study of the structures of the body Anatomy
branch of Biology that is concerned with the process and function of parts of the body Physiology
provides the driving force for speech by generating positive air pressure values beneath the vocal folds Respiratory system
vibrate at high rates of speed, setting air molecules in the vocal tract into multiple frequencies of vibration laryngeal system
acts as an acoustic filter allowing certain frequencies to pass into the atmosphere while simultaneously blocking other frequencies Articulatory/Resonating system
pair of air-filled elastic sacs that change in size and shape and allow us to breathe Lungs
cartilaginous membranes tube by which air moves to and from the lungs Trachea
Broad sheet of connective tissue covering the front of the abdominal wall Abdominal Aponeurosis
breathing to sustain life Resting tidal breathing
the pressure inside the lungs Alveolar pressure
the superior termination of the trachea that protects the lower airways and is the primary sound source for speech production Larynx
small, pendulous structure suspended from the soft palate Uvula
contact of the velum with the lateral and posterior pharyngeal walls, thus separating the oral and nasal cavities Velopharyngeal Closure
production of sound by vocal fold vibration Phonation
The lowest frequency component of a complex vibration Fundamental Frequency
frequencies in a complex sound that are integer multiples of the fundamental frequency Harmonics
the basic unit of the central nervous system consisting of the cell body, axon, and dendrites Neuron
the minuscule space between the axon of one neuron and the dendrites of the next, where communication between neurons occurs Synapse
comprises the brain and spinal cord Central Nervous System
a 2 cm wide gyrus immediately in front of the central sulcus of the brain that controls voluntary movements Primary Motor Cortex
paired egg-shaped structures in the brain that serve as relay station for incoming and outgoing information. Thalamus
large subcortical nuclei that regulate motor functioning and maintain posture and muscle tone Basal Ganglia
comprises the midbrain, pons, and medulla. Important for regulating respiration, chewing, swallowing, and automatic functions of the body Brainstem
a lower brain structure consisting of two hemispheres that smoothly regulates and coordinates the control of purposeful Cerebellum
