-
Right Subclavian Artery arises from Brachiocephalic Artery .
-
Left Subclavian Artery arises directly from Arch of Aorta.
It is a major artery supplying thorax , shoulder , upper limb , brain and vertebrae.

Subclavian Artery
STRUCTURE AND POSITION
As both arteries arise from different arteries on each side hence they vary in shape and relations a bit.
Right Subclavian Artery arising from brachiocephalic artery is a little shorter than left one.
Left Subclavian Artery arising from arch aorta travels upwards more than right one.
Both of them are located in thorax.
RELATIONS
-
Subclavian Artery lies in Thorax.
-
Subclavian Vein accompanies it but gets separated by Anterior Scalene Muscle which lies anterior to artery.
-
Brachial Plexus is present posterosuperiorly to it.
BRANCHES
Subclavian artery is divided into 3 parts by Anterior Scalene Muscle passing anterior to it.
First part before muscle gives off three branches:
-
Vertebral Artery
-
Internal Thoracic Artery
-
Thyrocervical Trunk
Second part below muscle gives Costocervical Trunk.
Third Part after muscle gives Dorsal Scapular Artery.
Subclavian Artery terminates by forming Axillary Artery.
