(n.) A piece in the form of the sector of a circle, or part of a ring; as, the segment of a sectional fly wheel or flywheel rim.
(n.) A segment gear.
(n.) One of the cells or division formed by segmentation, as in egg cleavage or in fissiparous cell formation.
(n.) One of the divisions, rings, or joints into which many animal bodies are divided; a somite; a metamere; a somatome.
(v. i.) To divide or separate into parts in growth; to undergo segmentation, or cleavage, as in the segmentation of the ovum.

Strobila
Definition:
(n.) A form of the larva of certain Discophora in a state of development succeeding the scyphistoma. The body of the strobila becomes elongated, and subdivides transversely into a series of lobate segments which eventually become ephyrae, or young medusae.
(n.) A mature tapeworm.
