A 
Left Subclavian 
Right Subclavian 
\+ Truncus bicaroticus comes of the 
TRUNCKUS BRACHIOCEPHALLICUS

Q

Vertebral artery

A

passes cranially through the transverse canal formed by the transverse foramina of the cervical vertebrae, enters vertebral canal within the atlas.

Muscular branches to cervical muscles and spinal branches to the vertebral canal

In ox= also supply caudal portion of the brain. nb religious slaughtering.

Q

The internal thoracic artery

A

runs caudally above sternum and detaches the intercostal branches.
It ends at the diaphragm, where it decides into:
A.Musculophrenica: supplying diaphragm and
A. epigastrica cranialis (passes to the stomach, anastomoses with caudal epigastric)

Q

When does the Subclavian Artery become the A.axillaris?

A

After detaching branches (a.cervicalis superficialis and A.Thoracica interna) it winds around the cranial border of the first rib, to enter the forelimb.
