Final answer:
The nervous system is a complex network of tissues that uses chemical and signals to carry messages between the brain and the rest of the body. It includes the brain, spinal cord, and a network of nerves that run throughout the body. Another system that should be activated by these chemical messengers is the endocrine system. The nervous system and the endocrine system work together to maintain dynamic homeostasis by timing and coordinating regulated events.
Step-by-step explanation:
The nervous system is a complex network of tissues that uses chemical and signals to carry messages between the brain and the rest of the body. It includes the brain, spinal cord, and a network of nerves that run throughout the body. The main function of the nervous system is to coordinate and control body functions and respond to changes in the environment.
The nervous system works by sending and receiving electrical signals through nerve cells called neurons. These signals travel from one neuron to another, allowing the communication between different parts of the body. For example, when you touch a hot stove, the sensory neurons in your hand send a signal to the brain, which then sends a signal to your muscles to quickly pull your hand away from the stove.
Another system that should be activated by these chemical messengers is the endocrine system. The endocrine system consists of glands that produce and secrete hormones into the bloodstream. These hormones travel throughout the body and regulate various functions, such as metabolism, growth, and reproduction. The nervous system and the endocrine system work together to maintain dynamic homeostasis by timing and coordinating regulated events.
