Is the nervous system different in different animals?

The artifact systems should all be the same, they're all nerve cells, so I don't think there's a difference.

It can only be said that the distribution is different, which can be divided into mammals, oviparity, viviparity, aquatic and other combinations, and different classifications.

The location of the distribution of the nervous system and the physiological condition of different animals are different.

Summary. Hello dear <>

Animals with a nervous system are known as vertebrates. The nervous system begins to appear in coelenterates. Nerve cells are connected to each other by neurites to form a network, and there is only one neural network in the ectoderm, so it is called the reticular nervous system.

In middle school, it is believed that all organisms with spine have a nervous system.

There is a nervous system of what animals are called.

Hello to the early Lu Qin<>

Animals with nervous systems are called vertebrates by the land orange. The Woodrise nervous system begins to appear in coelenterates. Nerve cells are connected to each other by neurites to form a network, and there is only one neural network in the ectoderm, so it is called the reticular nervous system.

In middle school, it is believed that all organisms with spine have a nervous system.

Animals with nervous systems are called higher animals. Primitive single-celled animals did not have any neurological system, and slightly higher coelenterates only had simple nerve cells, and only began to have a nervous system when they were directly searched for and lost to more advanced linear animals. The nervous system is the system that plays a leading role in regulating the physiological functions and activities of the human body. Lift up.

The primitive species of nervous system had no ganglionic differentiation, except for the peripharyngeal nerve ring and a pair of pedal cords and a pair of lateral cords extending posteriorly to the body. The higher species mainly have 4 pairs of ganglia, and each ganglion is connected by nerves. The cerebral ganglion is located on the dorsal side of the esophagus, sending out nerves to the head and front of the body, and is sensory; The pedal ganglion is located in the anterior part of the foot, extending the nerve to the foot and is responsible for motor and sensation; The lateral ganglion sends out nerves to the mantle and gills; The visceral ganglion sends out nerves to various internal organs.

These ganglia tend to be concentrated, and some species of major ganglia are concentrated together to form the brain, surrounded by cartilage, such as cephalopods. Molluscs have differentiated sensory organs such as antennae, eyes, olfactory apparatus and balance sac, and are sensitive to sense.

There are 10 pairs of cranial nerves in round mouths, fishes, and frogs, which are olfactory nerve, optic nerve, oculomotor nerve, trochlear nerve, trigeminal nerve, abducens nerve, facial nerve, auditory nerve, glossopharyngeal nerve, and vagus nerve.

Reptiles, birds, and mammals have 12 pairs of cranial nerves, which are accessory nerves and hypoglossal nerves.

Ichthyidae, amphibian 10

Crawling, Ornithischia, Mammals 12

Hello dear, the most essential difference between humans and animals in the neuromodulation square bench is that a animals have both conditioned and unconditioned reflexes, and humans only have conditioned reflexes b humans have a high-level nerve center, and animals only have a low-level nerve center c the human cavity judgment shed has another type of conditioned reflex established through the language center, while animals do not have d The conditioned reflexes formed by animals are permanent, and the conditioned reflexes formed by humans are temporary. I wish you a happy life, and I hope you can give a thumbs up and thank you!
