Skeletal Framework Basics
This is one main job of the skeletal framework in breathing.
What is providing structure and protection for the lungs?
This system includes all structures involved in breathing.
What is the respiratory system?
This is the primary muscle used for normal inhalation.
What is the diaphragm?
These membranes and fluid connect the lungs to the chest wall.
What are the pleural membranes and pleural fluid?
This term describes controlled slowing of airflow at high lung volumes during speech.
What is inspiratory checking?
This function allows the lungs to expand and shrink during breathing.
What is allowing movement for breathing?
These are the upper airway structures air passes through first.
What are the nose, nasal cavity, pharynx, and larynx?
When the diaphragm contracts, it moves in this direction.
What is downward?
This term describes how the lungs and chest wall move together.
What is mechanical coupling?
Inspiratory checking occurs near this point in speech breathing.
What is the beginning of an extended utterance?
These are used as anchor points for muscles involved in breathing.
What are attachment points for respiratory muscles?
This tube carries air from the larynx to the lungs.
What is the trachea?
This change in the chest cavity allows air to flow into the lungs.
What is increased thoracic volume and decreased pressure?
At rest, the lungs naturally want to move in this direction.
What is inward recoil?
This body position commonly uses inspiratory checking during speech.
What is upright posture?
This helps keep the lungs at an appropriate resting size.
What is maintaining resting lung volume?
These structures make up the pulmonary apparatus.
What are the lungs, pleura, and bronchial tree?
These muscles help expand the rib cage during inspiration.
What are the external intercostals, parasternal intercostals, scalenes, and sternocleidomastoid?
At rest, the chest wall naturally wants to move in this direction.
What is outward recoil?
This muscle group is primarily responsible for inspiratory checking.
What are the inspiratory muscles (especially the diaphragm and external intercostals)?
These are the two main divisions of the skeletal framework.
What are the pulmonary apparatus and the chest wall?
These muscles and structures make up the chest wall.
What are the rib cage, diaphragm, intercostal muscles, and abdominal wall muscles?
These muscles are mainly active during forced expiration.
What are the internal and innermost intercostals?
The balance of these opposing forces creates this breathing state.
What is a stable resting position for breathing?
Inspiratory checking helps prevent this during speech.
What is rapid passive air release?
