In Netter's the lower border of laryngopharynx

in Netter’s the lower border of laryngopharynx is before the origin of cricoid cartilage…whereas in your lectures you said it extends till the lower border of cricoid cartilage…maam i got confused here…please clear this doubt maam.

Trachea starts below the lowers border of cricoid cartilage. So lowermost part of larynx has to be at the level of cricoid cartilage. And part of pharynx corresponding to larynx is laryngopharynx. So laryngopharynx extends to lower border of cricoid cartilage.

It will be lower border C6 or cricoid cartilage…that is lower Border of hypopharynx…
