A part of the territory is posterior and inferior going up to the anterior pole of the central complex.

They have a lid-like structure called an operculum at the anterior pole, from which the nymph emerges during hatching.

The eye acts as a dipole in which the anterior pole is positive and the posterior pole is negative.

The posterior region (including the hindgut) expands and extends towards the anterior pole along the dorsal side of the embryo.

The anterior pole is bluntly pointed, while the posterior pole is blunted Blepharisma.

Numb is distributed uniformly in the cytoplasm until mitotic division, when it is selectively localized to the anterior pole of the cell.

The lens fibers stretch lengthwise from the posterior to the anterior poles and, when cut horizontally, are arranged in concentric layers rather like the layers of an onion.

The veins at the anterior poles of the thalami merge posterior to the pineal gland to form the Great Cerebral Vein of Galen.

The new fibers grow longer than those of the primary layer, but as the lens gets larger, the ends of the newer fibers cannot reach the posterior or anterior poles of the lens.

Higher magnitude order multipole fields may dominate closer to the fish, where the current does not converge on one point for the anterior pole but makes a perpendicular gradient over the length of the fish.

In the sensory organ precursor (SOP) cell, the PAR proteins localize to the posterior pole of the cell, and the Pins/GαI complex is localized to the anterior pole of the cell.
