荐尾[尾骨]背外侧肌
Musculus sacrocaudalis [-coccygeus] dorsalis lateralis
定义
起点： 为最长肌的延续，以肉质起自最长肌腱膜，并以腱性起点起自第一至第六腰椎乳突、荐骨关节突，以及至少前八块尾椎的乳突。
止点： 第五块至最后一块尾椎的乳突。
功能： 伸展或上提尾部，可能亦参与尾部侧向运动。
神经： 尾背侧丛的分支。
变异：
在马属动物中，荐尾[尾骨]背外侧肌发育良好，其起点（位置较荐尾[尾骨]背内侧肌更偏颅侧）经腱膜板起自最后一块腰椎乳突，起自前三块荐椎棘突的中间部分，以及起自最后两块荐椎乳突的基部。第一肌束较长，止于第九块尾椎的乳突。每一肌束均终止于一条长腱，该长腱与荐尾[尾骨]背内侧肌的肌腱共用，延伸至最后一块椎骨。
