Quizzes Flashcards
the study of the nervous systems function refers to
neurophysiology
describe the rationale behind studying neuroscience for speech language pathology and audiology
it allows us to speak the language of neurologists and help better communication, helps us choose appropriate testing, predict problems, documenting change/efficacy of treatment, and improves our knowledge of neuroplasticity.
t/f: peripheral nervous system includes brain and spinal cord
false
brain is the most important central structure in the human body
brain centrality
brain has the ability to reorganize brain tissue functions
brain plasticity
brain regions are interconnected and there is constant integration of information
brain interconnectivity
brain has a preferential organization of some functions into right-left side and with ipsilateral-contralateral control
brain laterality
brain has dedicated paths for processing different types of information and function
brain networking
a hollywood actor diagnosed with Parkinson’s disease and who is extremely involved in research for PD
Michael j fox
the structures in the cerebrum include all except the following: basal ganglia, limbic system, thalamus, medulla, cortex
medulla
what’s the difference between gyrus and sulcus
gyrus is a fold or bump on the surface of the brain
sulcus is a depression on the surface of the brain
the numbering system used by neuroscientists to denote different areas in the cortex is called
brodmann classification
whats the difference between primary and secondary areas in the cortex
primary areas receive and send the information the the secondary
secondary areas interpret the information
primary motor area is located in the precentral gyrus of the
frontal lobe
primary somatosensory area is located in the post central gyrus of the
parietal lobe
a common language impairment associated with damage to left frontal lobe is
brocas aphasia
neuronal cell bodies and supporting cells form layers in the brain called
gray matter
t/f: spinal cord is part of the cerebral cortex
false
lateral sulcus separates:
frontal from temporal lobe
human nervous system develops out of ___ layer
ectoderm
explain in your own words the steps involved in brain development
A: notochord: specialized cells induce the ectoderm cells to become the primitive nervous system
B: neural folds: neuroepithelium wrinkles and folds over
C: Neural tube: the precursor of the brain and spinal cord, the neural tube, is formed.
D: neural crest cells: cells migrate and initiate development of body structures
what structures emerge out of hindbrain
pons medulla cerebellum spinal cord
t/f: pruning actions eliminates redundant or improper neural connections to hone the specificity of remaining neural circuits
true
give one reason for left vs right interhemispheric asymmetries in human brain
molecular influences on gene regulation during fetal development
Insufficiency of _____________________ gene causes a severe speech and language disorder associated with morphological abnormalities and functional under activation of Broca’s area
FoxP2
the process of proliferation of myelin sheaths in the nervous system is referred to as
myelinogenesis
defective fusion of neural tube during brain development can lead to
anencephaly
CSF acronym
cerebrospinal fluid
