costoclavicular ligament – band of connective tissue that unites the medial clavicle with the initial rib.

axillary artery – continuation from the subclavian artery as it penetrates the body wall and enters the axillary location; materials blood to the area close to The top from the humerus (humeral circumflex arteries); virtually all the vessel carries on in to the brachium and gets to be the brachial artery.
