人体哪些肌肉属于骨骼肌 龚爱平 徐州矿务集团总医院
人体的肌肉分为心肌、平滑肌、横纹肌三类，其中，横纹肌多数呈圆索性，大多跨越关节而附着于骨骼等部位，故又名骨骼肌。骨骼肌分布于四肢、颈、肩、胸、腰、背、喉咽部、眼球外及面部等处，人体大约有600多块骨骼肌，通俗地讲，各种各样的骨构成支架，骨连接将这些骨连接起来，而骨骼肌附在骨外面，正是由于骨骼肌的牵拉收缩，骨才能运动。所以，骨骼肌属于人体运动系统，是横纹肌。

Which muscles of human body belong to skeletal muscle
The muscles of human body are divided into three categories: myocardium, smooth muscle and striated muscle, Among them, Most of the striated muscles are round, Most of them are attached to bones and other parts across joints, It is also called skeletal muscle. Skeletal muscles are distributed in limbs, neck, shoulder, chest, waist, back, laryngopharynx, extraocular and facial areas, There are more than 600 skeletal muscles in the human body, Generally speaking, All kinds of bones form scaffolds, Bone connections connect these bones, The skeletal muscle is attached to the bone, It is because of the traction and contraction of skeletal muscle, Bones move. So, Skeletal muscle belongs to human motion system, It's the striated muscle.
