ANTIMERE Meaning and
Definition
-
Antimere is a term used in biology, particularly in the study of anatomy and development, to describe one of the two symmetrical halves or segments that are divided by a midline or axis. It refers to the right and left halves of a bilateral organism or structure that are mirror images of each other. In other words, antimeres are equivalent halves that exhibit a symmetrical arrangement.
The concept of antimere is commonly applied to describe the body regions of arthropods, for instance, insects and crustaceans. These organisms typically have a bilateral body plan, and their bodies can be divided into two equivalent halves along a midline or sagittal plane. Each half of the body is referred to as an antimere. For instance, the head, thorax, and abdomen of an insect can each be considered as three antimeres.
Antimeres are not only observed in overall body plans but can also describe specific structures within an organism. For example, limbs such as legs or wings can be divided into antimeres, as they exhibit a symmetrical arrangement from left to right. This concept allows for the systematic description and study of bilateral symmetry, as well as the developmental processes that lead to the formation of symmetric structures.
In conclusion, antimere refers to one of the two symmetrical halves or segments of a bilateral organism or structure. It is a fundamental concept in biological sciences that aids in understanding the symmetry and organization of living organisms.

Etymology of ANTIMERE
The word "antimere" is derived from the Greek roots "anti-" meaning "opposite" or "against", and "meros" which means "part" or "half". Combining these roots, "antimere" literally translates to "opposite part" or "against part", indicating a counterpart or opposite half. In biology, specifically in zoology and embryology, "antimere" refers to the corresponding or mirrored halves of bilateral organisms or structures.
