1·Objective: To provide anatomical basis for transferring of free musculocutaneous flap and muscular nerve branches of lateral head of triceps brachii(LHT).

目的：为肱三头肌外侧头的神经肌支移位和游离肌皮瓣移植提供解剖学基础。

2·Rat triceps brachii muscle was acquired to separate skeletal muscle satellite cells with the two-step method of collegenase-1 and trypsin and were cultured and subcultured in vitro.

取大鼠肱三头肌，采用二步消化法分离骨骼肌卫星细胞，体外进行原代培养和传代培养。
