Scapula - Structure - Borders

Borders

There are three borders of the scapula:

  • The superior border is the shortest and thinnest; it is concave, and extends from the medial angle to the base of the coracoid process. It is referred to as the cranial border in animals.
  • The axillary border (or "lateral border") is the thickest of the three. It begins above at the lower margin of the glenoid cavity, and inclines obliquely downward and backward to the inferior angle. It is referred to as the caudal border in animals.
  • The vertebral border (or "medial border") is the longest of the three, and extends from the medial to the inferior angle. It is referred to as the dorsal border in animals.

Famous quotes containing the word borders:

    Love works at the centre,
    Heart-heaving alway;
    Forth speed the strong pulses
    To the borders of day.
    Ralph Waldo Emerson (1803–1882)

    The bugle-call to arms again sounded in my war-trained ear, the bayonets gleamed, the sabres clashed, and the Prussian helmets and the eagles of France stood face to face on the borders of the Rhine.... I remembered our own armies, my own war-stricken country and its dead, its widows and orphans, and it nerved me to action for which the physical strength had long ceased to exist, and on the borrowed force of love and memory, I strove with might and main.
    Clara Barton (1821–1912)

    Let the man stand on his feet. Let religion cease to be occasional; and the pulses of thought that go to the borders of the universe, let them proceed from the bosom of the Household.
    Ralph Waldo Emerson (1803–1882)
