What is the advantage of having a head with a concentration of sensory organ?

Development of a Brain An obvious advantage of cephalization is the development of a control center or brain. The brain is a concentration of nervous tissue that coordinates and controls sensory information and nervous activity. A larger brain allows for smarter and more complex animals.

What are the possible advantages of an animal having an anterior head with a concentration of sense organs and nervous tissue?

Advantages of cephalization are development of a complex neural system and intelligence, clustering of senses to help an animal rapidly sense food and threats, and superior analysis of food sources. Radially symmetrical organisms lack cephalization.

Why would sensory structures be focused concentrated in the front of the animal?

Organisms with cephalization have a defined head area. This adaptation allows organisms to concentrate their sensory organs towards the front of their bodies, allowing them to preferentially sense the area in front of them rather than the area behind them.

How is Cephalisation advantageous to animals in finding food?

The cephalisation advantageous to animals in finding food of cephalization which is provide better control and develop the centre part or in the brain. Here the brain is concentration of nervous tissues which coordinate as well as control senory information as well as the nervous activity.

How is cephalization adaptive?

Cephalization is thought to be an evolutionary adaptation resulting from the tendency of bilaterally symmetrical animals to move forward, so that information about newly encountered parts of the environment impinges first on the front of the animal.

Is there an advantage to having a brain at the anterior end of the body?

Concentration of Sense Organs

Well, animals with heads move in the direction of their anterior end. ... So, having the sense organs also at this end allows animals to experience and respond to their environment more efficiently.

What is the advantage of cephalization in arthropods?

Arthropods. In arthropods, cephalization progressed with increasing incorporation of trunk segments into the head region. This was advantageous because it allowed for the evolution of more effective mouth-parts for capturing and processing food.

Why are sensory receptors important?

A major role of sensory receptors is to help us learn about the environment around us, or about the state of our internal environment. Different types of stimuli from varying sources are received and changed into the electrochemical signals of the nervous system.

Why is sensory adaptation important in animals?

Sensory adaptation is a reduction in sensitivity to a stimulus after constant exposure to it. While sensory adaptation reduces our awareness of a constant stimulus, it helps free up our attention and resources to attend to other stimuli in the environment around us.

What is the function of the sensory system?

The main function of the sensory nervous system is to inform the central nervous system about stimuli impinging on us from the outside or within us. By doing so, it informs us about any changes in the internal and external environment.

How did the development of Cephalization benefit the vertebrates?

Advantages in Cephalization Animals

The brain serves as a command and control centre for organising and controlling sensory information. Animals can evolve complex neural systems and higher intelligence over time. The second benefit of cephalization is that sense organs can be concentrated in the front of the body.

What is Cephalisation how it useful to its possessors?

It is useful to its possessors as it helps in the quick voluntary movements to either find prey, or avoid being a prey. It also allows for the organism to have an axis of symmetry, further making quick movements possible as the organism can either find prey or avoid being prey.

What are the advantages of cephalization and bilateral symmetry?

The combination of cephalization and bilateral symmetry allowed for the development of a digestive system consisting of a mouth at one end and an anus at the other. This combination of features allows the organism not only to be smart, but also to move in complex ways.

What are the main advantages of bilateral symmetry?

The advantages of bilateral symmetry include the formation of a head and tail region, where the head region can house a detailed nervous system, and more directional movement to include the ability to move straight forward.

What is cephalization in simple words?

Definition of cephalization

: a tendency in the evolution of organisms to concentrate the sensory and neural organs in an anterior head.

Does the Hydra show an advanced degree of cephalization?

Cephalization in the Animal Kingdom

Even hydras, which are primitive, radially symmetrical cnidarians , show some degree of cephalization. ... They also have a fairly advanced degree of cephalization, with sense organs (photosensory and chemosensory cells) and a brain concentrated at the anterior end.

What is the special term for the development of a head region?

The development of a head region, called cephalization, evolved at the same time as bilateral symmetry in animals. Some species of flatworms are free-living organisms that feed on small organisms and rotting matter. There are over 11,000 species of parasitic flatworms that live in the intestines of their hosts.
