    Study Notes

    Blood Flow Through the Upper Limb

    Left Ventricle to Aortic Arch

    • Blood flows from the left ventricle into the ascending aorta
    • The ascending aorta travels upwards and arches, forming the aortic arch

    Aortic Arch and Branches

    • Three main vessels branch off from the aortic arch:
      • Brachiocephalic trunk (right)
      • Left common carotid artery
      • Left subclavian artery

    Brachiocephalic Trunk and Branches

    • The brachiocephalic trunk splits into:
      • Right subclavian artery
      • Right common carotid artery

    Right Subclavian Artery and Branches

    • The right subclavian artery gives off:
      • Thyroid cervical branch
      • Vertebral branch
      • Internal thoracic branch
    • Continues as the axillary artery

    Axillary Artery and Branches

    • The axillary artery gives off:
      • Subscapular artery
      • Posterior circumflex humeral artery
      • Anterior circumflex humeral artery
    • Continues as the brachial artery

    Brachial Artery and Branches

    • The brachial artery gives off:
      • Deep brachial artery
      • Radial artery
      • Ulnar artery

    Radial and Ulnar Arteries

    • The radial and ulnar arteries communicate with each other, forming:
      • Dorsal carpal arch
      • Deep palmar arch
      • Superficial palmar arch

    Dorsal Carpal Arch and Branches

    • The dorsal carpal arch gives off:
      • Dorsal metacarpal arteries
      • Dorsal digital arteries

    Deep and Superficial Palmar Arches

    • The deep palmar arch gives off:
      • Palmar metacarpal arteries
    • The superficial palmar arch gives off:
      • Common palmar digital arteries
    • The palmar metacarpal arteries anastomose with the common palmar digital arteries

    Proper Palmar Digital Arteries and Anastomosis

    • The common palmar digital arteries branch into:
      • Proper palmar digital arteries
    • Anastomosis occurs between the dorsal digital arteries and the proper palmar digital arteries, forming the oblique into capitulo arteries

    Blood Flow Through the Upper Limb

    From Left Ventricle to Aortic Arch

    • Blood flows from the left ventricle into the ascending aorta
    • The ascending aorta arches, forming the aortic arch

    Aortic Arch and Its Branches

    • The aortic arch gives off three main vessels:
      • Brachiocephalic trunk (right)
      • Left common carotid artery
      • Left subclavian artery

    Brachiocephalic Trunk and Its Branches

    • The brachiocephalic trunk splits into:
      • Right subclavian artery
      • Right common carotid artery

    Right Subclavian Artery and Its Branches

    • The right subclavian artery gives off:
      • Thyroid cervical branch
      • Vertebral branch
      • Internal thoracic branch
    • Continues as the axillary artery

    Axillary Artery and Its Branches

    • The axillary artery gives off:
      • Subscapular artery
      • Posterior circumflex humeral artery
      • Anterior circumflex humeral artery
    • Continues as the brachial artery

    Brachial Artery and Its Branches

    • The brachial artery gives off:
      • Deep brachial artery
      • Radial artery
      • Ulnar artery

    Radial and Ulnar Arteries

    • The radial and ulnar arteries communicate with each other, forming:
      • Dorsal carpal arch
      • Deep palmar arch
      • Superficial palmar arch

    Dorsal Carpal Arch and Its Branches

    • The dorsal carpal arch gives off:
      • Dorsal metacarpal arteries
      • Dorsal digital arteries

    Deep and Superficial Palmar Arches

    • The deep palmar arch gives off:
      • Palmar metacarpal arteries
    • The superficial palmar arch gives off:
      • Common palmar digital arteries
    • The palmar metacarpal arteries anastomose with the common palmar digital arteries

    Proper Palmar Digital Arteries and Anastomosis

    • The common palmar digital arteries branch into:
      • Proper palmar digital arteries
    • Anastomosis occurs between the dorsal digital arteries and the proper palmar digital arteries, forming the oblique into capitulo arteries
