M. H. (hormone research)

M. H. can refer to "melanocyte-stimulating hormone," which is a hormone produced by the pituitary gland. It's primarily involved in regulating skin pigmentation by stimulating melanocytes, the cells responsible for producing the pigment melanin. This hormone can influence skin color changes, such as tanning or protective responses to UV exposure. Additionally, it plays a role in appetite regulation and energy balance. Overall, M. H. affects not only appearance but also some metabolic processes in the body. Understanding its function helps clarify how hormones influence various bodily processes and responses.
