A patient has recently sustained lower motor neuron damage to his/her trigeminal nerve (CN V) and is experiencing difficulty with mastication. Which of the following muscles could be experiencing deficits secondary to the nerve damage? - ANSWER Masseter Inspiration during quiet breathing involves contraction of the diaphragm that: - ANSWER Increases the volume of the thoracic cavity and causes pressure in the lungs to decrease. A person places a hand on a hot surface and experiences the sensation of heat. The feeling of heat is conveyed up to the primary somatosensory cortex in the parietal lobe. In order for this information to be received in this cortical area, it must first travel up the spinal column via the: - ANSWER Anterolateral system. When forming the vowel /u/ in boot which muscle most likely contracts? - ANSWER Orbicularis Oris There are several parts of a neuron that are important in the transmission of neural signals throughout the body. Which of the following components is MOST important for receiving signals from other neurons? - ANSWER Dendrite The spinal column is organized with respect to motor/sensory function, as well as upper and lower extremities. Cell bodies of lower motor neurons that control movement of the legs are generally found in: - ANSWER Ventral horn of the spinal column Dopamine is a neurotransmitter that plays an important role in neural signals involved in motor movement. Lack of dopamine in the substantia nigra has been associated with disease processes such as Parkinson's disease. What BEST describes the role of dopamine on the basal ganglia circuits? - ANSWER The net result of dopamine release to direct and indirect pathways of the basal ganglia facilitates movement. A person has a vital capacity of 5 liters and exchanges half a liter of air when typically breathing at rest (tidal volume). The person takes the biggest breath possible and inspires 3 liters of air. What is the expiratory reserve volume? - ANSWER 1.5 liters If a patient has denervation of the trigeminal nerve (CN V), which deficit would most likely result? - ANSWER Reduced capacity for mastication Cranial nerves can include motor functions, sensory functions, or a mix of both. Which of the following cranial nerves serve both motor and sensory functions? - ANSWER CN 5 (Trigeminal), 4 (Trochlear), 10 (Vagus) A patient who is experiencing non fluent aphasia most likely have some degree of cortical damage and Broca's area. This brain region is in which lobe? - ANSWER Frontal During the transmission of an action potential, after a neuron has fired there is an absolute refractory period. This is a delay during which a neuron is unable to transmit further action potentials. This delay must expire before that neuron can fire again because: - ANSWER Voltage-gated sodium channels are periodically inactivated after opening. A person experiences weakness on the right side of the face resulting in a right facial droop. Initial evaluation suggests cranial nerve damage. If verified, which cranial nerve is most likely damaged? - ANSWER Facial Contraction of the tensor veli palatini and levator veli palatini will not occur during the production of which of the following sounds? - ANSWER /m/ When producing the voiceless fricative /f/, the muscle that MOST LIKELY contracts is the: - ANSWER Posterior cricoarytenoid Neurotransmitters are chemicals in the brain that are important and sending neural signals between adjacent neurons. The best description of neurotransmitter release is that it: - ANSWER Excites or inhibits neighboring cells if it binds with a receptor and causes a channel opening.

The BEST measurement to make is the amount of movement in: - ANSWER F3 The frequency of a periodic sound is increased by 100 hertz. What effect would this change in frequency have on the wavelength of the sound? - ANSWER Decrease in the wavelength The pitch contour for a vowel shows several abrupt changes that the speech-language pathologist suspects may be inaccurate. The best way to objectively document accuracy or inaccuracy of the pitch contour is to: - ANSWER Look at the narrowband spectrogram to see if the harmonic contours show abrupt changes. The spectrum of a speaker's voice shows that H1 is 15 dB higher that H2 in amplitude. This MOST LIKELY indicates that the speaker has a: - ANSWER Breathy The pitch contour of a vowel shows that the pitch begins at 200 hertz (Hz). If the pitch contour is accurate, the period at the beginning of the vowel will be: - ANSWER .005 seconds T=1/f In order to accurately measure voice onset time (VOT) in a series of stop consonants, the speech-language pathologist should work from: - ANSWER Longer VOT What should the speech-language pathologist expect to observe if comparing amplitude spectra for a sinusoid and a periodic complex sound? - ANSWER The sinusoid has only one line, whereas the complex periodic sound has more than one line. The supralaryngeal vocal tract (SLVT) is a broadly tuned filter. This means that: - ANSWER inusoids will resonate if they are near a resonant frequency. If pitch contour for a vowel shows a frequency of 150 hertz (Hz) at the midpoint, the frequency of the fifth harmonic at the same location will be: - ANSWER 750 hz In examining a spectrogram of the phrase Say sheep produced by a male speaker, you notice that the lower limit of high-amplitude energy noise for both /s/ and / ʃ / is near 2500 hertz (Hz). This most likely indicates that: - ANSWER /s/ is being produced too far back in the mouth The center of gravity for a sibilant fricative is expected to be: - ANSWER off center in the spectrum In a narrowband spectrogram, the speech-language pathologist can see that the harmonic spacing becomes narrower throughout a vowel. When listening to the vowel, the SLP expects to hear that the vowel: - ANSWER Begins at a higher pitch and ends at a lower pitch. Two 150 hertz (Hz) sinusoids with a peak amplitude of 2 are added together. The sinusoids are 180 degrees out of phase. The resulting sound will be: - ANSWER 150 hz with a peak amplitude of 0.0 Tongue position is related to F1 frequency in that, when the tongue is: - ANSWER Low in the mouth, F1 is high Nasal consonants have a low-frequency nasal formant because the nasal cavity acts as: - ANSWER The largest resonating cavity, resulting in a low frequency F1. The speech-language pathologist is examining a spectrogram and a waveform for the initial sounds in a child's production of the word spaghetti. The waveform begins with a silence followed by a transient noise. In the spectrogram, the transient noise is followed by formants, then by high-amplitude, high frequency constant noise.
