Definition
Meaning
The bony arch in the skull formed by the zygomatic bone and the temporal bone, located on the side of the head between the eye and ear.
The anatomical structure that forms the prominence of the cheek and provides a key attachment site for the masseter muscle, which is crucial for chewing.

Examples
By CEFR Level
- The boxer suffered a broken cheekbone, which doctors called a zygomatic arch fracture.
- In human anatomy, the zygomatic arch is formed by the union of processes from the temporal and zygomatic bones.
- A direct blow to the side of the face can easily fracture the delicate zygomatic arch.
- Anthropologists often measure the robustness of the zygomatic arch in hominid fossils to infer dietary habits and muscle attachment strength.
- The surgical approach involved a hemicoronal incision to access and reduce the comminuted zygomatic arch fracture.
Learning
Memory Aids
Mnemonic
Imagine a ZIG-ZAG line going over your ZYGomatic (cheek) bone, forming an ARCHway for your chewing muscles.
Conceptual Metaphor
ARCH as a structural support (like a bridge or doorway).

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation like '*зигоматическая арка*'. The standard Russian term is 'скуловая дуга' (skulovaya duga).
- Do not confuse 'arch' with 'арка' (a freestanding architectural arch); here it means 'дуга' (a curved anatomical structure).
Common Mistakes
- Mispronouncing 'zygomatic' as /zaɪˈɡɒmətɪk/ (stress on the second syllable). Correct stress is on the third syllable: /ˌzaɪɡəˈmætɪk/.
- Omitting 'arch' and just saying 'zygomatic', which refers to the bone itself, not the arched structure it helps form.
- Spelling 'zygomatic' incorrectly (e.g., 'zigomatic', 'zygomatik').

FAQ
Frequently Asked Questions
Not exactly. The cheekbone is commonly understood as the zygomatic bone. The zygomatic arch is the specific arched structure formed by that bone connecting to the temporal bone at the side of the skull.
Yes. You can feel it by placing your fingers just in front of your ear and moving them forward along the bony ridge that forms the upper border of your cheek.
It provides structural protection for the side of the eye and crucial mechanical leverage and attachment for the masseter muscle, a primary jaw-closing muscle.
Most mammals have a zygomatic arch, but its size and shape vary greatly depending on diet and jaw mechanics. It is a key feature of the mammalian skull.
