How to Pronounce Pectoralis Major

Say it like this: pek-tor-AL-is MAY-jor. The stress falls on the third syllable, so you emphasize the "AL" part of "pectoralis." The word "major" is said like the rank or rank in the military.

The stressed syllable is "AL" in pectoralis (pek-tor-AL-is). A common mistake is putting the stress on the first syllable and saying "PEK-tor-alis," but that's incorrect. Remember: pek-tor-AL-is MAY-jor.

Break it like this: pec-tor-a-lis ma-jor. The first word has four syllables, and the second word has two syllables. When you say it smoothly, the stress lands on the third syllable of the whole term.

Pectoralis comes from the Latin word "pectus," which means chest. Major is Latin for "greater" or "large." So pectoralis major literally means "the larger chest muscle"—it's the big one, as opposed to a smaller related muscle called the pectoralis minor.

The abbreviation is "pec major" or sometimes just "pecs." You say "pec major" as "pek MAY-jor." The word "pecs" is very common in everyday language when people talk about chest muscles.

It's the large, fan-shaped muscle across the front of your chest. Think of it as your main chest muscle—the one involved in pushing movements like when you do a push-up or push a door open.

Pectoralis minor is another chest muscle, but it's smaller and located underneath. Both words use the Latin root "pectus" (chest), so you'll recognize the "pectoralis" part in both terms. You say pectoralis minor as "pek-tor-AL-is MY-nor."

Sure! Here's an example: "The pectoralis major is the muscle you feel when you push against something with your arm." Or: "Doctors and athletes often refer to the pectoralis major when discussing chest strength."
