LARK

• Larynx


  Organ for production of voice or phonation.

  
  

  Air passage and acts as a sphincter at the inlet of lower respiratory passages
• Nose

  
  

  Nasopharynx

  
  

  Oropharynx


  Upper respiratory passages
• Anterior midline of neck from root of tongue yo trachea

  Larynx extent
• C3-C6


  Location of Larynx in male
• C1-C4


  Location of larynx in female
• Adam's apple


  Prominent angle of thyroid cartilage which makes the voice louder and low pitched
• Thyroid cartilage

  
  

  Cricoid cartilage

  
  

  Epiglottis


  unpaired cartilages of the larynx
• Arytenoid cartilage

  
  

  Corniculate cartilage

  
  

  Cuneiform cartilage


  paired cartilages of the larynx
• Thyroid cartilage


  V shaped cartilage that consists of right and left laminae
• Laryngeal prominence


  Median prominence formed by the lower parts of the anterior border of the right and left laminae of thyroid cartilage
• Thyroid notch


  Separates the upper parts of the anterior border of thyroid cart (does NOT meet)
• Thyrohyoid ligament


  Connects the greater cornua of hyoid bone to the superior cornua
• Cricothyroid joint


  Formed by the articulation of the cricoid cartilage with the inf cornua
• Conus elasticus


  Connects the cricoid cartilage with the inf border of thyroid
• Posterior border


  Free border of thyroid cartilage

  
  

  Prolonged upwards and downwards as the superior and inf cornua/horns
• Thyrohyoid

  
  

  Sternothyroid

  
  

  Thyropharyngeus part of inf constrictor of pharynx


  Attached to the oblique line of thyroid cart
• Palatopharyngeus

  
  

  Salpingopharyngeus

  
  

  Stylopharyngeus


  Connects the inf and sup cornua (insertions)
• Cricoid cartilage


  Ring shaped cartilage and is a complete cartilage

  
  

  Encircles the larynx below the thyroid cartilage and forms the foundation stone of larynx
• Cricoid cartilage


  Stronger and thicker than thyroid cart
• Arch


  Narrow anterior part of cricoid cart
• Lamina


  Broad posterior part of cricoid cart
• Cricothyroid muscle


  Ant part of the arch of cricoid gives origin to this triangular muscle which is a tensor of vocal cord
• Cricoarytenoid muscle


  Safety muscle
• lateral cricoarytenoid muscle


  Anterolateral aspect of arch gives origin to this adductor of vocal cord
• Epiglottis (epiglottic cartilage)


  Leaf shaped cartilage placed on the ant wall of the upper part of the larynx.
• Upper end of epiglottis

  Broad and free part of epiglottis, projects upward behind the hyoid bone and tongue
• thyroepiglottic ligament (lower end of epiglottis)


  Pointed and attached to the upper part of the angle between the two laminae of the thyroid cart
• Tongue

  
  

  Hyoid bone


  Ant surface of epiglottis is connected to the
• glossoepiglottic fold


  Connects tongue to epiglottis
• Hyoepiglottic ligament


  attaches the epiglottis to the hyoid bone
• Aryepiglottic muscle


  Closed inlet during swallowing
• thyroepiglottic muscle


  Attached between thyroid cartilage and margins of epiglottis

  
  

  Keeps the inlet of larynx patent for breathing
• Arytenoid cartilage


  Two small pyramid shaped cartilages on the upper border of the lamina of the cricoid cartilage
• Vocal fold

  
  

  Vocalis muscle

  Attachments of vocal process
• Vestibular fold


  Attachment above the vocal process
• posterior cricoarytenoid muscle


  Attachment of the muscular process (posterior)
• Lateral cricoarytenoid


  Attachment of the muscular process (anterior)
• transverse arytenoid muscle


  Attachment of the pos surface of Arytenoid
• Aryepiglottic muscle


  - Oblique arytenoids continues as this muscle to the 2 sides of the epiglottis
• corniculate cartilage (santorini)


  Two small conical nodules which articulate with the apex of the arytenoid cartilages

  
  

  Lie in posterior surface of the aryepiglottic folds
