function and location of metameric segmentation
Answers
Answer:
metameric segmentation The repetition of organs and tissues at intervals along the body of an animal, thus dividing the body into a linear series of similar parts or segments (metameres). Metameric segmentation is thought to have arisen as an adaptation to more efficient locomotion
Answer:
Metamerism is first seen in annelids in animal kingdom. Each segment usually contains appendages, muscles, nerves, blood vessels, excretory organs and a pair of coelomic sacs which are repeated in almost all segments. It is also seen in kinorhynchs, arthropods and most chordates.
features:-
1. Metamerism is always confined to the intermediate (trunk) segments except the anterior acron (head) and a posterior pygidium or telson.
2. Each metamere represents a mirror image of the other.
3. Segmental structures are interdependent on each other.
4. They are integrated into a single functional unit.
5. All the segments of body work in coordination
