Cranial Nerves & Their Functions | Baamboozle - Baamboozle

The Pyramidal (direct) motor pathway is responsible for:

Voluntary, precise motor control of speech muscles

Reflexive motor patterns

Balance and posture

Emotional prosody

The Corticobulbar tract carries motor commands:

From the cortex to cranial nerve nuclei in the brainstem

From brainstem to spinal cord

From cochlea to brainstem

From cerebellum to pons

The Pons contains nuclei for which cranial nerves?

V, VI, VII, VIII

IX, X, XI

I, II, III

IV, V, VI

The Medulla oblongata houses nuclei for:

Cranial nerves IX, X, XI, XII

Cranial nerves I–IV

Cranial nerves V–VIII

Visual pathways only

The Internal capsule carries:

Motor and sensory tracts between cortex and brainstem

Auditory fibers from cochlea

Cranial nerve nuclei

Reflex centers

The Thalamus functions primarily as:

A relay station for sensory information to the cortex

The center of memory storage

The generator of vocal fold vibration

The initiator of motor programs

Cerebellar damage often results in:

Ataxic dysarthria

Aphasia

Spastic dysarthria

Flaccid paralysis

The Cerebellum is critical for:

Balance and motor coordination

Visual scanning

Emotional control

Speech comprehension

Lesions to the Basal ganglia may cause:

Hyperkinetic or hypokinetic dysarthria

Ataxic dysarthria

Flaccid dysarthria

Apraxia of speech

The Basal ganglia regulate:

Fine motor coordination and tone

Language comprehension

Hearing sensitivity

Visual tracking

The right hemisphere is most involved in:

Pragmatics, prosody, and holistic processing

Syntax and morphology

Phoneme discrimination

Word retrieval

Damage to the left inferior frontal lobe usually results in:

Broca’s aphasia

Wernicke’s aphasia

Global aphasia

Conduction aphasia

The Supramarginal gyrus is associated with:

Phonological processing and repetition

Limb movement

Visual perception

Emotional regulation

Heschl’s gyrus corresponds to the:

Primary auditory cortex

Motor strip

Visual association area

Corpus callosum

The Angular gyrus plays a key role in:

Reading and writing

Motor speech

Tongue coordination

Auditory discrimination

Damage to the Arcuate fasciculus typically causes:

Conduction aphasia

Anomic aphasia

Global aphasia

Transcortical motor aphasia

The Arcuate fasciculus connects:

Broca’s and Wernicke’s areas

Frontal and occipital lobes

Motor and sensory cortices

Cerebellum and brainstem

Wernicke’s area is primarily responsible for:

Auditory comprehension of language

Motor planning for speech

Visual word recognition

Motor execution

Lesion to Broca’s area results in:

Nonfluent, effortful speech with relatively good comprehensi

Fluent speech with paraphasias

Global aphasia

Pure word deafness

Broca’s area is located in:

Inferior frontal gyrus, typically left hemisphere

Superior temporal gyrus

Angular gyrus

Parietal lobe

The Accessory nerve (XI) contributes to:

Head and shoulder movement via trapezius and SCM

Palatal retraction

Taste perception

Laryngeal closure

Damage to cranial nerve XII results in tongue deviation:

Toward the weaker side

Away from the lesion

Straight forward

No deviation

The Recurrent laryngeal branch of the Vagus nerve innervates:

All intrinsic laryngeal muscles except the cricothyroid

Cricothyroid only

Pharyngeal constrictors

Facial muscles

A lesion to cranial nerve VIII (Vestibulocochlear) may cause:

Hearing loss and balance difficulties

Dysarthria

Hypernasal speech

Tongue deviation

Damage to the Facial nerve (VII) often results in:

Facial asymmetry and poor labial closure

Hypernasality

Impaired tongue protrusion

Reduced jaw strength

Cranial nerve X (Vagus) innervates muscles for:

Laryngeal movement and velar closure

Chewing

Tongue retraction

Lip protrusion

Cranial nerve IX (Glossopharyngeal) mediates:

Taste posterior ⅓ of tongue and pharyngeal elevation

Tongue tip movement

Lip rounding

Jaw closing

The Facial nerve (VII) controls:

Facial expression and taste to anterior ⅔ of tongue

Vocal fold adduction

Tongue protrusion

Soft palate elevation

The cranial nerve primarily responsible for jaw movement is:

V (Trigeminal)

X (Vagus)

XII (Hypoglossal)

VII (Facial)
