Current Question (ID: 13554)

Question:

Annelids do not represent:-

Options:

1. Circumpharyngeal nerve ring
2. Longitudinal muscles in the gut
3. Metameric segmentation
4. Mesodermal pouches in body cavity

Solution:

Annelids, which are segmented worms, do not have mesodermal pouches in the body cavity. Mesodermal pouches, also known as coelomic pouches, are a characteristic feature of chordates, specifically embryonic development of vertebrates. Annelids, on the other hand, have a true coelom, which is a fluid-filled body cavity that is completely lined with mesoderm. Circumpharyngeal nerve ring, longitudinal muscles in the gut, and metameric segmentation are all characteristics of annelids. The circumpharyngeal nerve ring is a ring of nerves around the pharynx that serves as a nerve center in annelids, longitudinal muscles in the gut are responsible for the movement of food along the digestive tract, and metameric segmentation refers to the presence of repeated segments in the body of annelids.
