The plump portion of the abdomen posterior to the petiole (and postpetiole in the Myrmicinae) is called the gaster. [3] The structure of the petiole is an easy way to visually classify ants, because the major subfamilies of Formicidae have structural differences: some ants have two-segmented petioles, while others have a single-segmented petiole.
Pedicle of vertebral arch, the segment between the transverse process and the vertebral body, and is often used as a radiographic marker and entry point in vertebroplasty and kyphoplasty procedures; Pedicle of a skin flap (medicine) Hilum of kidney, also called the renal pedicle; Pedicel, a foot process of a some cells
The pedicel is flexibly connected to the distal end of the scape and its movements in turn can be controlled by muscular connections between the scape and pedicel. The number of flagellomeres can vary greatly between insect species, and often is of diagnostic importance. [citation needed]
The difference in size and proportion between some breeds are as great as those between any wild genera, but all dogs are clearly members of the same species. [5] In 2010, a study of dog skull shape compared to extant carnivorans proposed that "The greatest shape distances between dog breeds clearly surpass the maximum divergence between ...
The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves the leaf stalk may be long (as in the leaves of celery and rhubarb), or short (for example basil). When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile.
The pedicel, between the thorax and gaster, has two segments; the petiole and postpetiole. The petiole is "hatchet-like", with a node that is almost rectangular in profile and higher than the postpetiole. The antennae have 11 segments, with the last two segments greatly enlarged into a distinct club. The antennal scape (the first segment) is ...

Petiole – a leaf stalk supporting a blade and attaching to a stem at a node. Petiolule - the leaf stalk of a leaflet. Pulvinus – the swollen base of a petiole or petiolule, usually involved in leaf movements and leaf orientation. Rachilla – a secondary axis of a multiply compound leaf. Rachis – main axis of a pinnately compound leaf.
