Thoracoacromial artery
The thoracoacromial artery (“thoracic bone corner artery”) is an artery in the shoulder area of humans. It arises from the axillary artery, covered by the pectoralis minor muscle , and shortly afterwards divides into four branches.
| Branch | description |
| Ramus pectoralis | The ramus pectoralis descends between the pectoral muscles and branches in them. It sends branches to the mammary gland , where they anastomose with the rami intercostales of the internal thoracic artery (formerly: internal mammary artery ) and the lateral thoracic artery . |
| Ramus acromialis | It runs laterally over the coracoid process under the deltoid muscle , in which it branches. Its terminal branch pierces the muscle and ends at the acromion in a network of arteries made up of branches of the transverse scapular artery and the posterior circumflex artery . |
| Ramus clavicularis | It pulls upwards and towards the middle to the sternoclavicular joint and supplies this and the subclavian muscle . |
| Ramus deltoideus | It crosses the pectoralis minor muscle and, together with the cephalic vein, over the Mohrenheim pit into the deltopectoral sulcus . It supplies the pectoralis major and deltoideus muscles . |
