Define the larynx -Larynx means "box" or "chest"
-Extends from the superior end of the trachea to the hyoid bone
-Includes a set of true vocal folds and false vocal folds
what is the function of the larynx -A musculo cartilaginous structure which extends from the hyoid bone to the
superior end of the trachea
-It is comprised of 3 unpaired cartilages and 3 paired cartilages
-Bound by ligaments and lined with mucous membrane
-Forms the larynx
-Larynx includes a set of true and false vocal folds
-True vocal folds
-False vocal folds
Identify the parts of the larynx
Describe the hyoid bone -Located around the 3rd cervical vertebrae
-Horseshoe-shaped bone that supports the exterior of the larynx
-Main portion is called the Corpus
-Two extensions: major and minor cornu(a)
-The major cornu(a) of the hyoid attach to the superior cornu(a) of the thyroid
cartilage
-The only bone in the body that is NOT attached to another bone
What is the function of the hyoid bone? -Horseshoe-shaped bone that supports the exterior of the larynx
-Serves as a point of attachment for several larygeal muscles
, identify the parts of the hyoid bone -Open in the posterior aspect
-3 major elements
1. Corpus (body)
Has two set of extensions, that point posteriorly
2. Greater cornu - arise from the lateral surface of the corpus and projects
posteriorly
3. Lesser cornu - more anterior projections and they project from the junction of
the greater cornu and the corpus
Name 3 paired cartilages of the larynx Arytenoids - paired
Corniculate - paired
Cuneiform - paired
Name 3 unpaired cartilages of the larynx Epiglottis - unpaired
Thyroid - unpaired
Cricoid - unpaired
Describe the parts, function, location and point of Small pyramid-shaped cartilages positioned on top of the cricoid cartilage
attachment of the Arytenoids Muscular process
Forms the place of attachment for four intrinsic muscles of the larynx
Vocal process
Forms the attachment of the vocal folds to the thyroid cartilage in front and the
attachment for the vocal ligament
describe the parts, function, location and point of -An extension of the arytenoid apex
attachment of the corniculate
describe the parts, function, location and point of -Found in the aryepiglottic folds that run from the epiglottis to the top of the
attachment of cuneiform arytenoids
-Within this tissue are two small pieces of cartilage known as the cuneiforms
describe the parts, function, location and point of -Large leaf-like structure made of elastic cartilage
attachment of the epiglottis -Extend slightly above the hyoid bone and is positioned at the base of the tongue
-Purpose: To close off the entrance to the larynx to prevent choking while
eating/drinking
