If you are saying something that belongs to the larynx, as in "the larynx's cartilage protects the throat" then you use apostrophe S.
No, the correct term is "larynx" without an apostrophe s. The larynx is a part of the throat that contains the vocal cords and plays a key role in producing sound.
Use 's when indicating possession or contraction (e.g. Sarah's cat, it's sunny) and use s' to show possession for plural nouns (e.g. the students' desks).
Use 's to indicate the possessive form of singular nouns, such as "Tom's car." Use s' to indicate the possessive form of plural nouns ending in s, such as "the boys' bikes."
Use 's to form the possessive of singular nouns (e.g. dog's) and use -ies to form the plural of words ending in a consonant and y (e.g. babies).
An 's preceded by an apostrophe ('s) indicates possession or contraction (e.g., John's book, it's raining). An s followed by an apostrophe (s') is used for plural possessives where the noun is already plural (e.g., the girls' toys).
s' is used as an apostrophe for a word that refers to plural form, for example saying The girls' toys. In this instance it refers to the toys of more than one girl. You would also use s' for names ending with an s, such as Tess' toys. 's is used as an apostrophe for a word that refers to singular form, for example saying The girl's toys. This refers to the toys of just one girl. You would also use 's with names such as Tom's toys
