Vocal Fold Microstructure
The Vocal Fold Life Cycle
100

The muscles of respiration are divided into these two categories.

Inspiration and expiration

100

These are the 3 largest cartilages of the larynx.

Epiglottis, thyroid, cricoid
100

These are the 3 subsystems of voice production

Respiration, phonation, and resonance

100

This is the most superficial layer of the vocal folds.

Epithelium

100
Where the larynx is situated in newborns.

High in the neck

200

When this muscle contracts, it depresses the abdomen and increases the vertical dimensions of the lungs and thoracic cavity.

The diaphragm

200

This cartilage sits above the first tracheal ring.

Cricoid

200

These are 3 basic functions of the larynx.

airway ventilation, airway protection, and phonation for speech

200

Two environmental factors that may affect the epithelium

humidity, dehydration, pollution, reflux

200

What we call geriatric changes in voice quality and laryngeal appearance.

Presbylaryngeus

300

This is an upward fanlike muscle that is active during speech breathing; When it contracts it lowers the rib cage.


Internal Obliques

300

This cartilage creates the anterior border of the airway column.

Thyroid

300

This forms the upper rim of the larynx.

Aryepiglottic folds

300

This layer of the vocal folds is divided into superficial, intermediate, and deep layers.

Lamina Propria

300
Elderly patients often present with this shape of vocal folds.

thinned/bowed

400

This muscle is the sole abductor of the vocal folds.

Posterior cricoarytenoid

400

When the tips of the vocal processes are pointed laterally, the vocal folds are ____.

Abducted

400

Do not compress this when performing manual palpation

Carotid artery

400

This is the only tissue of the vocal folds that is both active and passive.

Vocalis Muscle

400

By puberty, the larynx has typically descended to this cervical vertebrae

C6-C7

500
The intrinsic laryngeal muscles affect these 3 aspects of the vocal folds.

position, length, & tension

500

These are the 3 paired cartilages of the larynx.

arytenoid, corniculate, cuneiform

500

These are some functions of the false vocal folds

Tight compression during rapid thoracic muscle contraction (coughing, sneezing).

Building up subglottal pressure for longer duration while lifting, emesis, childbirth, defecation.

 
500

This nerve innervates the vocalis muscle

Recurrent laryngeal nerve of the Vagus Nerve (CNX)
500

This is to be expected for a few days after extubation.
