Greater Trochanter - Borders

Borders

The superior border is free; it is thick and irregular, and marked near the center by an impression for the insertion of the piriformis.

The inferior border corresponds to the line of junction of the base of the trochanter with the lateral surface of the body; it is marked by a rough, prominent, slightly curved ridge, which gives origin to the upper part of the vastus lateralis.

The anterior border is prominent and somewhat irregular; it affords insertion at its lateral part to the glutæus minimus.

The posterior border is very prominent and appears as a free, rounded edge, which bounds the back part of the trochanteric fossa.

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)

    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)

    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)
