Verified step by step guidance1
Identify the word 'cortex' as a noun of Latin origin, which often follows specific pluralization rules based on its ending.
Recognize that 'cortex' ends with the suffix '-ex', which commonly changes to '-ices' in the plural form for many Latin-derived medical terms (e.g., 'index' becomes 'indices').
Apply this rule to 'cortex' by replacing the '-ex' ending with '-ices' to form the plural.
Confirm that the plural form is 'cortices', which is the medically and linguistically correct plural of 'cortex'.
Review the other options and note that 'corteces', 'corteice', 'cortias', and 'cortexes' do not follow the standard Latin pluralization rules for this term.
