Webb8 nov. 2024 · In addition, humans have a centralized nervous system consisting of the brain, spinal cord, and nerves. On the other hand, insects have a decentralized nervous system composed of the brain, ganglia, and nerves. Below, we will dive into the anatomy and functioning of an insect’s pain receptors.
WebbCorals Scientific Name: Anthozoa Corals do not have a brain, but they do have a nervous system known as a nerve net. This system extends from the animal’s mouth down to its tentacles. There are an average of 6,000 species of corals, and they come in various colors, sizes, and shapes. Insects have a complex nervous system which incorporates a variety of internal physiological information as well as external sensory information. As in the case of vertebrates, the basic component is the neuron or nerve cell. This is made up of a dendrite with two projections that receive stimuli and an axon, which transmits information to another neuron or organ, like a muscle. As with vertebrates, chemicals (neurotransmitters such as acetylcholine and dopamine) are releas…
