Where is the alpha located in the body?

In the body, the term "alpha" can refer to different contexts, but commonly it relates to alpha receptors in the autonomic nervous system, primarily located in the blood vessels and smooth muscles. Additionally, in the context of brain function, alpha waves, associated with relaxed alertness, are measured using an electroencephalogram (EEG) and are primarily found in the occipital and parietal lobes. If you're referring to something specific like alpha particles or alpha males, please clarify for a more precise answer.
