Larynx

The larynx plays a critical role in speech.

- - pseudostratified columnar epithelium with cilia and goblet cells.
  - - basal bodies visible as a dark line at the base of the cilia.
  - - clear, oval structures with heterochromatic nuclei adjacent to ciliated, columnar cells.
  - - an amorphous thick, pink band at the base of the epithelium.
- - add moisture to air and aid in trapping contaminants.
- a lateral diverticulum that separates false folds above from true vocal cords below.
- - thick band of connective tissue within the lamina propria near the surface of the vocal cord.
  - - covers this region of the larynx because it is subject to mechanical stress.
- - skeletal muscle that underlies and regulates the tension of the vocal ligament.
- - covers the true vocal cord except for the region that covers the vocal ligament.
- - add moisture to air and aid in trapping contaminants.
