The neurons that transmit information away from the brain are called

• Afferent neurons

• Efferent neurons

• Primary neurons

• Peripheral neurons

An important structure adjacent to the brainstem that contains the hypothalamus (which controls the emotion) and the thalamus (which relays sensory impulses to various portions of the cerebral cortex) is called the

• Mesencephalon

• Diencephalon

• Superior cerebellar peduncle

• Postcentral gyrus

The corpus striatum is composed of three nuclear masses, which are the

• Globus pallidus, caudate nucleus, and putamen

• Putamen, caudate nucleus, and basal ganglia

• Supramarginal gyrus, angular gyrus, and putamen

• Substantia nigra, angular gyrus, and globus pallidus

The structure that regulates body posture, equilibrium, and coordinates fine motor movements is the

• Angular gyrus

• Corticospinal tract

• Circle of Willis

• Cerebellum

The anterior cerebral artery supplies blood to the

• Corpus callosum and basal ganglia

The laryngopharynx and the oropharynx add resonance to sounds produced by the larynx. The nasopharynx adds noticeable resonance to which sounds?

• K, g, t, d

• R, l, y

• F, sh, s

• M, n, ng

These are composed of a ring of connective tissue and muscle extending from the tips of the arytenoid cartilages to the epiglottis. They separate the laryngeal vestibule from the pharynx and help preserve the airway.

• True vocal folds

• Lamina propria

• Aryepiglottic folds
