1. the arrangement of structures (such as nerve or muscle fibers) into small bundles or clusters
Usage: anatomy, biology
2. a visible, involuntary contraction of muscle fibers beneath the skin, often a sign of nerve or muscle disease
Usage: medicine, neurology

Examples

• The fasciculation of nerve fibers allows for organized transmission of signals throughout the body.
• Doctors observed fasciculation in the patient's leg muscles during the neurological examination.
• Muscle fasciculation can sometimes be seen as rippling movements under the skin.
• The fasciculation pattern in the spinal cord helps protect delicate nerve tissue.
• Persistent fasciculation may indicate an underlying neuromuscular disorder.
• In anatomy class, students learned how fasciculation organizes muscle tissue into functional units.
