Most pharyngeal muscles are innervated by cranial nerves:
X, XI
XI, XII
IX, X
VIII, X
The neurons that transmit information away from the brain are called:
afferent neurons
primary neurons
peripheral neurons
efferent neurons
Important structure adjacent to the brainstem, contains hypothalamus/thalamus:
mesencephalon
superior cerebral peduncle
diencephalon
postcentral gyrus
The corpus striatum is composed of which three masses:
mesencephalon, RAS, caudate nucleus
globus pallidus, caudate nucleus, putamen
supramarginal gyrus, angular gyrus, globus pallidus
putamen, caudate nucleus, basal ganglia
The ACA supplies blood to the:
corpus callosum and basal ganglia
caudate nucleus and globus pallidus
substantia negra
corpus striatum
I extend from the tips of the arytenoid cartilages to the larynx, separate the laryngeal vestibule from the pharynx, and preserve the airway. Who am I?
Aryepiglottic folds
Ventricular folds
Lamina propina
True vocal folds
I'm the cranial nerve that innervates the larynx and also the levator veli palatini, palatoglossus, and palatopharyngeus muscles. Who am I?
XI: Spinal Accessory
X: Vagus
XII: Hypoglossal
V: Trigeminal
When a person is producing voiced and voiceless /th/, the muscle that is most involved is:
palatopharyngeus
buccinator
genioglossus
styloglossus
The 11 paired EXTERNAL intercostals ______:
pull ribs downward
raise ribs up and out
The 11 paired INTERNAL intercostals ______:
raise ribs up and out
pull ribs downward
Which is NOT a biological function of the larynx?
closure of the trachea to protect lungs
production of cough to clear airway
closure of VFs to build subglottic pressure
phonation for speech
Which of the following is NOT a layer of the vocal folds?
epithelium

Which of the following is NOT a primary cortical area involved in speech-motor control?
area 4 (primary motor cortex)
area 44 (Broca's)
area 6 (supplementary motor cortex)
area 22 (Wernicke's)
I provide all sensory information to the larynx and motor innervation solely to the cricothyroid muscle. Who am I?
Recurrent laryngeal nerve
Superior laryngeal nerve
I supply all sensory information below the vocal folds. Who am I?
Recurrent laryngeal nerve
Superior laryngeal nerve
Which is NOT a segment of the pharyngeal cavity?
mesopharynx
nasopharynx
laryngopharynx
oropharynx
