What is the neural system of all animals composed of?

Step-by-step solution

Coordination refers to the process by which two or more organs interact and complement each other's functions in order to maintain homeostasis. The neural system of all animals is composed of highly specialized cells called neurons, which can detect, receive, and transmit different kinds of stimuli. The neural organization is very simple in lower invertebrates such as Hydra, and is composed of a network of neurons. The neural system is better organized in insects, where a brain is present along with a number of gan
