Clinical Neuroscience Quiz 3 Review - Weeks 10-12 #2

Which of the following is a primary function of the cerebellum?

The cerebellum is attached to the pons via the:

Information from proprioceptors in the limbs reaches the cerebellum primarily via which of the following tracts?

Which of the following is the sole efferent output neuron of the cerebellar cortex?

Planning, initiating, controlling, and correcting voluntary movements are primarily the responsibility of which deep cerebellar nucleus?

The vestibulocerebellum (flocculonodular lobe) primarily receives input from:

Damage to the vestibulocerebellum is most likely to result in which of the following signs?

Goal-directed movements of the limbs are primarily coordinated by the:

Challenges with rapid alternating movements (dysdiadochokinesia) are most commonly associated with damage to the:

The cerebellum contributes to the timing of movements. Lesions in the cerebellum often result in deficits in timing and what other characteristic of movement execution?

The primary role of the vestibular system is to detect:

Angular acceleration of the head is detected by the:

Linear acceleration and head tilt are primarily detected by the:

The sensory receptors within the semicircular canals are hair cells located in the:

The gelatinous structure that embeds the hair cells within the ampullae is called the:

In the push-pull relationship of the vestibular system, a head rotation to the left typically causes:

The vestibulo-ocular reflex (VOR) ensures that when the head turns to the right, the eyes will:

Benign Paroxysmal Positional Vertigo (BPPV) is characterized by otoconia becoming displaced into the:

The primary auditory cortex is located in which lobe of the brain?

The organ responsible for transducing sound waves into neural signals is the:

Photoreceptor cells responsible for color vision and high visual acuity are called:

Photoreceptor cells that are highly sensitive to light and responsible for vision in low-light conditions are called:

The axons of which cells form the optic nerve?

At the optic chiasm, fibers from the nasal retina of each eye:

The primary visual cortex is located in which lobe of the brain?

A lesion of the left optic nerve anterior to the optic chiasm would result in:

A lesion at the optic chiasm that selectively damages the crossing fibers would result in:

A lesion of the right optic tract posterior to the optic chiasm would result in:

The dorsal processing stream of visual information is primarily involved in:

Unilateral spatial neglect is most commonly associated with damage to the:

The fovea is the region of the retina with the highest visual acuity due to its high concentration of:

The "blind spot" in the visual field is due to the absence of photoreceptors at the:

The ciliary muscle controls the shape of the:

The iris regulates the amount of light entering the eye by controlling the size of the:

In the visual pathway, the first synapse occurs in the:

The optic radiations project to the primary visual cortex through which cerebral lobe?

Difficulty recognizing faces (prosopagnosia) can result from damage to which visual processing stream?

The primary role of the cornea is to:

Visual motion sensitivity or motion sickness is thought to be due to a conflict between sensory input from the:

A patient presents with loss of vision in the temporal field of the left eye and the nasal field of the right eye. Where is the most likely location of the lesion?

A patient recovering from a cerebellar stroke exhibits intention tremors, particularly when reaching for objects. This symptom primarily reflects impaired function of which cerebellar region and deep nuclei?

During a neurological exam, a patient is asked to rapidly alternate between pronation and supination of their hand. The patient performs the movements slowly and clumsily. This finding suggests impairment within which neural structure?

A person is spun around in a chair. Which of the following describes the activity of the semicircular canals and the resulting vestibulo-ocular reflex (VOR) that allows them to maintain focus on a fixed point?

A patient reports difficulty seeing objects clearly in their peripheral vision, particularly in low light conditions, but they can see fine details when looking directly at an object in bright light. Which of the following best explains this patient's vision problems?

A patient suffers a stroke that damages the optic tract on the left side. Which specific visual field deficit is most likely to result from this lesion?
