ARYTENOID CARTILAGE
- Arytenoid cartilage
- shape
- pyramid shaped cartilages
- apex
- curved posteromedially
- articulates with corniculate cartilage
- base
- concave
- articulates with
- lateral part of upper border of cricoid lamina
- prolonged anteriorly to form
- vocal process
- vocal fold is attached here
- vocalis muscle also attaches
- Above vocal process
- vestibular fold is attached
- prolonged laterally to form
- muscular process
- posterior aspect gives insertion to
- posterior cricoarytenoid
- anterior aspect gives insertion to
- lateral cricoarytenoid
- surfaces
- anterolateral
- medial
- posterior
- transverse arytenoid across two cartilages
- between base and apex
- oblique arytenoid
- continues as aryepiglottic muscle in to two sides of epiglottis
- situation
