Cephalization in annelids refers to the evolutionary development of a distinct head region where sensory organs and nervous tissue are concentrated. This adaptation allows for improved sensory perception and coordination, facilitating more effective movement and interaction with the environment. In annelids, the presence of a well-defined head, often with specialized structures like eyes and antennae, exemplifies this process. Overall, cephalization contributes to increased complexity and functionality in these segmented worms.
What else can I help you with?
A concentration of sense organs and nerve cells in anterior end of the body known as?
Cephalization
Does a hydra have cephalization?
A hydra does not have cephalization.
What is the cephalization of a mollusca?
The cephalization of a mollusca could possibly describe the arrangement of neurons in the front end of the animal.
Are Cnidarians in cephalization?
Cephalization means formation of a head. Cnidarians have no head, so no.
How do animals with cephalization respond differently to the environment than animals without cephalization?
Animals with cephalization respond more quickly and in more complex ways.
Do all mollusks have cephalization?
Yes. They have extensive cephalization. They have a brain and eyes.
Does the round worm have a cephalization?
they do not
Cephalization is associated with the?
nervis system
What is an animal that has no coelom and no cephalization?
A sponge.
What does cephalization refer to?
Cephalization refers to the gathering of neural tissue towards the anterior or posterior for means of central control. In arthropods, cephalization has formed the brain in the head of the animal, usually consisting of the first three ganglia of the paired nerve cords.
Which one of the following pairs represent a correct association mollusc- spider annelid- earthworm mollusc - leech annelid -octopus?
annelid- earthworm
Do nematodes show cephalization?
Phylum Nematoda does exhibit cephalization. Cephalization is a evolutionary trend in development in which the sensory and neural organs of a species becomes concentrated on one end of an organism.
