chapter 11 Flashcards
What includes nuclei and tracts along the border between the CEREBRUM and the DIAENCEPHALON?
Limbic system
The limbic system is a functional grouping rather than an anatomical one. it includes portions of the…
1) Cerebrum
2) diencephalon
3) mesencephalon
while the sensory cortex, motor cortex, and association areas of the cerebral cortex enable an individual to perform complex tasks, it is largely the ________________ that makes the individual want to do them
limbic system
There are strong connections of the limbic system with other areas of the brain, especially the ______________
hypothalamus
what are the functions of the limbic system?
1) establishing EMOTIONAL STAGES
2) facilitating memory STORAGE and retrieval
3) linking the conscious, intellectual functions of the cerebral cortex with the unconscious and autonomic functions of the BRAINSTEM
What are the structures of the limbic system?
1) CINGULATE GYRUS
2) SEPTAL NUCLEI
3) PARAHIPPOCAMPAL GYRUS
4) these structures border the corpus callosum and the rostral brainstem
What are the two key functional centers of the limbic system?
1) AMYGDALA
2) hippocampus
What lies SUPERIOR to the corpus callosum. it is responsible for:
1) Focusing attention on EMOTIONALLY significant events
2) Association memories to scents and pain
3) Executive functioning
4) Respiratory control
Cingulate gyrus
What are located in the SEPTUM PELLUCIDUM
Septal nuclei
What have extensive communications with other parts of the limbic system and brain
Septal nuclei
What are associated with PLEASURE and REWARD
Septal nuclei
Damage to this area results in avoidance to stimulation?
Septal nuclei
What is located along the periphery of the hippocampus?
Parahippocampal gyrus
What is involved in MEMORIES and the RETRIEVAL of memories, with a focus on the RECOGNITION of LOCATIONS AND SCENES?
Parahippocampal gyrus
What is located at the tail end of caudate nucleus? it is a CEREBRAL contribution to the limbic system
Amygdala (amygdala bodies)
What appears to act as an INTERFACE between the limbic system, cerebrum, and various sensory systems
amygdala
What plays a role in drive-related behaviors, the perception and expression of emotions, and LINKING EMOTIONS with specific MEMORIES
Amygdala
Damage to this area results in behavioral changes, especially a loss of fear or a decrease in emotional excitability
Amygdala
What resembles the shape of a seahorse, plays an important role in LEARNING AND MEMORY?
Hippocampus
damage to this area results in an inability to learn and the loss of SHORT TERM MEMORY
Hippocampus
What transmits impulses between the areas associated with the limbic system?
Fornix
Damage to this area results in disturbance to the areas that it connects, which results in decrease memory formation and recall
Fornix
What part of the limbic system process sensory information, which includes OLFACTORY sensations?
Mammillary bodies
Damage to this area results in an uncontrolled ORAL FIXATION on different objects, such as licking money?
Mammillary bodies
Other nuclei of the limbic system include what, this is associated with the hypothalamic center that are responsible for emotions of rage, fear, pain, sexual arousal, and pleasure?
Anterior nucleus of the thalamus
Which is incorrect?
a) the limbic system is an anatomical group
b) the limbic system includes portions of the cerebrum, diencephalon, and mesencephalon
c) limbic system includes nuclei and tracts along the border between cerebrum and the diencephalon
d) there is a strong connection between the limbic system and the hypothalamus
a) the limbic system is an anatomical group
All of the following are functions of the limbic system except:
a) responsible for the drive and motivation to perform tssks
b) establish emotional states
c) facilitates memory storage and memory retrieval
d) Link the conscious, intellectual functions of the cerebral cortex with the unconscious and autonomic functions of the midbrain
d) link the conscious, intellectual function of the cerebral cortex with the unconscious and autonomic functions of the midbrain
Question 3) Which is correct?
a) The limbic lobe consists of 4 structures
b) The congulate gyrus is lateral to the corpus callosum
c) The structures of the limbic lobe border the corpus callosum and the rostral brainstem
d) Dysfunction of the septal nuclei may result in schizophrenia or depression
c) The structures of the limbic lobe border the corpus callosum and the rostral brainstem
Question 4) the key functional center of the limbic system include all except:
a) Hippocampus
b) Amygdala
c) Amygdaloid body
d) Fornix
d) Fornix
Question 5) Which is correct?
a) Septal nuclei are associated with pleasure and reward
b) The parahippocampal gyrus plays a role in drive-related behaviors
c) Damage to the fornix may result in an uncontrollable oral fixation on different objects, such as licking money
d) The hippocampus appears to act as an interface between the limbic system, cerebrum, and various sensory systems
a) Septal nuclei are associated with pleasure and reward
