Volumes and Capacities vs Pressures
Volumes and Capacities relate to quantities
Pressure = force and area
Measures volumes and capacities to establish norms
Measures pressure (certain amount of pressure needed to produce speech)

Capacities (4)
Vital Capacity
Inspiratory Capacity

Total Lunch Capacity
Vital Capacity
total amount of air that can be inspirated after a maximum exhalation

Amount of air left in lungs after tidal expriation
Inspiratory Capacity
Amount of air that can be inhaled after tidal expiration
Total lung capacity
All of it, including residual volume
Volumes (4)
Inspiratory Reserve Volume
Tidal Volume
Expiratory Reserve Volume
Residual Volume
Inspiratory Reserve Volume
Volume of air that can be inhaled after a tidal inspiration
Expiratory Reserve Volume
Volume of air that can be exhaled after a tidal expiration
Residual Volume
air remaining in lungs after a forced expiration (can't be exhaled)
Dead Air Space
air within vocal tract that is NOT used for gas exchange
Framework of Larynx
3 unpaired & 3 paired cartilages
lined with mucous membrane
sits on top of trachea
Cartilages of larynx (6)
Cricoid Cartilage (definition of structure)
smaller in front like a signet ring
most inferior, only one
looks like a fancy tracheal ring
Crocoid structures (anterior, lateral, posterior)
Anterior is smaller, to allow for vocal folds to attach
Lateral side has articular facets where thyroid cartilage attaches
Posterior side has other cartilages called arytenoids
Thyroid cartilage definition
Vocal fold attaches here
Unpaired cartilage
Largest of laryngeal cartilages
Thyroid cartilage structures
2 laminae (flat parts at the sides)
Thyroid angle = where laminae come together in front
Thyroid notch = highest point of the angle
Inferior horns (cornus) = attach at bottom
Superior horns = attach to hyoid bone
Arytenoid cartilage definition
Paired cartilage
Sit on top of posterior cricoid
Arytenoid Cartilage structures
Vocal Process (2) = more on anterior side where vocal folds attach and also on thyroid cartilage in front below notch
Muscular process (2) = on lateral side, where other muscles attach
Corniculate cartilage
on top of artytenoid cartilage
point of articulation with the arytenoid cartilages
Epiglottis cartilage
Attaches to the thyroid cartilage anteriorally and inferiorally
Sits right in middle between thyroid and hyoid bone
Epiglottis Structures (5)
Thyroepiglottic ligament = attaches to thyroid cartilage
Glossoepiglottic ligament = tongue to epiglottis (attached superiorally)
Aryepiglottic folds = connects side of arytenoid to epiglottis
Pyraform sinuses = spaces betweeen aryepiglottic folds and thyroid cartilage (lateral)
Valleculae sinuses = space between base of tongue and epiglottic (food gets stuck here)
Cuneiform Cartilage
Embedded w/aryepiglottic folds
provide support for aryepiglottic folds
Hyoid bone
Union between tongue and larynx

Only bone in body not connected to another bone
Large anterior called Corpus
Point of attachment for 6 muscles
Movement of cartilages
Cricothryoid joint
Cricoarytenoid joint
Cricothyroid joint
Between Cricoid & thyroid cartilages
In front, when it contracts, pulls them closer together
Stretches vocal folds which raises pitch of voice
Responsible for changes in vocal fold frequency
Cricoarytenoid joint
Between cricoid and arytenoid
Arytenoids make all sorts of movements
Responsible for vocal fold movement
Inner Larynx
Vocal folds = bands of tissue, majority consist of muscle
Membranes & Ligaments help to connect structures
Extrinsic Membranes & Ligaments (7)
Thyrohyoid membrane = between thyroid cart and hyoid bone
Lateral thyrohoid ligament = small connection between superior horn and hyoid bone
Medial Thyrohyoid ligament = connects thyoid cartilage notch to hyoid bone
Hyoepiglottic & Thyroepiglottic ligaments = connection b/w epiglottis and hyoid bone

= travels from true vocal folds to top part of larynx
= includes aryepiglottic folds and false vocal folds
Cornus Elasticus = lines larynx from true vocal folds down (inferior to vocal folds)
Vocal Folds - 5 layers
Superficial = outermost, think, epithelial
3 Lamina Propia
= superficial, intermediate, deep
= superficial (very thin)
= all are very elastic
= deep layer is thicker and not as flexible
Thyrovocalis muscle = bulk of vocal folds
Alternate names of vocal folds
Mucosal lining = combination of 2 superficial layers
