三个成分是并列的，还是后面两个是前面的同位语？

The hip houses attachments of many muscles and muscle groups. They are arranged anteriorly, medially, laterally, and posteriorly around the hip joint. Anteriorly, the rectus femoris, sartorius, iliopsoas, and pectineus are the primary flexors of the hip. The adductors longus, brevis, and magnus form the medial group responsible for adduction of the hip. The gracilis muscle is often included in this group as well.Posteriorly are the semimembranosus, semitendinosus, and the biceps femoris. Laterally, the muscles are gluteus minimus, medius, and maximus, as well as the tensor fascia lata which serve to abduct the hip.

髋部附着许多肌肉和肌肉群，并排列在髋关节的前方、内侧、外侧及后方。在前面，股直肌、缝匠肌、髂腰肌和耻骨肌是髋关节的主要屈肌。长收肌、短收肌及大收肌是髋关节内收的内侧肌群。股薄肌通常也属于内收的内侧肌群。后方是半膜肌、半腱肌及股二头肌。外侧的肌肉包括臀小肌、臀中肌及臀大肌，以及用来外展髋关节的阔筋膜张肌。

The bursae involved in hip articulation, the iliopsoas bursa and the peritrochanteric bursae, have a particularly important role from a clinical point of view. The iliopsoas bursa, the largest bursa in the human body, is bounded by the iliopsoas muscle and tendon anteriorly, the capsule of the hip posteriorly, and femoral vascular structures medially. The peritrochanteric bursae located in the subgluteus maximus region of the lateral thigh include multiple distinct bursal components. Inflammation of these bursae presents as lateral hip pain, often confused with lumbar radiculopathy.

从临床角度来看，参与髋关节活动的髂腰肌滑囊和转子周围滑囊具有特别重要的作用。髂腰肌滑囊是人体内最大的滑囊，其前部与髂腰肌和肌腱相连，后部与髋关节囊相连，内侧与股骨血管结构相连。位于大腿外侧臀大肌下方区域的转子周围滑囊包括多个不同的滑囊成分。这些滑囊的炎症表现为髋关节外侧疼痛，常与腰神经根病相混淆。

这三个成分是并列的，还是后面两个是前面的同位语，现在的翻译是把这个当同位语的，

如果是并列的，是不是这样：髋关节周围的滑囊、髂腰肌滑囊和转子周围滑囊具有特别重要的作用。
