Neurotransmitters are brain chemicals that transmit information throughout our brain and body. They transmit nerve signals electrically and chemically between neurons. Neurotransmitters can affect mood‚ sleep‚ concentration and weight. The two kinds of neurotransmitters are: inhibitory and excitatory which‚ respectively‚ calm and stimulate the brain. Dopamine is an inhibitory neurotransmitter so when dopamine reaches the receptor sites‚ it blocks the neuron from firing. Dopamine is produced in multiple

Neurotransmitters Dr. C. George Boeree Neurotransmitters are the chemicals which allow the transmission of signals from one neuron to the next across synapses. They are also found at the axon endings of motor neurons‚ where they stimulate the muscle fibers. And they and their close relatives are produced by some glands such as the pituitary and the adrenal glands. In this chapter‚ we will review some of the most significant neurotransmitters.

Homeostatic Imbalances Homeostasis is the maintenance of relatively stable conditions within the body. This process‚ controlled through feedback systems‚ ensures that the body’s internal environment remains stable despite changes in the external environment. Feedback systems are composed of a receptor‚ a control center‚ and an effector. When one or more of the components do not function properly the body is placed in a state of homeostatic imbalance. This condition can range in severity‚ but
