Respiratory
This dome-shaped muscle contracts and moves downward to help air enter the lungs during inhalation.
What is a Diaphragm?
Name the three types of muscle tissue.
What are smooth, cardiac, and skeletal?
This muscle contraction produces force without changing muscle length.
What is an isometric contraction?
Name the four processes that are needed to produce speech.
What is respiration, phonation, resonance, and articulation?
This occurs when the vocal folds close during a normal swallow.
What is breathing stops?
This pressure is known as one of the most important aspects of speech production, and it is made up of all of the pressures within the lungs.
What is alveolar pressure?
This nerve is what activates the muscles and causes the muscle fibers to contract.
What is a peripheral nerve?
These are the four major abdominal muscles needed for active expiration.
What are the rectus abdominis, external oblique, internal oblique, and transversus abdominis?
Air pressure that collects under the vocal folds and controls the loudness and phonation of speech.
What is subglottal pressure?
This flap-like structure closes over the airway during swallowing to help keep food out of the lungs.
What is the epiglottis?
Airway branches that are made of smooth muscle and mucous membrane that lead to the respiratory bronchioles, then to the alveolar ducts to end in alveolar sacs.
What are bronchioles?
These tough bands of connective tissue attach muscles to bones and help transmit the force needed for movement.
What are Tendons?
This muscle is always used during resting tidal breathing, even in the supine position.
What is the diaphragm?
Name the five subsystems responsible for speech production.
What are the Velopharyngeal-nasal, Pharyngeal-oral, Laryngeal, Respiratory, and Nervous subsystems?
This is the stage where a fetus develops the ability to swallow.
What is the early to mid fetal period?
States that pressure and volume are inversely proportional for as the lung volume increases alveolar pressure decreases and vise versa it will let air into the lungs.
What is Boyle’s Law?
The 11 muscles that are between the ribs that move downward and forward to raise the rib cage during inspiration, increasing the volume of the thoracic cavity.
What are external intercostals?
This is the action that the larynx completes during a swallow.
What is elevates?
This type of breathing requires a quick inhalation followed by a long exhalation to support speech.
What is speech breathing?
This phase of swallowing begins when the bolus moves from the mouth into the pharynx.
What is the pharyngeal phase?
The maximum amount of air an individual can exhale after maximum inhalation (TV + IRV+ ERV).
What is vital capacity?
This bodily structure consists of the rib cage, diaphragm, abdominal wall, and muscles that support the airflow needed for speech.
What is the chest wall?
The prime mover muscle responsible for producing a specific movement is called this.
What is an agonist?
This process changes airflow from the lungs into sound through vibration of the vocal folds.
What is phonation?
This reflexively triggered phase of swallowing moves the bolus through the esophagus toward the stomach using peristaltic contractions.
What is the esophageal phase?
