  • Larynx extent: inlet of larynx to the cricoid cartilage
  • Relation: 
  1. ANTERIOR: epiglottis

  • Vestibular fold and vocal fold is dividing the cavity of larynx into three :
  1. Region above vestibular fold: vestibule, supraglottis.
  2. Region between vestibular fold and vocal fold: ventricle
  3. Region below vocal fold: infraglotis
  • Sinus of morgagni lies between vestibular and vocal fold.
  • Sinus of morgagni /ventricle of larynx extend anteriorly till the lamina of thyroid ,cartilage is known as saccule of larynx 
  • Saccule of larynx: oil can of  larynx provide lubrication to voice as cavity lacks mucous membrane.

General talk:

Dentistry is not only learning about tooth decay,endodontics,yes i agree our primary focus is oral cavity but we do learn human anatomy especially head and neck anatomy as part of our first year.if you have been searching in google keep notes for a note website which has handwritten notes,good notes,you have landed in the right page . Do let us in the comment section if this post helped you with your preparation and please feel free to mail us at stencildent@gmail.com for product endorsement and feedback regarding our post .
