COG - Final Flashcards
two main types of cells in the nervous system
glial cells
neurons
At the cellular level, information is transmitted in the nervous system by the conversion of what kind of energy?
electrical energy into chemical energy and then back into electrical
chemical cellular communication happens at the?
synaptic cleft
what does the neurotransmitter do?
chemical messengers that transmit a message from a nerve cell across the synapse to a target cell
What are the divisions of the nervous system?
Central nervous system (CNS)
Peripheral nervous system (PNS)
What two structures make up the central nervous system?
Brain
spinal cord
Divisions of the peripheral nervous system
somatic nervous system (SNS)
autonomic nervous system (ANS)
What are the outer coverings of the brain?
Dura mater, arachnoid membrane, pia mater
The main components/structures in the brain include what?
Cerebrum (lobes)
cerebellum
subcortical structures
brainstem
Grey matter is grey because it consists of
densely packed cell bodies
Name the 5 lobes of the brain
frontal temporal parietal occipital insula
Although there may be involvement across multiple lobes of the brain for cognition, the main lobe is believed to be the
frontal lobe
Which cortex of the frontal lobe is typically associated with executive function?
Prefrontal cortex
If you were to experience agnosia, or inability to recognize objects, this would likely be due to damage to the __ lobe of the brain.
Parietal
Visual processing is believed to be involved with the __ lobe of the brain.
Occipital
Balance is typically associated with this part of the brain
Cerebellum
The brain’s subcortical structures include?
thalamus hypothalamus pituitary gland hippocampus basal ganglia amygdala
The subcortical structure believed to form and store memories associated with emotional events is the
amygdala
The three parts of the brainstem from superior to inferior are the
midbrain
pons
medulla
The portion of the midbrain that produces the neurotransmitter dopamine is the
substantia nigra
T/F: Efferent nerves travel from the CNS to the body
True
T/F: Afferent nerves travel from the CNS to the body
False
Which type of tracts in the CNS provide intrahemispheric connection?
Association
The two arterial systems in the brain are __ arteries, which provide posterior blood circulation, and the __ arteries, which provide anterior circulation
Vertebral; carotid
T/F: SLPs do not need to be familiar with neurology to be effective
False
Cognition is an umbrella term for all higher mental processes including:
(LAME)
language
attention
memory
executive function
According to Solhberg & Mateer (1987, 2001, 2010), the two broad component types of attention are
executive control of attention
sustained
The four types of attention under executive control are
selective
alternating
suppression
working memory
Listening to a spoken passage in the presence of background noise requires intact attention of what kind?
Selective
The areas of the brain that are devoted to attention are
frontal lobe
temporal lobe
parietal lobe
__, __, and __ __ are the various stages of information processing described by the Stages Model of human memory
encoding
storage
retrieval process
Delayed recall is associated with which state of human memory?
Retrieval
The early processing of material to be learned is associated with which stage of human memory?
encoding
As an SLP, your evaluation should include these parts
case history
physical exam
assessments
Give an example of vascular disease
cerebrovascular disease (stroke)
T/F: Presence/absence of impairment can be made using results of a single cognitive communication measure
False
List all types of executive functioning
Initiation planning judgment metacognition mental flexibility problem solving inhibition reasoning self-regulation
What area within the frontal lobe is believed to be most involved with executive function?
prefrontal cortex
Name a brain area believed to be important for the storage of new memories
hippocampus
temporal lobe
The memory retrieval process is believed to be mediated by the __ lobe and subcortical structures
frontal
Data collected on an individual client is a type of __ evidence
internal
The 2 types of treatment are rehabilitative and __
compensatory
T/F: A screen is used to identify presence of impairment and is usually a pass/fail.
True
What areas of the brain are most likely impacted when there is attention impairment?
temporal lobe
parietal lobe
frontal lobe
