Internal Thoracic Artery - Branches

Branches

  • Mediastinal branches
  • Thymic branches
  • Pericardiacophrenic artery - travels with the phrenic nerve
  • Sternal branches
  • Perforating branches
  • Twelve anterior intercostal branches, two to each of the top six intercostal spaces. In a given space, the upper branch travelling laterally along the bottom of the rib until it anastomoses with its corresponding posterior intercostal artery. The lower branch of the space anastomoses with a collateral branch of the posterior intercostal artery.

After passing the sixth intercostal space, the internal thoracic artery splits into the following two terminal branches:

  • Musculophrenic artery - roughly follows the costal margin
  • Superior epigastric artery - continues the course of the internal thoracic artery, travelling downward into the abdominal wall

Famous quotes containing the word branches:

    “I couldn’t afford to learn it,” said the Mock Turtle with a sigh. “I only took the regular course.”
    “What was that?” inquired Alice.
    “Reeling and Writhing, of course, to begin with,” the Mock Turtle replied; “and then the different branches of Arithmetic—Ambition, Distraction, Uglification, and Derision.”
    “I never heard of ‘Uglification,’” Alice ventured to say.
    Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)

    They all came, some wore sentiments
    Emblazoned on T-shirts, proclaiming the lateness
    Of the hour, and indeed the sun slanted its rays
    Through branches of Norfolk Island pine as though
    Politely clearing its throat....
    John Ashbery (b. 1927)

    Think how stood the white pine tree on the shore of the Chesuncook, its branches soughing with the four winds, and every individual needle trembling in the sunlight,—think how it stands with it now,—sold, perchance, to the New England Friction-Match Company!
    Henry David Thoreau (1817–1862)
