Why don't muscle cells burst when you exercise?

  1. Apr 2, 2010 #1
    One way muscle grows is muscle hypertrophy where sarcoplasmic fluid increases inside the muscle cell. Wouldn't this burst the cell membrane, I can understand how organelles can replicate but what about the cell membrane. I know this sounds like a stupid question but please help. Thanks :smile:

    lipids are the main component of cell membrane. I think as muscle grows cell membrane lipids are synthesized and they simply join the pre-existing membrane and increase it's surface to resist cell rupture.

    Yes for the time being I'll think like that. Thanks :smile:
