Alterations in phospholipid content of chick skeletal muscle under stress conditions

Alterations in the phospholipid levels of three gastrocnemii (G. externus, G. medius and G. internus) of chick have been studied during 56 days postembryonic growth of the three muscles. The effects of denervation and work-overload stress on their phospholipid content during the same period have been discussed in the light of denervation-induced membrane breakdown and exercise-induced fibre hypertrophy.
