Why do you have complex nerve systems?

This complex system is the command center for your body. It regulates your body's systems and allows you to experience your environment. A vast network of nerves sends electrical signals to and from other cells, glands, and muscles all over your body. These nerves receive information from the world around you.

What is a complex nervous system?

Central nervous system

The nervous system is the most complex and highly organized body system. It receives information from the sensory organs via nerves, transmits the information through the spinal cord, and processes it in the brain.

Do humans have a complex nervous system?

Evolution of the Nervous System

Many scientists and thinkers (Cajal, 1937; Crick & Koch, 1990; Edelman, 2004) believe that the human nervous system is the most complex machine known to man. Its complexity points to one undeniable fact—that it has evolved slowly over time from simpler forms.

Who has the most complex nervous system?

Mammals have the most complex nervous system on the planet, with humans being the most advanced. The nervous system works with the senses to transmit information to the mammal's brain, a process that takes less than one-hundredth of a second.

Do all living things have complex nervous systems?

All animals have a true nervous system except sea sponges. ... The insect nervous system is more complex but also fairly decentralized, with a brain, ventral nerve cord, and ganglia (clusters of connected neurons). These ganglia can control movements and behaviors without input from the brain.

How do you know if your nervous system is damaged?

Signs and symptoms of nervous system disorders

Persistent or sudden onset of a headache. A headache that changes or is different. Loss of feeling or tingling. Weakness or loss of muscle strength.

What is the most complex system of the human body that regulates the other system?

The nervous system is the control center of the human body. It is made up of the brain, spinal cord, and nerves. It receives and interprets stimuli and transmits impulses to organs.

What is the most complex part of human body?

The human brain is a 3-pound (1.4-kilogram) mass of jelly-like fats and tissues—yet it's the most complex of all known living structures.

How the nervous system works and its complex role in the body?

Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body. These electrical signals travel between your brain, skin, organs, glands and muscles. The messages help you move your limbs and feel sensations, such as pain.

How does a mammals nervous system work?

In mammals, the spinal cord contains a series of segmental ganglia, each giving rise to motor and sensory nerves that innervate a portion of the body surface and underlying musculature. On the limbs, the layout of the innervation pattern is complex, but on the trunk it gives rise to a series of narrow bands.

Do trees feel pain cutting?

Unlike us and other animals, plants do not have nociceptors, the specific types of receptors that are programmed to respond to pain. They also, of course, don't have brains, so they lack the machinery necessary to turn those stimuli into an actual experience. This is why plants are incapable of feeling pain.

What is the purpose of the nervous system?

The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.

What is the purpose of nervous system in animal body?

The nervous system coordinates the more rapid activities of animal life, such as movement, while the hormones integrate everything else.
