones, not CSF.
Example Question #1 : Help With Brain Physiology
Which cranial nerve is known as "the wanderer?"
I
V
X
II
X
Cranial nerve X is also known as the vagus nerve. It is called "the wanderer" because it wanders from the brain stem through the neck, chest, and abdomen. Cranial nerve II is known as the optic nerve. Cranial nerve I is the olfactory nerve and cranial nerve V is the trigeminal nerve. None of the other cranial nerves exit the cranium.
Example Question #76 : Neural Physiology
What structure in the brain maintains vital body functions such as heart rate and breathing?
Medulla
Cerebrum
Broca's area
Pons
Medulla
The Medulla, also known as the medulla oblongata, is located in the brainstem and is responsible for maintaining vital body functions, most notably control of respiratory rate and heart rate. The pons is responsible for relaying information between the forebrain and the cerebellum. The cerebrum integrates complex sensory and neural functions. Broca's area is responsible for generating speech.
Example Question #77 : Neural Physiology
For what is the "little brain" responsible?
Balance, posture, and coordination
Processes visual stimuli
Fight or flight response
Controls heart rate and breathing
Balance, posture, and coordination
The "little brain" is also known as the cerebellum. The Cerebellum is responsible for allowing people to maintain their posture and ability to move effectively. The occipital lobe processes visual stimuli, the medulla controls heart rate and breathing, and the flight or fight response is mediated by the amygdala.
