百度 当然，最让人气愤的是在一次后场倒脚中，王燊超停球竟然停出了几米外！整个上半场45分钟时间，王燊超多次停球出现失误，让球迷目瞪口呆，这究竟是基本功的缺失，还是压根心思就不在比赛中？作为上港的后防核心，这样的表现，太不应该了。

The clavipectoral triangle (also known as the deltopectoral triangle) is an anatomical region found in humans and other animals. It is bordered by the following structures:

• Clavicle (superiorly)
• Lateral border of Pectoralis Major (medially)
• Medial border of Deltoid muscle (laterally)

It contains the cephalic vein, and deltopectoral fascia, which is a layer of deep fascia that invests the three structures that make up the border of the triangle. The deltoid branch of the thoracoacromial artery also passes through this triangle, giving branches to both the deltoid and pectoralis major muscles.

The subclavian vein and the subclavian artery may be accessed via this triangle, as they are deep to it.

Clinical significance

• Palpation of coracoid process of scapula

The coracoid process of the scapula is not subcutaneous; It is covered by the anterior border of the deltoid. However, the tip of the coracoid process can be felt on deep palpation on the lateral aspect of the clavipectoral triangle. The coracoid process is used as a bony landmark when performing a brachial plexus block. Position of coracoid process is significant for diagnosing dislocations as well.
