Feedback Mechanism Of Adrenaline On The Cardiovascular System
The vascular system performs circulation of blood throughout the body. It consists of the arteries and veins that run everywhere including the head, neck, chest, abdomen and all 4 extremities. The heart might also be included as it is the pump that circulates the blood thru the vascular system. The lymphatics of the body are also considered a third part ...Read more
What are two ways the endocrine system directly impacts the functions of the cardiovascular system?
Many...: Via adrenaline it puts more stress on the heart, making it beat harder, stronger and faster. Nor-adrenaline causes the blood vessels to contract, raising the blood pressure. High Insulin levels, as in "pre-diabetes" cause the release of free fatty acids which damages the blood vessel walls, causing plaque formation. Cortisol and other hormones also have adverse effects. ...Read moreSee 1 more doctor answer
ConstrucT : Anabolism and catabolism both continue emergency arise so sympathetic or flight fight comes in action emergency over reconstruction begins parasympathetic takes over again which is our base line. ...Read more
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
Yes: The body works as a very efficient system where one complements the other and when one is out it has to be repaired for it to work in harmony. ...Read more
Please clarify: Frankly, I have no idea what your post means. The vagus nerve is PART of the nervous system. It's part of the parasympathetic nervous system. Maybe if you posted what led you to ask the question I could figure out what you mean because right now I haven't got a clue. It's like asking, "Which part of the car is control by 75% of the windshield?" ...Read more
Intricate connection: The respiratory system provides oxygen that nourishes the entire body, including the heart and vascular system. Without oxygen, we die. Without the left heart, oxygenated blood cannot be pumped through the body. De-oxygenated blood also has to get back to the lungs to be re-oxygenated. Receiving this blood from the vena cava, the right heart pumps it back through the lungs. ...Read more
Is heart rate a part of the autonomic system? Do antipsychotics raise heart rate? Do antipsychotics damage autonomic system thereby raising heart rate

Why do the cholinergic agonist drugs act on the parasympathetic (but not the sympathetic) nervous system?
CNS depressant: I don't know that anyone has an absolute lock-down on this mechanism, but you can look up what's known in goodman and gilman's pharmacologic basis of therapeutics. Gaba-a receptors are inhibitory in the brain, and their function can be enhanced by alcohol as well as sedative-hypnotic agents including benzodiazepines. Several types of ion channels in the brain are sensitive to ethanol also. ...Read moreSee 1 more doctor answer
If the immune system mediated an aggressive attack on the whole peripheral nervous system and killed the entire nerves of the body what are symptoms ?
Death: Although i just answered your question, important to understand that this would involve a rare progressive irreversible anaphylactic allergic reaction, and this really affects numerous organ systems. However, consider that there are chronic immune disorders that attack peripheral nerves (cidp), and nerves in central brain and spinal cord (ms). This is almost never an all or none situation. ...Read more

If the immune system mediated an aggressive attack on the whole peripheral nervous system and killed the entire nerves of the body are you paralyzed?
Wrong: Hi. The adrenal gland has two district functional components: the cortex which makes steroid hormones and the medulla which secretes the "neurotransmitters" (but hormones in this context) epinephrine, norepinephrine, and dopamine. The adrenal medulla IS part of the nervous system, and is the equivalent of a presynaptic neuron; release is to blood instead of a postsynaptic nerve or muscle cell. ...Read more
How does one take care of their autonomic nervous sytem. How about taking care of the parasympathetic sympathetic and central nervous system?
Intriguing question: Control of the autonomic nervous system (sympathetic and parasympathetic) probably best attained by studying biofeedback, autogenic training, and meditation. A web-based program at heartmath.Com is recommended. Otherwise, an ascetic isolated decade-long yogi sojurn in an himalayan cave can be undertaken. The idea is to train the unconscious mind to be obedient. Avoid anger and fear. Seek love. ...Read more
