Test Bank - Chapter 05: Auditory and Sensory Pathways

The __________ acts as a transducer, changing physical stimuli into neural impulses.

cochlea

The organ of Corti is located in

the scala media.

Outer hair cells

None of the above describe outer hair cells.

Efferent innervation to the organ of Corti likely serves to

inhibit the excitation of the spiral ganglion cells.

Which of these processes does not directly involve the auditory cortex?

Analysis of frequency and discrimination of intensity

Tonotopic organization is found in

all of the above

Which of the following is NOT a characteristic of auditory agnosia?

The lesion resulting in auditory agnosia is unilateral.

Which of the following sensory receptors are responsible for detecting muscle movement?

Proprioceptors

Cutaneous sensation would be categorized as a _________ sense in the neurophysiologist's classification scheme.

general

The unimodal cortex includes all of the following areas EXCEPT

association cortex

Which of the following could be said to be true of agnosia?

It can occur in one sensory modality.

The inability to determine the location of a tactile stimulation is called

atopognosis

Which of the following structures would contain a second-order neuron in the somatic sensory pathway?

The lemniscus.

The _________-order neuron of the somatic sensory pathway crosses over to the contralateral side.

second

The unconscious sense of where one body part is in relation to the other in automatic movement sequences is processed in the

the spinocerebellar tract

Sensations of pain and temperature are processed in

lateral spinothalamic tract and anterolateral tract

A student reaches into a full backpack and is able to retrieve a pencil without looking. This is an example of

form perception

A child who recoils at the touch of a feather may be demonstrating

hyperesthesia

Which of the following is not true of the type of oral sensory receptors called mechanicoreceptors?

They respond to both taste and touch in the oral cavity

The first-order neurons in the eyes are called

photoreceptors and bipolar cells

An image of an object in the left half of the visual field

will be picked up by photoreceptors in both eyes

Stereoscopic three-dimensional vision is facilitated through the

ipsilateral passage of temporal fibers from each eye to the optic tract and decussation of the nasal fibers from each eye to the optic tract

In order for __________________ to be stimulated in the visual cortex, an object must be of a particular length

hypercomplex fields

Although visual processing requires the interconnectivity of all the pathways and cortical areas, the _______________________ has been shown to play a role in recognizing familiar faces.

temporal visual cortex

Lesions in the __________________________ may result in visual agnosia.

what or ventral stream pathway

Which of the following nuclei is/are not a way station of the auditory pathway? (Select all that apply.)

Nucleus gracillus and Nucleus cuneatus

The fasciculus cuneatus carries information pertaining to light touch from the legs and lower body.

FALSE

A patient with a lesion in the right lateral spinothalamic tract would not be able to feel pain on the left side of the body.

TRUE

A patient has a positive Romberg sign, which means his body sways abnormally with feet together, eyes closed. When the patient opens his eyes, he stops swaying. This means the lesion is in the cerebellum.

FALSE

The auditory brainstem response tests the integrity of the auditory cortex

FALSE

A person diagnosed with auditory agnosia demonstrated difficulty interpreting stimuli because of a hearing impairment

FALSE

Pure word deafness impairs the ability to understand written stimuli

FALSE

Like auditory agnosia, a visual agnosia presents as difficulty interpreting visual stimuli in the presence of intact vision, whether corrected or not

TRUE
