Flaccid dysarthria results from

A.

Upper motor neuron lesion
B.

Lower motor neuron
C.

Problem with basal ganglia circuitry
D.

Cellarbellar circuitry

Correct Answer
B. Lower motor neuron

Explanation
Flaccid dysarthria results from damage or dysfunction in the lower motor neurons. The lower motor neurons are responsible for carrying signals from the brain to the muscles involved in speech production. When these neurons are affected, it can lead to weakness, reduced muscle tone, and impaired coordination of the muscles involved in speech. This results in the characteristic symptoms of flaccid dysarthria, such as slurred speech, breathiness, and difficulty with articulation.

3.

Hyperkinetic and hypokinetic dysarthria results from problems with

A.

Cerebellar circuitry
B.

Extrapyramidal circuitry - basal ganglia
C.

Upper motor neuron lesions

Correct Answer
B. Extrapyramidal circuitry - basal ganglia

Explanation
Hyperkinetic and hypokinetic dysarthria are both motor speech disorders that result from problems with the extrapyramidal circuitry, specifically the basal ganglia. The extrapyramidal circuitry is responsible for regulating and coordinating voluntary movements, including speech. Dysfunction in this circuitry can lead to abnormal muscle movements and control, causing the characteristic speech impairments seen in these dysarthrias. The cerebellar circuitry is primarily involved in coordinating motor movements and is not directly related to dysarthria. Upper motor neuron lesions, on the other hand, can cause spastic dysarthria but are not specifically related to hyperkinetic or hypokinetic dysarthria.

What is true about apraxia?

A.

Therapy is totally useless
B.

Can occur without muscular weakness
C.

A child with apraxia can not learn

Correct Answer
B. Can occur without muscular weakness

Explanation
Apraxia is a neurological disorder that affects an individual's ability to perform purposeful movements, despite having intact muscles and coordination. This means that apraxia can occur without muscular weakness. Individuals with apraxia may struggle with activities such as speaking, writing, or even simple gestures. Therapy is an essential treatment approach for apraxia, as it can help individuals improve their motor planning and coordination skills. While apraxia can present challenges, it does not mean that a child with apraxia cannot learn.

What are the six sensory systems in the brain?

A.

Supplementary motor strip, motor strip, parietal lobe, articulate fasiculus, occipital lobe
B.

Visual system, olfactory, auditory, gustatory, somasthetic

Correct Answer
B. Visual system, olfactory, auditory, gustatory, somasthetic

Explanation
The correct answer includes the five sensory systems: visual system (related to vision), olfactory (related to smell), auditory (related to hearing), gustatory (related to taste), and somasthetic (related to touch and body position). These sensory systems are responsible for receiving and processing information from the environment and sending it to the brain for interpretation and response.

What do first order sensory neurons do?

A.

Project neurons located in the brain stem or spinal cord
B.

Project to cerebral cortex from thalamus, ipsilateral to primary sensory cortex
C.

Innervate the sense organ in PNS ipsilateral

Correct Answer
C. Innervate the sense organ in PNS ipsilateral

Explanation
First-order sensory neurons are responsible for transmitting sensory information from the sense organ to the central nervous system. They innervate the sense organ in the peripheral nervous system on the same side of the body (ipsilateral). This allows them to detect and transmit sensory stimuli such as touch, temperature, or pain to the brain or spinal cord for further processing and interpretation.

What do third order sensory neurons do?

A.

Project to cerebral cortex from thalamus, ipsilateral to primary sensory cortex
B.

Innervate the sensory organs in PNS ipsilateral
C.

Projection neurons located in brain stem, spinal cord, point of decussation, to thalamus

Correct Answer
A. Project to cerebral cortex from thalamus, ipsilateral to primary sensory cortex

Explanation
Third order sensory neurons project to the cerebral cortex from the thalamus, specifically to the primary sensory cortex on the same side of the body (ipsilateral). These neurons are responsible for relaying sensory information from the thalamus to the cerebral cortex, allowing for the perception and interpretation of sensory stimuli.

Vision can be changed in patients with stoke and TBI. In understanding the optic nerve what happens with the retina and the brain?

A.

Half of the retina crosses the midline at optic chaism and half remains ipsilateral
B.

Half the retina mixes with the olfactory nerve

Correct Answer
A. Half of the retina crosses the midline at optic chaism and half remains ipsilateral

Explanation
The optic nerve is responsible for transmitting visual information from the retina to the brain. In cases of stroke and traumatic brain injury (TBI), the optic nerve can be affected, leading to changes in vision. The optic chiasm is the point where the optic nerves from each eye intersect. At this point, half of the fibers from each optic nerve cross the midline, while the other half remains on the same side (ipsilateral). This arrangement allows for the integration of visual information from both eyes in the brain. Therefore, in patients with stroke and TBI, the distribution of retinal fibers at the optic chiasm can be altered, resulting in changes in vision.

3 essential procedural components when assessing someone with dysarthria

A.

Consider the nature of stroke, determine what phonemes the person can't produce, perform further assessment
B.

Review medical history, identify salient features, identify confirmatory signs
C.

Review history, determine if the patient can be helped, do assessment

Correct Answer
B. Review medical history, identify salient features, identify confirmatory signs

Explanation
The correct answer is to review the medical history, identify salient features, and identify confirmatory signs. This is because when assessing someone with dysarthria, it is important to review their medical history to understand the underlying causes and any previous treatments. Identifying salient features helps to determine the specific characteristics of the dysarthria, such as the type and severity. Lastly, identifying confirmatory signs involves looking for additional physical signs or symptoms that support the diagnosis of dysarthria. These three components provide a comprehensive approach to assessing someone with dysarthria.

Palilalia refers to

A.

Monoloudness
B.

Slow AMRS
C.

Compulsive repetition of words

Correct Answer
C. Compulsive repetition of words

Explanation
Palilalia refers to the compulsive repetition of words. It is a speech disorder characterized by the involuntary repetition of words or phrases. People with palilalia often repeat their own words or the words of others immediately after they have been spoken. This repetition can occur multiple times, and it is often difficult for individuals with palilalia to control or stop the repetition. Palilalia can be a symptom of various neurological conditions, such as Tourette syndrome or certain types of dementia.
