What else can I help you with?
Do all animals have complex nervous systems?
Not all animals have complex nervous systems. In fact, most lower animals don't even show an organized nervous system. Its only in higher animals like chordates that a proper organized nervous system is seen.
Do all animals other than man have self consciousness?
No. There are animals without any nervous systems, like sponges.
Why are chordates considered to be the highest and the most advanced group of animals?
Because of their complex organs, circularitory systems, nervous systems, and gas exchange systems.
Is the nervous system an organ system?
Yes, the nervous system is considered one of the organ systems in animals.
Do lobsters have nervous systems and how do they function in comparison to other animals?
Yes, lobsters have nervous systems that are similar to other animals. Their nervous systems help them sense their environment, move, and respond to stimuli. Lobsters have a decentralized nervous system, meaning that they have clusters of nerve cells called ganglia throughout their bodies, rather than a centralized brain like mammals. This allows them to react quickly to stimuli and control their movements efficiently.
Is it true that all animals without specialized nervous systems tend to be very small and very mobile.?
While many animals without specialized nervous systems, such as certain invertebrates, tend to be small and mobile, this is not universally true. Some larger organisms, like jellyfish and sponges, also lack complex nervous systems but can exhibit various forms of movement or remain largely stationary. The size and mobility of these animals are influenced by their ecological niches and evolutionary adaptations rather than solely by the absence of a specialized nervous system.
Do fruit have a brain?
No, plants do not have brains. Only vertebrate animals have brains, although invertebrate animals do have a comparable organ that controls their nervous systems.
What are the two nervous systems?
parasympathetic and sympathetic nervous systems
Do paramecium feel pain?
No, paramecium do not have a nervous system or pain receptors, so they do not experience pain like animals with more complex nervous systems. They respond to stimuli in their environment to survive and reproduce.
Do amoeba have nervous systems?
Yes, they do have a nervous system.
The peripheral nervous system is made up of the autonomic systems and what other system?
The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous systems.
What are the two kinds of nervous systems?
The two kinds of nervous systems are sympathetic and parasympathetic. P.S. The two parts of the nervous system are Central and Peripheral.
