American and British English spelling differences caecum?

The word you're asking about is actually cecum, not "caecum". Here's the breakdown of the spelling difference:

* American English: cecum

* British English: caecum

The difference lies in the presence or absence of the letter "a" before the "e". This is a common spelling variation between American and British English, often found in words of Latin origin.

It's important to note that both spellings refer to the same anatomical structure: the first part of the large intestine.
