Chapter 14 Homework
The _________ is most likely to be stimulated first upon hearing a spoken word
primary auditory cortex
What type of brain wave would characterized the EEG of a student taking a calculus exam?
Beta
Nonfluent aphasia, due to a lesion in the __________, results in slow speech, difficulty in choosing words, or use of words that only approximate the correct word.
Broca area
During lecture, a student is awake, but in a quiet resting state with his eyes closed. His EEG pattern is likely dominated by ______________ waves
alpha
A nurse is caring for a patient who exhibits the following symptoms: - inability to maintain balance while walking - normal intelligence - can initiate voluntary movements although they are somewhat uncoordinated - decreased tone in the skeletal muscles The patient is probably suffering from a condition that affected the
cerebellum
An electroencephalogram obtained from an adult in stage 4 sleep would likely display an abundance of ____________
delta waves
If you decide to "snap your fingers," the first neurons to be stimulated are the
motor neurons in the premotor area
A major source of sensory input into the limbic system is the sense of
smell
During rapid eye movement (REM) sleep
the muscles are paralyzed, and body temperature, blood pressure, and heart and respiratory rates increase.
The primary somatosensory area is located in
the postcentral gyrus
Wernicke area is necessary for
understanding and formulating coherent speech
Brain regions involved in memory
-hippocampus -temporal lobes -cerebellum -amygdala - brain structures involved in perception -limbic system -frontal cortex
Match the brain wave pattern with the correct description
1. Alpha Waves: occur during a quiet, resting state with the eyes closed 2. Beta Waves: Occur during intense mental activity 3. Theta Waves: Occur in children or adults that are frustrated 4. Delta Waves: Occur in infants and in deep sleep
Match each function with the correct area on the cerebral cortex
1. Visual Processing: Occipital lobe 2. Taste Perception: Insula 3. Odor Perception: Inferior temporal lobe 4. Auditory Processing: Superior Temporal Lobe
Match the type of memory with its example
Long-Term: Used when you take the final exam for this course Working Memory: Used when you give yourself a short mental list for groceries, just before writing them down Short-Term: Used when you recall your lost of grocery items because you left the list at home
Complete each sentence by dragging the proper term into the appropriate blank
Olfaction and hearing are processed in the TEMPORAL LOBES. The FRONTAL LOBE provides critical function in motivation, logical reasoning, expression of emotion, and social attitudes. Housing the visual centers, the OCCIPITAL LOBES receive inputs from the optic radiation. The frontal lobes also include the primary MOTOR COMPLEX, which controls voluntary motor functions. The PARIETAL LOBES exhibit receipt and association of general body sensations. The deepest of the cerebral lobes, the INSULA is also the smallest and least understood
T/F: The EEG of a normal, healthy brain exhibits mostly irregular patterns
True
A patient is asked to read a paragraph while the clinician recorded the brain activity on a PET scan. Which of the following brain regions would "light up" the most?
Wernicke Area
Commissures
extend between the right and left cerebral hemispheres
The reticular formation is an area of the brain that
has sensory and motor components
A baseball pitcher was hit on the side of the head by a line drive. When he was revived, he could not remember how many balls and strikes the batter had. This was because
he lost both working and short-term memory
The cerebellum functions as a comparator. This means that the cerebellum compares
intended movements with actual movements
The primary motor cortex for control of voluntary muscles is found in the
precentral gyrus of the frontal lobe
If a person decided to jump over a chair, the __________________ area would organize the motor functions needed to carry out this action
premotor area
The _____________ receives sensory input from a variety of stimuli and assists with the level of arousal and consciousness of the brain
reticular activating system
The cell bodies of ______________ are located in the cerebral cortex, and the cell bodies of ______________ are located in the anterior horns of the spinal cord gray matter and in the cranial nerve nuclei of the brainstem
upper motor neurons ; lower motor neurons
