1. The Larynx

2. Larynx -organ that provides a protective sphincter at the inlet of the air passages -responsible for voice production -opens above into the laryngopharynx, and below with the trachea -covered in front by the infrahyoid strap muscles and at the sides by the thyroid gland

3. Location -situated below the tongue and hyoid bone, between the great blood vessels of the neck -lies at the level of the 4 th , 5 th , and 6 th cervical vertebrae

7. -Each cartilage has: • apex- articulates with the small corniculate cartilage • vocal process - projects forward and gives attachment to the vocal ligament • muscular process - projects laterally & gives attachment to the posterior and lateral cricoarytenoid

24. -moves with respiration • Rima glottidis/glottis - gap between the vocal folds; narrowest part of the larynx and measures about 2.5 cm from front to back in the male adult and less in the female. In children, the lower part of the larynx within the cricoid cartilage is the narrowest part

27. Sinus of the Larynx - paired small recesses lined with mucous membrane between the vestibular and vocal folds Saccule of the Larynx - a diverticulum of mucous membrane that ascends from the sinus; mucous secretion lubricates the vocal cords

29. Muscles of the Larynx • Elevation: Digastric Stylohyoid Mylohyoid Geniohyoid Stylopharyngeus Salpingopharyngeus Palatopharyngeus • Depression: Sternothyroid Sternohyoid Omohyoid
