| superior pole | For a structure having a vertically oriented long axis, the point at the upper end of the axis, furthest from the soles of the feet; the highest point of a structure's surface. See: superior pole of kidney, superior pole of testis. Synonym: extremitas superior, superior extremity. (05 Mar 2000) |

| abapical pole | In an ovum, the pole opposite the animal pole (i.e., vegetal pole). (05 Mar 2000) |
| animal pole | <cell biology> In most animal oocytes the nucleus is not centrally placed and its position can be used to define two poles. That nearest to the nucleus is the animal pole and the other is the vegetal pole, with the animal vegetal axis between the poles passing through the nucleus. During meiosis of the oocyte the polar bodies are expelled at animal pole. In many eggs there is also a graded distribution of substances along this axis, with pigment granules often concentrated in the animal half and yolk, where present, largely in the vegetal half.

| anterior pole of eyeball | The centre of the corneal curvature of the eye. Synonym: polus anterior bulbi oculi. (05 Mar 2000) |
| anterior pole of lens | The central point on the anterior surface of the lens of the eye. Synonym: polus anterior lentis. (05 Mar 2000) |
| vegetal pole | Of vertebrate eggs. The surface of the egg opposite to the animal pole. Usually the cytoplasm in this region is incorporated into future endoderm cells. (18 Nov 1997) |
| vegetative pole | The part of a telolecithal egg where the bulk of the yolk is situated. (05 Mar 2000) |
| germinal pole | <cell biology> In most animal oocytes the nucleus is not centrally placed and its position can be used to define two poles. That nearest to the nucleus is the animal pole and the other is the vegetal pole, with the animal vegetal axis between the poles passing through the nucleus. During meiosis of the oocyte the polar bodies are expelled at animal pole. In many eggs there is also a graded distribution of substances along this axis, with pigment granules often concentrated in the animal half and yolk, where present, largely in the vegetal half.
