The adductor group of thigh muscles occupies the medial myofascial compartment of the thigh. This group of muscles generally originates from the pelvis and inserts on the femur. An exception, however, is the gracilis, which attaches to the proximal medial tibia as part of the pes anserine group rather than the femur. The medial compartment muscles include the following: Pectineus. Adductor longus. Adductor brevis. Gracilis. Adductor magnus (the largest muscle in the group). These muscles adduct the thigh and stabilize the pelvis, maintaining its balance during walking. The adductor magnus is the largest and most posterior of the medial thigh compartment muscles (see . Medial Compartment of the Thigh). Some consider it the most powerful and most complex of the adductor group. It divides into its adductor (pubofemoral) and hamstring (ischiocondylar) portions. This article will focus on the adductor magnus.
大腿内收肌群占据大腿内侧肌筋膜间隙。这组肌肉一般起自骨盆，止于股骨。不过，股薄肌是个例外，它作为鹅足肌群的一部分附着于胫骨近端内侧，而非股骨。内侧间隙肌肉包括：耻骨肌、长收肌、短收肌、股薄肌、大收肌（该组中最大的肌肉）。这些肌肉使大腿内收并稳定骨盆，在行走过程中保持骨盆平衡。大收肌是大腿内侧间隙肌肉中最大且最靠后的（见“大腿内侧间隙”）。有些人认为它是内收肌群中最有力且最复杂的。它分为内收（耻骨股骨）部分和腘绳肌（坐骨髁）部分。本文将重点介绍大收肌。
