Lecture 28 Blood Supply of upper limb Flashcards
Where does blood supply from the upper limn originate from?
- subclavian arteries
What three main arteries does the aortic arch give rise to?
- brachiocephalic artery
- left common carotid artery
- left subclavian artery
What does the brachiocephalic artery give rise to?
- right common carotid artery
- right subclavian artery
What artery passes posterior to the anterior scalene muscle and posterior to the clavicle into the axilla where it becomes the axillary artery?
- subclavian artery
What does the subclavian artery supply?
- pectoral region
- back
- posterior shoulder (scapular region)
What does the axillary artery supply?
- posterior shoulder (scapular region)
- axilla
- lateral thorax
Brachial artery supplies what?
- arm
- cubital region (elbow)
Where does the brachial artery come from?
- axillary artery
What does the brachial artery split into?
- radial artery
- ulnar artery
What does the radial artery supply?
- cubital region
- posterior forearm
- hand
What does the ulnar artery supply?
- cubital region
- anterior forearm
- hand
What are the three main branches of part one of the subclavian artery?
- internal thoracic artery
- vertebral artery
- thyrocervical arterial trunk
Where does part one of the subclavian artery lie?
- medial to the anterior scalene muscle
Where does part two of the subclavian artery lie?
- posterior to the anterior scalene muscle
Where does part three of the subclavian artery lie?
- lateral to the anterior scalene muscle
What does part two of the subclavian artery give rise to?
- costocervical trunk
- -(supreme intercostal a)
- (Deep cervical a.)
Does part three of the subclavian artery have branches?
- typically no arterial branches but sometimes dorsal scapular a. will arise here
What are the branches of the thryocervical arterial trunk?
- transverse cervical artery
- inferior thyroid artery
- ascending cervical artery
- suprascapular artery
What branch of the thyrocervical trunk gives rise to the dorsal scapular a.?
- transverse cervicle artery
sometimes the dorsal scapular a. will come off of part 3
What does the costocervical trunk give rise to?
- supreme intercostal artery
- deep cervical artery
What is the point at which the subclavian artery becomes the axillary artery?
- lateral border of first rib
Where is part one of the axillary artery in relation to the pectoralis minor muscle?
- proximal and medial
what does part one of of the axillary artery give rise to?
- superior thoracic artery
