21. Muscle Cells: Postnatal Persistence
Most skeletal muscle cells are formed during early development and persist throughout life. This longevity enables muscle memory, allowing you to regain strength or skills after periods of inactivity.
However, adult muscle has a limited capacity for regeneration, relying on specialized satellite cells for minor repairs. Severe injuries or certain diseases can overwhelm this repair system, leading to lasting weakness. For more on muscle cell persistence and regeneration, visit NCBI: Muscle Regeneration.
