Anatomy of Respiration
These muscles provide the active forces of inhalation.
What are the diaphragm and the external intercostals
This cartilage appears to look like a signet ring and sits at the superior portion of the trachea.
What is the cricoid cartilage?
These muscles are the extrinsic laryngeal muscles located above the hyoid bone (suprahyoid).
What are the digastric, stylohyoid, mylohyoid, and geniohyoid muscles?
The thyromuscularis and thyrovocalis are bundles of muscle fibers of this muscle.
What is the thyroartenoid?
These are the folds of the larynx.
What are the aryepiglottic folds, false vocal folds, and true vocal folds?
The thorax expands / contracts, the lungs also expands / contracts due to this.
What is Pleural linkage
This cartilage houses the vocal folds
What is the thyroid cartilage?
These are the infrahyoid muscles of the larynx.
What are the sternohyoid, omohyoid, sternothyroid, and thyrohyoid muscles?
This bundle of muscles of the thyroartenoid is a VF tenser and is the main source of vibration.
What is the Thyrovocalis?
This bundle of connected tissue and muscle open during phonation and respiration, close during swallowing.
What are the aryepiglottic folds?
The lungs and thorax return to the resting state after being stretched due to this.
What is elastic recoil?
This portion of the arytenoid cartilage attaches to muscles that open and close the vocal folds
What is the muscular process/lateral projection?
This group of muscles all depress the hyoid bone
What are the infrahyoid muscles?
Contraction of this bundle of muscles pulls arytenoids anteriorly, causing the vocal folds to “bunch up” increasing mass of the vocal folds controlling pitch.
What is the Thyromuscularis?
These folds contain numerous mucous glands that help lubricate and keep the supraglottis open for phonation and respiration.
What are the false vocal folds?
These muscles are involved in the active forces of exhalation?
What are the abdominal muscles and internal intercostals?
These two small, pyramid-shaped cartilages that sit on posterior segment of cricoid cartilage via cricoarytenoid joint.
What are the arytenoid cartilages?
These muscles pull the hyoid bone up and back
What are the posterior belly of the digastric muscle and the stylohyoid muscles?
Contraction of this muscle causes the vocal folds to come together.
What are the Interarytenoids?
These folds abduct to open the glottis for respiration and to produce voiceless sounds and adduct to close the glottis for swallowing and to produce voiced sounds.
What are the true vocal folds?
Adequate control of lung volume and respiratory muscle activity during expiration is crucial for the regulation of this.
What is subglottic pressure?
The 3 paired cartilages of the larynx.
What are the cuneiform, corniculate, and arytenoid cartilages?
This muscle aids to reopening the laryngeal inlet by depressing the hyoid bone and larynx, thus reinstating the breathing process.
What is the sternohyoid muscle?
This is the only intrinsic laryngeal muscle that abducts or opens the vocal folds.
What is the posterior cricoarytenoid?
This is the muscle layer of the true vocal folds.
What is the Thyroarytenoid muscle?
