- ‘Clinically, there was no muscle atrophy, pain, or fasciculation; a muscle biopsy showed only mild myofiber atrophy.’
- ‘The affected muscles show fasciculations that are rippling contractions seen through the skin or in the tongue.’
- ‘Shortly into my neurophysiological assessment, normally recruiting muscles confirmed a diagnosis of benign fasciculations.’
- ‘Local sweating and fasciculation of local muscle groups may occur initially after skin absorption of liquid or vapour.’
- ‘The muscle is contracted and hard, and an observer can see fasciculation - small twitchings - over its surface.’
Arrangement in bundles.
- ‘It is important to note that the aberrant projections do not seem to result from fasciculation defects or growth impairments.’
- ‘This phenotype may be the result of defective interaxon communication that obstructs axon extension or fasciculation in the longitudinal pathways.’
