The primitive pit is a depression in the center of the primitive node, connecting to the notochord. It consists of part of the primitive streak.
Famous quotes containing the words primitive and/or pit:
“Not only do our wives need support, but our children need our deep involvement in their lives. If this period [the early years] of primitive needs and primitive caretaking passes without us, it is lost forever. We can be involved in other ways, but never again on this profoundly intimate level.”
—Augustus Y. Napier (20th century)
“Come gather round me players all:
Come praise Nineteen-Sixteen,
Those from the pit and gallery
Or from the painted scene
That fought in the Post Office
Or round the City Hall....”
—William Butler Yeats (1865–1939)
