=====Subclavian Arteries=====
Supplies blood to the thoracic limbs, neck and cranial & ventral thorax. It branches extensively, as follows:
*'''Costocervical trunk''': This is the first branch of the subclavian, it subsequently divides into the '''supreme intercostal artery''' at the level of the neck and around the withers.
*'''Deep cervical artery''': Supplies the dorsal cervical musculature in the nuchal region.
*'''Vertebral artery''': Runs in the transverse foramina of the cervical vertebrae and enters the vertebral canal at the level of the atlas. It supplies adjacent cervical musculature.
*'''Superficial cervical artery''': Supplies the base of the neck.
*'''Internal thoracic artery''': Runs just above the sternum and divides to form '''intercostal branches'''. It terminates at the level of the diaphragm, becoming the '''musculophrenic artery''' and the '''cranial epigastric artery'''.
After forming the above branches, the subclavian artery continues around the first rib to enter the thoracic limb as the '''axillary artery'''.
