C2Technical/Medical
Definition
Meaning
A group of muscles innervated by a single spinal nerve segment.
In embryology, a segment of the paraxial mesoderm that develops into the skeletal muscles of the body; also used to describe the muscle mass derived from one somite.
Linguistics
Semantic Notes
The term is highly specific to anatomy and embryology. It refers to both a developmental structure and a functional neurological unit. It is not used in general language.

Examples
By Part of Speech
adjective
British English
- The myotomal distribution of weakness was clear.
- Myotome testing is part of the neurological exam.
American English
- The myotomal pattern indicated the level of spinal injury.
- Myotome assessment is standard procedure.
Examples
By CEFR Level
- The doctor tested the strength of each myotome to locate the nerve damage.
- In the developing embryo, each somite differentiates into a sclerotome, a dermatome, and a myotome.
- Weakness in the C5 myotome, which includes the deltoid and biceps, suggests a problem at that specific cervical nerve root.
Learning
Memory Aids
Mnemonic
Think 'MYO-' (muscle) + '-TOME' (a cutting or segment), like a segment of muscle served by one nerve.
Conceptual Metaphor
A myotome is like an electrical circuit serving a specific set of appliances (muscles), with the spinal nerve as the single cable.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'миотом' (direct equivalent, but a false friend in terms of common usage). The Russian word is equally technical and not used in general speech. Avoid associating it with more common words like 'мышца'.
Common Mistakes
- Mispronouncing it as 'myo-tome' (with a hard 'tome' as in book). The stress is on the first syllable: MY-o-tome.
- Using it in a non-medical context.
- Confusing it with 'myotome' as a surgical instrument (a different, rare homograph).

Frequently Asked Questions
No, it is a highly specialised term used only in medical, anatomical, and biological contexts.
No, it is exclusively a noun. The related adjective is 'myotomal'.
A myotome refers to muscles innervated by a single spinal nerve, while a dermatome refers to the area of skin supplied by a single spinal nerve.
Absolutely not. It is relevant only for healthcare professionals, anatomists, or advanced biology students.
