Summary
Hereditary factors significantly influence anomalous innervation of the extensor digitorum brevis muscle by the accessory deep peroneal nerve. This suggests a potential dominant inheritance pattern for this common anatomical variation.
Area of Science:
- Anatomy
- Genetics
- Neuroscience
Background:
- Anomalous innervation of the extensor digitorum brevis muscle is a known anatomical variation.
- The accessory deep peroneal nerve's role in this variation requires further investigation.
Purpose of the Study:
- To investigate the hereditary basis of anomalous innervation of the extensor digitorum brevis muscle by the accessory deep peroneal nerve.
- To determine the potential inheritance pattern of this anatomical variation.
Main Methods:
- Electrophysiological techniques were employed to assess nerve function.
- A cohort of 100 healthy, unrelated individuals was studied.
- Family members of individuals with the anomalous innervation were also examined.
Main Results:
- A significant prevalence (22%) of anomalous innervation was observed in the healthy cohort.
- Individuals with the anomalous innervation showed a high rate (78%) of this variation among their relatives.
- Data indicate a strong familial aggregation of this anomalous innervation.
Conclusions:
- Hereditary factors appear to play a substantial role in the occurrence of anomalous innervation of the extensor digitorum brevis muscle.
- A dominant mode of inheritance is suggested for this variation.
- Further genetic studies are warranted to confirm the inheritance pattern.
