  2. Subclavian groove - Wikipedia

    en.wikipedia.org/wiki/Subclavian_groove

    The rest of this surface is occupied by a groove, which gives attachment to the Subclavius; the coracoclavicular fascia, which splits to enclose the muscle, is attached to the margins of the groove. Not infrequently this groove is subdivided longitudinally by a line which gives attachment to the intermuscular septum of the Subclavius.

  3. Scalene muscles - Wikipedia

    en.wikipedia.org/wiki/Scalene_muscles

    The middle scalene arises from the posterior tubercles of the transverse processes of the lower six cervical vertebrae. It descends along the side of the vertebral column to insert by a broad attachment into the upper surface of the first rib, posterior to the subclavian groove. The brachial plexus and the subclavian artery pass anterior to it.

    The left subclavian is occasionally joined at its origin with the left common carotid artery, forming a left brachiocephalic trunk. The left subclavian artery is more deeply placed than the right in the first part of its course, and, as a rule, does not reach quite as high a level in the neck.

  8. Shoulder - Wikipedia

    en.wikipedia.org/wiki/Shoulder

    The other major sources are the transverse cervical artery and the suprascapular artery, both branches of the thyrocervical trunk which itself is a branch of the subclavian artery. [3] The blood vessels form a network (anastamosis) behind the shoulder that helps to supply blood to the arm even when the axillary artery is compromised.

  9. Subclavian nerve - Wikipedia

    en.wikipedia.org/wiki/Subclavian_nerve

    The subclavian nerve may issue a branch called the accessory phrenic nerve [3] [2] which innervates the diaphragm. [3] The accessory phrenic nerve may rather branch from the C4 or C6 segments or ansa cervicalis. [4] This nerve usually joins with the phrenic nerve before innervating the diaphragm, ventral to the subclavian vein. [5]
