Are cell phones to the brain and the human body?

Are cell phones to the brain and the human body?

U.S. C.D.C. says...: In the last 15 years, hundreds of research studies have investigated whether health problems can be linked to cell phone use. Some of these studies have suggested the possibility that long-term, high cell phone use may be linked to certain types of brain cancer. These studies do not establish this link definitively. Scientists need to conduct more studies to learn more about this possible risk. ...Read more

What are the lymphatic system parts and its functions?

Immune sys highway!: Think of the lymphatic system as a highway for the immune system. Immune cells are transported along lymphatic vessels and stop by lymph nodes, which are meeting points where these immune cells can meet and interact. If an antigen presenting cell encounters a pathogen in the tissues, it will use the lymphatic system to carry a sample to the lymph node and find other cells that recognize it. ...Read more

can the destruction of neurons nerve cells body cause chaos in the brain and body and affect chemical and electrical signals in the body?

Sometimes Yes: This question is vague and unclear, but with that said I can acknowledge that brain and body are electrical energy systems connected by miles of nerve fibers. There is much yet to be understood about the brain, but enough is known about spinal cord and brain dysfunction to know that a significant enough insult or damage to any one area can disrupt various other system processes. ...Read more

What area of the brain has the greatest effect on visceral functions (e.g. heart rate and hormone production)?

What area of the brain has the greatest effect on visceral functions (e.g. heart rate and hormone production)?

Hormones: Please go online to Yahoo Images or something similar and look for images of the Pituitary Gland. There is usually a small comment with the images. Fell free to contact me again if there are things on the web you don't fully understand. You can of course also discuss these items with your doctor. ...Read more

Which part of the brain has/controls the serotonin and dopamine neurons in the body?

Which part of the brain has/controls the serotonin and dopamine neurons in the body?

Well-many: This is a complex question, and the answer is many. The number of receptors for both of these are throughout the brain and body and are controlled by different biochemical processes which trigger excretion, secretion, reuptake, and distribution. There are different types of serotonin and dopamine receptors throughout the systems. ...Read more

The sympathetic chain is the pathway between the body (all organs and systems in the body), and disrupting it will affect the whole, not just sweating?

The sympathetic chain is the pathway between the body (all organs and systems in the body), and disrupting it will affect the whole, not just sweating?

It depends...: It depends on what kind of damage (disruption), such as: which nerves, where in the nerves, how many nerves, the size of the nerves, etc... The signals from sympathetic nerves create effects like include pupil dilation, increased sweating, increased heart rate, and increased blood pressure. ...Read more

What specific Autoimmune diseases attack brain cells and neurons causing a dramatic effect to neurotransmitters,hormones and the function of the brain

What specific Autoimmune diseases attack brain cells and neurons causing a dramatic effect to neurotransmitters,hormones and the function of the brain

Lupus: Systemic Lupus can attack everywhere and lead to the things u asked about. Other considerations are vasculitis syndromes as there is an autoimmune attack on and in blood vessels which can affect neurons indirectly. Myasthenia Gravis also affect the neuromuscular system and affects one of the main neurotransmitter, AcetylCholine. Rheumotologist is specialist to see for autoimmune disorders ...Read more

Is there a neural pathway of oxytocin from the brain to the heart? I read that there are OT receptors in rat and human hearts.

Is there a neural pathway of oxytocin from the brain to the heart? I read that there are OT receptors in rat and human hearts.

Oxytocin & the heart: The oxytocin receptor (OXTR) has been found to be expressed in heart cells of other mammals and is thought to be involved in the development of the human heart. Oxytocin is known to be transported via the nerve cell axons. Research is still underway in this field. http://www.ncbi.nlm.nih.gov/gene/5021 , http://www.nextprot.org/db/entry/NX_P30559/expression ...Read more
