Do insects have pain nerves?

No. There are many types of insects, and the ones we have seen so far are painless and do not feel pain. Its response is mostly instinctive, and it is regulated by hormones.

And many insect species have a self-cutting function, when it encounters danger, it will instinctively tighten the muscles, can cut off the legs or other parts, in order to save life. Therefore it is painless, that is, it does not have pain nerves.

Some. But it is basically only distributed in two places, one is the antennae distributed in the antennae (so the attack here can see extremely strong resistance), and the second is the inside of the mouthparts (so spicy is actually pain, and some spicy things can also prevent insects).

The rest of the body only reacts to stress, not pain.

The nervous system of insects, with the exception of the brain, is mainly composed of a series of ganglia of the ventral nerve cord. Therefore, insects are similar to annelids in that they are ventral nerve cords. The nervous system of insects is composed of three parts: the central nervous system, the sympathetic nervous system and the peripheral nervous system.

The central nervous system is the control center of insect nerve impulses and endocrine; The sympathetic nervous system mainly includes the oral tract sympathetic nerve that controls the digestive tract and the middle nerve that controls the valve and dorsal blood vessels. The peripheral nervous system is a neural network composed of nerve fibers of sensory and motor neurons, mainly distributed on the body surface of mollusc larvae.

1. Pain is the feeling that the organism is injured and devastated **. Nociception is a response from the central nervous system to electrical signals sent by the peripheral nervous system, which is responsible for transmitting electrical signals. Therefore, no peripheral organ can produce pain alone.

Problems in any of the peripheral nervous system, from the electrical signals generated by the peripheral nervous system to the pathways that transmit the pathways to the central cells that process pain, can lead to a partial or total loss of pain sensation. Pain perception is an important protective mechanism for humans.

Second, invertebrates that have somites in insects have ganglia (so it cannot be said that there is no nerve center), and they can all perceive the outside world. But there seems to be little controversy about the fact that they do not have pain nerves;

The question is, is it certain that if there are no pain nerves, they can be judged that they do not feel pain? Pain is a subjective feeling of human beings, and perhaps lower beings themselves will also feel uncomfortable, but it does not depend on the pain nerves and pain transmission mechanisms of higher beings. After their limbs are severed, they will also curl up and struggle (and such struggles have no direct effect on the pursuit of advantages and disadvantages, but are similar to the behavior of higher animals when they are in pain, muscle contractions, screaming and even rolling on the ground), although they do not have pain nerves, but they still have the bad feeling of pain.

So far, the insects I have seen are probably not painful, and as for people who feel that they have pain, it is also because people can subjectively feel pain, so they impose their own feelings on insects, which is some of my own understanding.

The first one is to go back to my grandmother's house in the summer, because my grandmother's house is on the outskirts of the city, although it is also a building, but there are many mosquitoes and flies in the summer. Every time I go to my grandmother, I ask me to shoot flies, and my sense of this person is not very accurate, so I can rarely hit flies.

I hit the fly again, and I could clearly see the internal structure of the fly, but the fly did not die, and even flew out of the window very arrogantly. From this, it can be judged that as long as the fly's wings are still there, it can fly, and as for the pain of intestinal piercing, it is nothing, or it does not feel it at all.

Another time my brother and I went to cut leeks, there was a beetle to my brother frightened, my brother immediately gave the insect a knife, almost cut off the waist, when my brother and I cut the leek, saw that the insect is still slowly crawling forward, which also shows that as long as the insect still has a breath will survive tenaciously, so the feeling of pain is nothing for insects.

Although insects are also a kind of creatures, their senses are different from people, some people feel that insects will be painful, that is because they impose their sensory behavior on insects, so insects are painful in their eyes, but whether it is flying or reptilian insects, they can't feel general pain.

I am a cute flower beetle, and I am very happy to play in the flowers every day. One day my companion told me if I wanted to go to a human house to eat something delicious, but I didn't want to go, I was afraid that humans would break my beautiful wings. But my companion told me that it was okay, as long as we flew fast enough, humans would not do anything to us.

So I was moved, simply packed my luggage, and went with my companions.

I especially want to give that bear child a lesson in biology, we insects are the same as you humans, we have pain nerves, how can we not feel pain? He also said that you humans are high-IQ animals, and we don't even know whether our insects feel pain, and it's really IQ that makes us insects worry. Can't your big eyes see that we're dying?

Our wings are shaking violently, our antennae are starting to grow in frequency, and we are squeaking. We have to shout human language, Lao Tzu is very painful, will we understand whether we insects feel pain?

My companion and I fled in the dead of night and swore that we would never come to the human home. It's really a toss-up, stupid humans still have this kind of thought, they don't even see us as insects, although we are insects, but we are also very complete, okay.

I'm sorry to tell you: no! Everything about insects is based on instinctive reactions, regulated by hormones.

Then why does it react so violently when you break its leg? Actually, it's easy to explain, like you don't know it hurts, but when you see someone sawing your leg, you're instinctively scared, that's all. Moreover, many insects have a self-cutting function, and when they encounter danger, they will instinctively tighten their muscles and break their legs.

So, insects don't actually feel pain, not even pain nerves.

Our ancestors were originally single-celled, then invertebrates, then fish, reptiles, mammals, became biological humans, and all other humans became extinct, leaving only Homo sapiens now... So how do you set this dividing line?

I just couldn't stand the noise of the crabs being cooked, it felt like murder, but I ate them anyway because I love crabs. But because of the way the crabs are cooked alive, I told my family that I don't eat crabs anymore. It's not pretentious, it's just that I'm suffering from the crab's struggle, I'm crying, maybe the little girl is too weak, and the compassion is strong, but in order not to be sad, don't eat if you don't eat, anyway, I can eat something else...

Crabs are invertebrates like insects, I have killed insects when I grew up, because I have been afraid of insects since I was a child, ** and reality do not dare to look, disgusting from the heart, no matter what you say to scare me or have a grudge against me, as long as I don't think of seeing them**, as long as I can remove my eyes from insects, or let them disappear from my eyes, we can be good friends, it's so serious, even if I sleep on the street, I just can't look at insects. It wasn't until I became an adult that I decided to bravely close my eyes and kill them, because I was born wrong, as soon as I heard scientists say that the extinction of mosquitoes has no big impact on the ecology, I wished they would disappear, what sympathy I didn't have for insects at all, because my subconscious fear and hatred made me feel that insects are so ugly and so terrible, how can they have consciousness and thoughts. It seems that there is no harmony between natural mortal enemies.

Now, like many people in China, I don't think about the feelings and power of animals, because ignorance is really happy and good. Women are born lowly, this idea made the ancients very harmonious, left-handers are demons, this idea made the ancients happy, homosexuals are crazy, this idea made the ancients happy. Ignorance is bliss.

However, I usually take the vegetarian route, because red meat is too toxic, and there are a bunch of substitutes for the nutrition of food with legs, only fish occasionally thinks of omega-3 before eating, and I have a bottle of omega-3 fish oil at home and have never eaten it, I mainly eat egg, milk and vegetarian food. Toast, salad dressing, lettuce, pepper, salt, and especially cheese in salads are my favorites, and I am determined to research 10,000 ways to make salads... Life is also quite pleasant.

Hope this helps as to the reason why this issue was raised. Is it ignorance and happiness, or is wisdom bound to hurt? The actual number of people has already given the answer, and since people like you have asked, I am afraid that they are not willing to live an ignorant and happy life, so that they can do their own thing.

There isn't enough evidence to prove that these animals have pain nerves, but this raises another question. The question of whether many animals, such as mollusks, such as insects, are able to feel pain may be difficult to determine for a long time. Molluscs also keep their shells tightly closed, but Peter Singer doesn't think they feel pain.

So can we stay with pearls? Can you eat oysters? Can you wear silk?

Can you eat honey? What are we going to draw a line in? I've heard that some people draw the line by whether they have eyes, some people draw the line by whether they will escape, and some people draw the line by vertebrates.

When we asked Tom Regan, the originator of animal rights, he replied, "You don't need to know everything to know part of it." For example, I don't know exactly how tall a person has to be to be tall or how old they have to be to be old, but I do know basketball star O'Neal Shako'Neal is tall, while Grandma Moses is old.

Similarly, I don't think we have to know that we should draw the line in **...My view has always been that we should assume that such animals have feelings when we are unsure. While we're not sure if they should have rights, we don't need to eat them to live; So why eat them?

My personal opinion is that everyone can draw a line where they feel comfortable with these animals. The key is that we have accurate information and try to be conservative when we are unsure. That means try not to hurt them when you don't have to, even if we're not sure if they're in pain.

Lower animals or insects are pain-aware because they have a complete reflex arc just like humans, that is, the receptive system, the conduction system, and the nerve center (and half of the reflex arc responds to pain).

And I think there is, creatures have the ability to dodge damage, just like if you put salt on the end of an earthworm, it will crawl in the opposite direction to dodge, and life forms are all good and bad things.
