Chapter 1: Anatomy, Neuroanatomy, and Physiology of the Speech Mechanism//Neuroanatomy and Neurophysiology: The Nervous System
Chapter 1
Respiration relies on the muscles of inspiration and expiration. The thick, dome-shaped muscle that separates the abdomen from the thorax is called the:
Diaphragm
Most pharyngeal muscles are innervated by cranial nerves:
X, XI
The neurons that transmit information away from the brain are called:
Efferent neurons
*An important structure adjacent to the brainstem that contains the hypothalamus (which controls emotions) and the thalamus (which relays sensory impulses to various portions of the cerebral cortex) is called the:
Diencephalon
The corpus striatum is composed of three nuclear masses, which are the:
Globus pallidus, caudate nucleus, and putamen
The structure that regulates body posture, equilibrium, and coordinated fine motor movements is the:
Cerebellum
*The anterior cerebral artery supplies blood to the:
Corpus collosum and basal ganglia
The laryngopharynx and the oropharynx add resonance to sounds produced by the larynx. The nasopharynx adds noticeable resonance to which sounds?
m, n, ng
These are composed of a ring of connective tissue and muscle extending from the tips of the arytenoid cartilages to the larynx. They separate the laryngeal vestibule from the pharynx and help preserve the airway.
Aryepiglottic folds
The cranial nerve that innervates the larynx and also innervates the levator veli palatini, palatoglossus, and palatopharyngeus muscles is:
CN X, the vagus nerve
(with XI)
Note: tensor veli palatini (V)
*Muscles that contribute to velopharyngeal closure through tensing or elevating the velum are the:
Palatoglossus, tensor veli palatini, and levator veli palatini
LVP is primary elevator of velum; TVP tenses velum; Palatoglossus evelates and depresses velum; Palatopharyngeus narrows pharyngeal cavity, lowers velum, may assist in elevating larynx
The structure at the inferior portion of the tongue that connects the tongue with the mandible is called the:
Lingual frenum
*When a person is producing voiced and voiceless /th/, the muscle that is most involved is the:
Genioglossus
Protrusion=genioglossus; Retrusion=hyoglossus, styloglossus, genioglossus; Depression=genioglossus, hyoglossus; Elevation=styloglossus; Shortening=longitudinal intrinsic fibers; Narrowing=transverse intrinsic fibers; Flattening=vertical intrinsic fibers
Note: Extrinsics= genioglossus, styloglossus, hyoglossus, palatoglossus; Intrinsics= superior and inferior longitudinal, transverse, vertical
*Which muscles from the list below are the most involved in adducting the vocal folds?
Lateral cricoarytenoid and transverse arytenoid
TA vibrates and produces sound; oblique arytenoid pulls apex of arytenoid medially; CT lengthens and tenses VFs; PCA abducts VFs
The cerebral hemispheres are connected by:
Commissural fibers
The central nervous system’s primary mechanism of attention, alertness, and consciousness, which is also related to sleep-wake cycles, is the:
Reticular activating system
The primary motor cortex in the frontal lobe is located on the:
Precentral gyrus
Which of the following is FALSE?
A. Wernicke’s area in the temporal lobe is critical to the comprehension of spoken language
B. Wernicke’s area is connected to Broca’s area in the frontal lobe through the arcuate fasciculus
C. The occipital lobe contains the primary visual cortex
D. The angular gyrus in the occipital lobe is important for interpretation of somesthetic sensations such as pain, touch, and temperature
E. The pyramidal system consists of the corticospinal and corticobulbar tracts
Answer: D
The angular gyrus is in the parietal lobe
Which of the following is TRUE?
A. The cerebral ventricles are interconnected cavities filled with fluid produced by the dura mater
B. The meninges of the brain consist of the dura mater, pia mater, and arachnoid
C. The basilar artery eventually divides into four posterior cerebral arteries
D. The external carotid artery is the major supplier of blood to the brain
E. The circle of Willis prevents a common blood supply to various cerebral branches
Answer: B
Cerebral ventricles are interconnected cavities filled with CSF produced by the choroid plexus; Basilar artery divides into two posterior cerebral arteries; The internal carotid artery is the major supplier of blood to the brain; Circle of Willis provides a common blood supply to various cerebral branches
Chapter 2: Physiological and Acoustic Phonetics: A Speech Science Foundation
Chapter 2
The term coarticulation refers to:
The influence of one phoneme upon another in production and perception wherein two different articulators move simultaneously to produce two different speech sounds
Broad phonemic transcription involves:
The use of IPA symbols to transcribe phonemes by enclosing them within slash marks (e.g., /f/)
The two properties of a medium that affect sound transmission are:
Mass and elasticity
