Linea Aspera - Muscles

Muscles

  • From the medial lip of the linea aspera and its prolongations above and below, the Vastus medialis originates.
  • From the lateral lip and its upward prolongation, the Vastus lateralis takes origin.
  • The Adductor magnus is inserted into the linea aspera, and to its lateral prolongation above, and its medial prolongation below.
  • Between the Vastus lateralis and the Adductor magnus two muscles are attached:
    • the Gluteus maximus inserted above,
    • and the short head of the Biceps femoris originating below.
  • Between the Adductor magnus and the Vastus medialis four muscles are inserted:
    • the Iliacus and Pectineus above;
    • the Adductor brevis and Adductor longus below.

The linea aspera is perforated a little below its center by the nutrient canal, which is directed obliquely upward.

Famous quotes containing the word muscles:

    “What is this beast, she thought,
    with muscles on his arms
    like a bag of snakes?
    What is this moss on his legs?
    What prickly plant grows on his cheeks?
    What is this voice as deep as a dog?”
    —Anne Sexton (1928–1974)

    “Light
    Flashed from his matted head and marble feet,
    He grappled at the net
    With the coiled, hurdling muscles of his thighs:
    The corpse was bloodless, a botch of reds and whites,”
    —Robert Lowell (1917–1977)

    “All of this,
    and the curious knee-cap,
    fitted above the wrought greaves,
    and the sharp muscles of your back
    which the tunic could not cover.”
    —Hilda Doolittle (1886–1961)
