Blood Supply of the upper limb
median cubital vein
connects the basilic and cephalic vein
Venous supply of the arm
- 2 major deep veins 1. Basilic vein 2.Cephalic vein
Ulnar Artery
- larger than radial artery -passes on the medial aspect of forearm - passes between flexor carpi ulnaris and flexor digitorum profundus - not easily palpable
Radial Artery
- passes down the lateral aspect of forearm - lies immediately lateral to the large tendon of the flexor carpi radialis muscle - the radial artery leaves the forearm, passes around the lateral side of the wrist and penetrates the posterolateral aspect of the hand -palpable
Branches of the aortic arch - left side -right side
-Left side of the aortic arch: 1. Left Common Carotid Artery 2. Left Subclavian Artery -Right side of the aortic arch: 1. Brachiocephalic Artery/Trunk
Inferior vena cava (IVC)
-The inferior vena cava travels up alongside the abdominal aorta with blood from the lower part of the body. -It is the largest vein in the human body.
Superior vena cava
-The superior vena cava is above the heart, and forms from a convergence of the left and right brachiocephalic veins, which contain blood from the head and the arms.
Vena Cavae
-The venae cavae are large veins (venous trunks) that return deoxygenated blood from the body into the heart. - In humans they are called the superior vena cava and the inferior vena cava, and both empty into the right atrium. -They are located slightly off-center, toward the right side of the body.
venous supply of the hand
-hand contains interconnected network of deep and superficial veins -deep veins follow the arteries -superficial veins drain into a dorsal venous network on the back of the hand over the metacarpal bones - the cephalic vein originates over the lateral side of the dorsal venous network and passes over the anatomical snuffbox into the forearm - the basilic vein originates from the medial side of the dorsal venous network and passes into the dorsomedial aspect of the forearm
Arterial supply of the hand
-mainly by the radial and ulnar arteries which form 2 interconnected vascular arches (superficial and deep) in the palm - radial artery supplies mainly thumb and lateral side of index finger -ulnar artery supplies mainly medial side of index finger and remaining digits
Basilic vein
-medial to the brachial artery - continues as axillary vein at he lower border of teres major
Cephalic vein
-passes superior to the anterolateral aspect of the arm (basically lateral) - continues as the axillary vein
deep palmer arch
-the radial artery passes between the first 2 dorsal interossei and then between the 2 heads of the adductor pollicis to access the deep plane of the palm and form the deep arch - branches: palmer meatcarpal arteries and perforating arteries
superficial palmer arch
-the ulnar artery, from the medial side, swings laterally across the palm forming the superficial palmer arch - Branches: common and proper palmer digital arteries
What happens to the Right subclavian artery during its course
1. After crossing the 1st rib, Right subclavian artery is referred to as axillary artery 2. After crossing teres amjor, axillary artery (previously right subclavian artery) is referred to as brachial artery
Parts/Sections of the aorta
1. Ascending Aorta 2. Aortic Arch 3. Descending Thoracic aorta 4. Abdominal Aorta
Arterial supply of left arm
1. Left common carotid artery and its branches 2. Left subclavian artery and its branches
Arteries of the forearm
1. Radial Artery 2. Ulnar Artery (2 major branches of the brachial artery: The radial artery supplies the posterior aspect of the forearm and the ulnar artery supplies the anterior aspect. The two arteries anastomose in the hand, by forming two arches, the superficial palmar arch, and the deep palmar arch) http://teachmeanatomy.info/wp-content/uploads/Radial-and-Ulnar-Arteries-of-the-Forearm.jpg
Branches of the radial artery
1. Radial recurrent artery 2. Small Palmer Carpal Branch 3. larger Superficial Palmer Branch
Branches of brachiocephalic artery/trunk
1. Right common carotid artery 2. Right Subclavian artery
In general, arterial supply of the arm
1. Subclavian Arteries (left and right) 2. Carotid Arteries (left and right)
Branches of the axillary artery
1. Superior (highest/supreme) thoracic artery 2. Thoracoacromial (acromiothoracic) artery 3. Lateral thoracic artery 4. Subscapular Artery 5. Anterior circumflex humeral artery 6. Posterior circumflex humeral artery (Some Times Life Seems A Pain) 1st part- Some 2nd part- Times Life 3rd part- Seems A Pain
3 major arteries supplying the scapula
1. Suprascapular artery 2. Postrior Circumflex humeral artery 3.Circumflex scapular artery
Axillary artery 1. function 2. location 3. structure
1. function- It is responsible for carrying oxygen-rich blood to the upper limb as well as to parts of the musculocutaneous system of the scapula and upper lateral thorax 2. location- a large muscular vessel that travels through the axilla 3. Has 3 parts- 1st, 2nd and 3rd 1st part- 1 branch 2nd part- 2 branches 3rd part- 3 branches
Branches of the ulnar artery
1. ulnar recurrent artery with anterior and posteriot branches 2. common interosseous artery(divides into anterior and posterior interosseous arteries::ant. and post. to the common interosseous membrane) 3. dorsal carpal branch 4.palmer carpal branch
Branches of the brachial artery
1.Profunda brachii 2.Superior ulnar collateral artery 3.Inferior ulnar collateral artery 4.Radial artery 5.Ulnar artery https://web.duke.edu/anatomy/Lab10/images/step8g.jpg
Branches of left subclavian artery
1.vertebral artery 2. internal thoracic artery 3. thyrocervical trunk 4. costocervical trunk 5. dorsal scapular artery
Branches of the Right Subclavian artery
1.vertebral artery 2. internal thoracic artery 3. thyrocervical trunk 4. costocervical trunk 5. dorsal scapular artery
Section of the aorta giving branches to supply the chest and upper limb
Aortic arch
Arterial supply of the right arm
Brachiocephalic trunk and its branches
Branches of left common carotid artery
It splits into the external and internal carotid arteries at the upper border of the thyroid cartilage, at around the level of the fourth cervical vertebra
Branches of the Right common carotid artery
It splits into the external and internal carotid arteries at the upper border of the thyroid cartilage, at around the level of the fourth cervical vertebra
Abdominal Aorta
The abdominal aorta begins at the diaphragm, splitting to become the paired iliac arteries in the lower abdomen. Most of the major organs receive blood from branches of the abdominal aorta
Aortic Arch
The aortic arch curves over the heart, giving rise to branches that bring blood to the head, neck, and arms
Brachial Artery
The brachial artery is the major blood vessel of the (upper) arm
Importance of brachiocephalic artery/trunk
The brachiocephalic artery is an artery of the mediastinum that supplies blood to the right arm and the head and neck
Ascending Aorta
The coronary arteries branch off the ascending aorta to supply the heart with blood
Descending Thoracic Aorta
The descending thoracic aorta travels down through the chest. Its small branches supply blood to the ribs and some chest structures
axillary artery->subscapular artery->circumflex scapular artery
circumflex scapular artery is an important artery supplying the scapula
right subclavian artery->thyrocervical trunk->suprascapular artery
suprascapular artery is an important artery supplying the scapula
Continuation of the Axillary Artery
the axillary artery continues as the brachial artery
Venous supply of forearm
the deep veins of the anterior compartment generally accompany the arteries and ultimately drain into brachial veins associated with the brachial artery in the cubital fossa
Aorta
the main artery of the body, supplying oxygenated blood to the circulatory system. In humans it passes over the heart from the left ventricle and runs down in front of the backbone.
venous supply of scapula
they follow the arteries and connect with vessels in the neck,back,arm and axilla
