Laryngeal Membranes
Question | Answer |
---|---|
What connects the cartilages | laryngeal membranes (sheets/cords) |
What covers the surface of the larynx | a smooth mucous membrane |
What is a tracheostomy (tracheotomy) | an incision into the trachea that forms a temporary or permanent opening |
What is the opening called in a tracheotomy | stoma |
Where is the incision usually made | from the ______ to the fourth tracheal ring |
Who are all involved in a tracheotomy | SLP, physician, respiratory therapist, nurses |
Name the parts of a trach tube | Stoma, Inner Cannula, Outer Cannula, Fenestration, Cuff and Pilot ______ |
Types of trach tubes | surgical stainless steel and plastic |
Name the five layers of the vocal fold tissue | Epithelium, Superficial layer, Intermediate layer, Deep layer and Thyrovocalis muscle |
Epithelium | Gives vocal folds glistening white color (< 0.1 mm thick) |
Superficial layer | Elastin fibers (random orientation) |
Intermediate layer | ________ fibers anterior to posterior orientation |
Deep layer | collagen fibers anterior to posterior orientation |
Thyrovocalis muscle | Makes up the bulk of the vocal fold Anterior to posterior orientation |
What is the mucosal lining made of | epithelial and superficial |
Vocal Ligament is made up of | Intermediate +_______ |
Lamina Propria is made up of | Superficial + Intermediate + Deep |
Thyroarytenoid muscle is made up of two parts | thyromuscularis and thyrovocalis |
The laryngeal musculature | involves both intrinsic and extrinsic |
Intrinsic musculature | has both origin and insertion within the larynx |
Extrinsic musculature | has one attachment in the larynx and the other outside the larynx |
Intrinsic Adductors include | lateral cricoarytenoid, transverse arytenoid and oblique arytenoid |
Intrinsic Abductor is | posterior cricoarytenoid |
Intrinsic Tensors include | Cricothyroid (pars recta/pars oblique) and thyrovocalis |
Intrinsic Relaxers include | Superior thyroarytenoid and thyromuscularis |
Extrinsic Hyoid and Laryngeal elevators | Digastricus anterior, digastricus posterior, stylohyoid, mylohyoid, geniohyoid, hyoglossus, genioglossus and the inferior pharyngeal constrictor |
Extrinsic Hyoid and Laryngeal Depressors | Sternohyoid, omohyoid, sternothyroid and thyrohyoid |
Sternohyoid: | extrinsic hyoid and laryngeal depressor- function: pulls hyoid down? |
Omohyoid: | extrinsic hyoid and laryngeal depressor- place of attachment: scapula and hyoid |
Sternothyroid: | extrinsic hyoid and laryngeal depressor- place of innervation: ? |
Thyrohyoid: | extrinsic hyoid and laryngeal depressor- function: pulls larynx ____ and hyoid down |
Inferior pharyngeal constrictor | extrinsic Hyoid and Laryngeal elevator- |
Digastricus posterior | extrinsic Hyoid and Laryngeal elevator- |
