Larynx: Joints/Ligaments Flashcards
What is the synovial joint that is between the cricoid cartilage and the inferior horn of the thyroid cartilage?
Cricothyroid Joint
What movement does the cricothyroid joint allow for?
Rotation of the thyroid cartilage around the horizontal axis
What is the synovial joint between the cricoid cartilage and the base of the arytenoid cartilage?
Cricoarytenoid Joint
What motion does the cricoarytenoid joint allow for?
Gliding and rotation of the arytenoid cartilages on the cricoid cartilage
What is the sheet like ligament that extends from the thyroid cartilage to the hyoid bone?
Thyrohyoid Membrane
What structures will pierce the thyrohyoid membrane?
1) Internal Laryngeal Nerve
2) Superior Laryngeal Vessels
What is the ligament that extends from the arch of the cricoid cartilage to the thyroid cartilage?
