Larynx in anterior and posterior views→ for airway protection, protects things from coming in/out
- Epiglottis
- Hyoid bone
- Thyrohyoid membrane
- Superior horn of thyroid cartilage
- Superior horn of thyroid cartilage
- Thyroid cartilage lamina
- Thyroid notch
- Inferior horn of thyroid cartilage
- Cricothyroid ligament
- Cricoid cartilage
- Trachea
**Aids in sound source
**The posterior is open because it is connected to the pharynx
**esophagus is posterior to the larynx and trachea
Cartilage of Larynx (some paired, some not paired):
- Epiglottis (unpaired)
- Cuneiform cartilage (paired) → for structural purposes
- Thyroid cartilage (unpaired)
- Corniculate cartilage (paired) → at the superior aspect of the arytenoid
- Arytenoid cartilage (paired)
- Cricoid cartilage (unpaired)
Recurrent laryngeal nerve→ aids in coughing
Superior Laryngeal nerve→ aids in choking/regurgitation
Coronal cut of the Larynx
- Larynx is innervated bilaterally
- Vocal folds/vocal cords→ interchangeable (narrowing of the airway at vocal folds)
- This area is called the glottis where the true vocal folds are
- Supraglottic is above
- True vocal folds
- False vocal folds
Make-up of the vocal folds
- Thyroarytenoid muscle, thyromuscularis part
- Thyroarytenoid muscle, thyrovocalis part
- Squamous epithelium→ made of squamous skin cells
- Superficial lamina propria→ damage to this can change the quality of the voice**
- Intermediate lamina propria
- Deep lamina propria
- Vocal ligament→ tougher/stiffer than muscle, embedded in lamina propria

***The Lamina Propria float on top of one another
Vocal Folds seen from above:
- Root of tongue
- Epiglottis
- Vallecula
- Aryepiglottic fold
- Ventricular fold
- Trachea
- Cuneiform tubercle
- Vocal fold
- Piriform sinus
- Arytenoid→ attach to focal folds
Cartilage of the Larynx
- Cricoid Cartilage
- Arch is anterior
- Facet for arytenoid
- Lamina
- Facet for thyroid
- Thyroid cartilage
- Laryngeal prominence→ adam’s apple
- Thyroid notch→ behind the notch is where the epiglottis attaches
- Triticeal cartilage (not important)
- Superior cornu (attach to hyoid bone)
- Lamina angle
- Inferior cornu (attach to cricoid)
- Oblique line
- Arytenoid Cartilage
- Corniculate cartilage
- Apex
- Muscular processs
- Vocal process
- Cricoid
- Cricoid cartilage
Hyoid Bone:
- Genioglossus muscle
- Stylohyoid muscle
- Omohyoid muscle
- Sternohyoid muscle
- Mylohyoid muscle
- Hyoglossus muscle
- Middle constrictor muscle
