The sciatic nerve was crushed in rats at different times during the first two weeks after birth. Following reinnervation the recovery of the fast and slow muscles and their motoneurones was compared. The main factor affecting recovery of muscle weight and tension was the age at which the nerve was crushed; the earlier the injury the greater the impairment. However, recovery also depended upon muscle type. The fast muscles, tibialis anterior and extensor digitorum longus, always recovered less… CONTINUE READING
