Tunica Media - Vein

Vein

The middle coat is composed of a thick layer of connective tissue with elastic fibers, intermixed, in some veins, with a transverse layer of muscular tissue.

The white fibrous element is in considerable excess, and the elastic fibers are in much smaller proportion in the veins than in the arteries.

Famous quotes containing the word vein:

    As polishing expresses the vein in marble, and grain in wood, so music brings out what of heroic lurks anywhere. The hero is the sole patron of music.
    Henry David Thoreau (1817–1862)

    No man is quite sane; each has a vein of folly in his composition, a slight determination of blood to the head, to make sure of holding him hard to some one point which nature has taken to heart.
    Ralph Waldo Emerson (1803–1882)
