Wherever they occur, skeletal muscles are connected to the somatic nervous system, which gives us almost complete control over their movements.

不管它们存在于哪里，骨骼肌都被连接到身体的神经系统，这几乎给了我们完整的活动控制权。

The basic route of the efferent somatic nervous system includes a two neuron sequence.

传出躯体神经系统的基本通路包括一个二级神经元序列。

They're striated like cardiac muscle tissue, but they're also mostly voluntary, meaning you have to think about using them and activate them with your somatic nervous system.

它们像心肌组织一样有条纹，但也大多是自愿的，这意味着你必须考虑使用它们，并用你的躯体神经系统激活它们。

The somatic nervous system consists of afferent fibers that receive information from external sources, and efferent fibers that are responsible for muscle contraction.

躯体神经系统由接收外界信息的传入纤维和负责肌肉收缩的传出纤维组成。
