Women ages 30 through 65 can then be screened every 5 years with Pap and HPV cotesting or every 3 years with a Pap test alone. The guidelines also note that women with certain risk factors may need to have more frequent screening or to continue screening beyond age 65.
Petioles support leaf growth. Also called the leaf stalk, the petiole is actually an extension of the leaf in certain plants. It is the structure that connects the leaf to the stem or trunk of most vascular plants.
Introduction. 1  The stem is the major aerial support system in most plants. 2  The stem consists of the hypocotyl that leads up through the soil to the cotyledons (seed leaves). 3  Along the stem, just above each node, and in the axil (angle) of the leaf you can find lateral buds.  At the tip of the stem is the apical bud.
