jugal bone
C2Technical, Scientific
Definition
Meaning
A facial bone in the skull that forms the prominence of the cheek.
In comparative anatomy and palaeontology, a homologous bone in the skulls of other vertebrates, such as reptiles, that contributes to the cheek structure.
Linguistics
Semantic Notes
The term is almost exclusively used in anatomy, zoology, and palaeontology. It is synonymous with 'zygomatic bone' in human anatomy but is the preferred term for non-mammalian vertebrates. 'Zygomatic arch' refers to the entire structure formed by the jugal bone and parts of the temporal bone.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage. Both use 'jugal bone' in scientific contexts. 'Zygomatic bone' is the more common clinical term in human anatomy in both regions.
Connotations
Neutral scientific term in both varieties.
Frequency
Extremely low frequency in general language. Used equally rarely in specialized texts in both UK and US English.

Examples
By Part of Speech
adjective
British English
- The jugal arch was complete in the fossil.
- Jugal morphology varies between species.
American English
- The jugal arch was complete in the fossil.
- Jugal morphology varies among species.
Examples
By CEFR Level
- In human anatomy, the jugal bone is more commonly called the zygomatic bone.
- The boxer suffered a fracture to his jugal bone.
- The palaeontologist noted the unusually robust jugal bone, suggesting powerful jaw muscles in the dinosaur.
- The jugal bone articulates with the maxilla, squamosal, and postorbital bones in many reptiles.
Learning
Memory Aids
Mnemonic
JUGAL sounds like 'juggler'. Imagine a juggler balancing a BONE on his CHEEK. Jugal bone = cheek bone.
Conceptual Metaphor
A BUILDING BLOCK or ANCHOR POINT for facial structure.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'jaw bone' (челюстная кость). The jugal/zygomatic bone is specifically the скуловая кость.
- Avoid direct translation like 'югальная кость'. It is not a standard Russian term; use 'скуловая кость'.
Common Mistakes
- Pronouncing it as /dʒʌɡəl/ (like 'juggle'). Correct is /ˈdʒuːɡl̩/.
- Using it in everyday conversation instead of 'cheekbone'.
- Confusing it with the 'temporal bone'.

FAQ
Frequently Asked Questions
Yes, but 'jugal bone' is the precise anatomical term, while 'cheekbone' is the everyday, lay term. In human anatomy, 'zygomatic bone' is the standard clinical term.
No. It is a bone found in the skulls of many vertebrates, including reptiles and mammals, but its presence, size, and shape vary significantly across different species.
You would only use it in highly specialized contexts like academic research in anatomy, zoology, palaeontology, or possibly in certain medical or veterinary discussions. It is not a word for general use.
The jugal bone (or zygomatic bone) is one of the bones that forms the cheek. The zygomatic arch is the complete bony arch on the side of the skull, formed by the jugal/zygomatic bone and a process of the temporal bone.
