Hormones are the secondary messengers that are transferred across the body system to regulate body functions. The systems which regulate the secretion of hormones are the nervous system and endocrine system. The coordinated functions of these systems help in maintaining a proper level of hormones....
Hormones are molecules released by a group of cells in the body that influence the behavior of another group of cells. Hormones are the chemical signals of the endocrine system, the group of glands that, along with the nervous system, controls the body's responses to internal and external ...
Hormones Balance. I’m here today with Dr. Alan Hopkins. I’m super excited to be able to bring to you a way to order labs, urine as well as blood on your own without having to negotiate, argue, and beg a doctor for ordering these labs which so many of you are asking us every ...
Sex hormones impact a number of aspects of immunity. As a result of the aging process, dramatic changes occur in the endocrine system, including the levels of sex hormones. Thus, it is possible that the hormonal environment may play a role in the effects
Endorphins, dopamine, serotonin, and oxytocin are neurotransmitters, or chemical messengers released by neurons that target different parts of the body. They work, at times together, to facilitate a communication loop between the nervous system and brain, Wyatt explains. This internal conversation of ...
