Why are echinoderms animals?
Echinoderms, such as starfish, have basal nerve ganglia that serve as a nervous system. They also have a water vascular system that acts as a circulatory system. They can reproduce, move, and digest food. Therefore, they are animals.
Identify and describe the unique system an echinoderm has what is it used for?
The name echinoderm means "spiny skin." Echinoderms have spines of various lengths that cover the outside of their bodies. Most echinoderms are supported and protected by an internal skeleton made up of bonelike plates. Echinoderms have a simple nervous system but don't have heads or brains.
Which group of invertebrates have a water vascular system and tube feet?
Echinodermates possess a water vascular system.
What is the body system for spines in Echinoderms?
water vascular system
How are cephalopod nervous systems unique among mollusks?
Well what I know about this question is that..............Cephalopods nervous system is like this all echinoderms have a simple nervous system similar to that of a jellyfish. Around the mouth is a circle of nerve fibers called the nerve ring. In sea stars, a radial nerveruns from the nerve ring to the tip of each arm.The radial nerves control the movements of the sea star's arms.One characteristic that is unique to echinoderms is the water vascular system. The water vascular system is a system of canals filled with fluid. It uses water pumps to help the animal move, eat, breathe, and sense its environment.The water vascular system of a sea star. Notice how water pressure from the system is used for many functions.
Do echinoderms have a water vasculartory system?
yes they do
What organ system does the brain belong too?
The brain belongs to the nervous system. It is the primary organ responsible for processing thoughts, emotions, and coordinating bodily functions.
Does the central nervous system consist of the somatic nervous system?
No, the central nervous system consists of the brain and spinal cord. The somatic nervous system is a division of the peripheral nervous system that controls voluntary movements and receives sensory information.
What comprises the nervous system?
The Sympathetic Nervous System and the Parasympathetic Nervous System
The portion of the nervous system away from the central nervous system?
The peripheral nervous system is the portion of the nervous system away from the central nervous system. It consists of nerves that connect the central nervous system to the rest of the body, including sensory and motor neurons. The peripheral nervous system is responsible for transmitting information to and from the central nervous system.
