How to Pronounce Cortical Bone

Cortical bone is pronounced KOR-tih-kal bohn. Say it like "KOR" (rhymes with "for"), then "tih" (rhymes with "uh"), then "kal" (rhymes with "pal"), and finish with "bohn" (rhymes with "cone"). The stress falls on the first syllable, KOR.

The stressed syllable is the first one: KOR. A common mistake is stressing the second syllable and saying kor-TIH-kal, but the correct way puts the emphasis on KOR-tih-kal.

The word cortical breaks into three syllables: COR-ti-cal. When you say it slowly, you pause briefly after each syllable. The full term cortical bone is four syllables total: COR-ti-cal bone.

Cortical means "outer layer" or "outer shell." When doctors use the word cortical, they're talking about something that forms the outer covering of a structure—in this case, the outer covering of a bone.

The word cortical comes from the Latin word cortex, which means "bark" or "outer layer." Just like bark is the outer covering of a tree, cortical bone is the outer layer of human bones.

Several medical words share the cortex/cortical root, including cerebral cortex (the outer part of the brain), cortisol (a hormone), and renal cortex (the outer part of the kidney). They all refer to outer layers of different body structures.

Here's an example: "The doctor explained that cortical bone forms the hard outer shell of the femur." This shows how the term is used when talking about bone structure.

Yes—doctors sometimes just say "cortical" when the context already makes clear they're talking about bone. You might also hear it called "compact bone," which means the same thing and uses simpler words.
