Rated A+.
Three layers of the vocal folds - Answer - Epithelium (outer covering)
- Lamina propria (middle layer)
- Vocalis muscle (body)
Aryepiglottic folds vs. Ventricular folds - Answer Aryepiglottic = extends from the
arytenoids and separates the laryngeal vestibule from the pharynx
Ventricular = false vocal folds, can vibrate at low frequencies
Myoelastic-aerodynamic theory - Answer the vocal folds vibrate because of the forces
and pressure of air and the elasticity of the vocal folds.
Bernoulli effect - Answer The sucking motion of the vocal folds toward one another.
Primary cortical areas involved in speech-motor control - Answer Area 4: primary motor
cortex
Area 44: Broca's area
Areas 3, 1, 2,: somatosensory cortex
Area 6: supplementary motor cortex
Cranial nerve that innervates most of the pharynx - Answer Vagus nerve X
(And Spinal accessory nerve XI)
Four front teeth - Answer Incisors (in the premaxillary area)
Palatine process - Answer Bone that forms most of the hard palate
The back teeth - Answer Cuspid, bicuspid, and molar (in the alveolar process)

How do spinal nerves contribute to speech? - Answer They innervate respiratory
musculature (diaphragm & external and internal intercostals)
Autonomic nervous system regulates... - Answer the internal environment of our bodies
Two branches of the autonomic nervous system - Answer 1. Sympathetic (fight or flight)
Emotionally aroused states can affect communication
2. Parasympathetic (relaxation)
Parts of the peripheral nervous system (PNS) - Answer - Cranial nerves
, - Spinal nerves
