which part of the brain is primarily involved in the production of speech?
Broca’s
Pyramidal decussation or motor decussation occurs in the:
medulla oblongata
which brain region is primarily responsible for processing auditory language?
Wernicke’s
the cerebellum contributes to which aspect of speech?
coordination and timing of speech movements
apraxia of speech primarily affects:
the ability to plan and coordinate speech movements
neural plasticity refers to:
the brain’s ability to form new connections after injury
this artery is responsible for providing blood supply to the primary motor cortex and is most often occluded in a stroke.
middle cerebral artery (MCA)
this intrinsic muscle of the larynx is innervated by the superior laryngeal nerve (SLN):
cricothyroid
which of the following intervention strategies is most appropriate for a child with speech sound disorders?
A. increasing sentence length
B. targeting specific phonemes using visual feedback
C. enhancing vocabulary
D. focusing on fluency techniques
B. targeting specific phonemes using visual feedback
feedback in speech production primarily involves:
auditory and sensory input during communication
which cranial nerve is most directly involved in the movement of the tongue?
CN XII (hypoglossal)
which neurological disorder is most likely to result in HYPOkinetic dysarthria?
parkinson’s disease
efferent
motor
exit
afferent
sensory
arrives
pyramidal
tracts (originate in CEREBRAL CORTEX) carry fibers to spinal cord/ brainstem
*Voluntary!!!!
extrapyramidal
tracts (originate in BRAINSTEM) carry fibers to spinal cord
*Involuntary & automatic!!!!
UMN
cerebral cortex/ brainstem
transmit nerve impulses from brain to lower motor neurons
LMN
found in brainstem/ spinal cord
transmit nerve impulses from upper motor neurons to muscles
brain to LMN
UMN
UMN to muscles
LMN
rostral
front, towards the nose
caudal
back, towards the tail
CNS
brain
spinal cord
PNS
all other nerves (that are not in brain/ spinal cord)
parasympathetic
controls body functions at rest
sympathetic
fight or flight
autonomic
involuntary
cardiac and smooth muscles, glands
somatic
voluntary
skeletal muscles
included in peripheral nervous system:
automatic & somatic
automatic -> sympathetic & parasympathetic
included in central nervous system:
brain & spinal cord
brain -> forebrain, midbrain, and hindbrain
forebrain -> telencephalon & diencephalon
midbrain -> mesencephalon
hindbrain -> metencephalon & myelencephalon
medulla
lower portion of brainstem, below pons
regulates respiration, heart rate + reflexes
basal ganglia
deep within cerebral hemispheres
fine-tunes voluntary body movements, motor coordination, posture
thalamus
top of brainstem
relay center for sensory / motor signals
