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
