The most probable location of the lesion is the: left primary somatosensory cortex right parietal association cortex Broca's area left cortex right prefrontal cortex

thalamus and parietal cerebral cortex
Cutaneous two-point discrimination requires: thalamus and cranial nerve XI accesssory thalamus and frontal cerebral cortex thalamus and parietal cerebral cortex hypothalamus and parietal cerebral cortex
True
Gray matter consists predominantly of neuron cell bodies and dendrites. True False
thalamus
In which of the following areas do sorting and editing of sensory impulses take place? postcentral cortex thalamus hypothalamus prefrontal cortex basal nuclei
False
Most central nervous system axons are able to regenerate following injury. True False
True
Most nerves are able to transmit impulses both to and from the central nervous system. True False
pain
Nociceptors advise the brain of ___________. temperature chemicals in solution pain light
True
Only the brain interstitial fluid (not the blood or CSF) comes into direct contact with the neurons and glial cells. True False
Only the brain interstitial fluid - NOT BLOOD OR CSF - comes into direct contact with the neurons and glial cells. The composition of the brain interstitial fluid is critical
So, what specifically nourishes neurons and neural cells? Blood? CSF? Brain interstitial fluid?
True
Spatial discrimination is the ability to identify the specific region of the body being stimulated. True False
primary somatosensory
The ______________________ cortex resides in the postcentral gyrus of the parietal lobe, just posterior to the primary motor cortex. Neurons in this gyrus receive information from the general (somatic) sensory receptors in the skin and from proprioceptors (position sense receptors) in skeletal muscles, joints, and tendons. The neurons then identify the body region being stimulated, which is an ability called spatial discrimination. auditory association primary somatosensory limbic prefrontal

False
The amount of cortical space in the primary motor cortex devoted to a given body part is proportional to the size of the part. True False
False
The basal nuclei play an important inhibitory role in sensory control. True False
True
The cerebellum and basal nuclei both help coordinate voluntary movements, but neither of these brain regions directly stimulate motor neurons. True False
True
The hippocampus is a critical site for converting short-term memories into long-term memories. True False
False
The occipital lobe is in the posterior region of the brain and houses the auditory cortex. True False
perceives pain, temperature, touch, pressure, conscious proprioception
The primary somatosensory cortex: is located in the occipital lobe controls homeostasis is located in the frontal lobe perceives pain, temperature, touch, pressure, conscious proprioception
perceives pain, temperature, touch, pressure, conscious proprioception
The primary somatosensory cortex: perceives pain, temperature, touch, pressure, conscious proprioception controls homeostasis is located in the frontal lobe is located in the occipital lobe
corpus callosum
The structure of the cerebrum that functionally and anatomically connects the two hemispheres is called the: corpus callosum superior colliculi thalamus hypothalamus
true
The two regions of gray matter within the cerebrum are the cerebral cortex and the basal nuclei. True False
parietal
Two point discrimination is processed in the __________ lobe. temporal occipital frontal parietal
hypothalamus
What part of the limbic system controls the increase of heart rate and respiratory rate, elevation of blood pressure, and diversion of blood to skeletal muscles? thalamus hippocampus hypothalamus amygdala pineal gland
superior colliculi
Which of the following areas is NOT involved in speech processing? auditory association area Broca's area Wernicke's area superior colliculi
It allows us to tie information that we receive to previous experience and knowledge and then helps us decide what action to take.
Which of the following best describes the multimodal association cortex? It permits the perception of sound stimuli and stores them for future reference. It integrates sensory input to produce understanding of an object being felt. It allows us to tie information that we receive to previous experience and knowledge and then helps us decide what action to take. It regulates our heart and other involuntary muscles in response to environmental stimuli.

The nervous system processes and interprets sensory input and decides what should be done at each moment.
Which of the following best describes the nervous system function of integration? The nervous system uses its millions of sensory receptors to monitor changes occurring both inside and outside the body. The nervous system causes a response by activating effector organs, such as the muscles and glands. The nervous system processes and interprets sensory input and decides what should be done at each moment. The nervous system generates neurons in order to replace or repair damaged neurons; this permits optimal communication between the CNS and the body's effector organs.
superior colliculi
Which of the following coordinate head and eye movements when we visually follow a moving object? red nucleus pneumotaxic center superior colliculi inferior colliculi
solving math problems
Which of the following is (are) dominated by the left cerebral hemisphere? artistic creativity solving math problems intuitive thought understanding jokes
balance
Which of the following is NOT a function of the hypothalamus? food intake regulation balance autonomic control body temperature regulation regulation of sleep-wake cycles

Which of the following is NOT one of the three basic regions of a cerebral hemisphere? he internal white matter the diencephalon the superficial cortex of gray matter the basal nuclei
