In the palate, this dilation is sensed by nearby pain receptors, which then send signals back to the brain via the trigeminal nerve, one of the major nerves of the facial area. This nerve also senses facial pain, so as the neural signals are conducted the brain interprets the pain as coming from the forehead—the same " referred pain ...
The cold water can cause heart attack due to severe vasoconstriction, [2] where the heart has to work harder to pump the same volume of blood throughout the arteries. For people with pre-existing cardiovascular disease, the additional workload can result in myocardial infarction and/or acute heart failure, which ultimately may lead to a cardiac ...
So, why the heck do we. Brain freeze is so serious it has a scientific name: sphenopalatine ganglioneuralgia. You drink or eat something cold very fast and BOOM, your head feels like someone's ...
As a result, the heart has a hard time pumping blood through the lungs, and the blood vessels eventually undergoes fibrosis. The increased workload on the heart causes hypertrophy of the right ventricle, which leads less blood being pump through the lungs and decreased blood to the left side of the heart. As a result of all of this, the left ...
AFib, atrial flutter, heart attack, heart valve disease, obesity, obstructive sleep apnea, high blood pressure, smoking and type 2 diabetes are just a few of them. Heart failure results in less ...
The cardiovascular centre affects changes to the heart rate by sending a nerve impulse to the cardiac pacemaker via two sets of nerves: sympathetic fibres, part of the autonomic nervous system, to make heart rate faster. the vagus nerve, part of the parasympathetic branch of the autonomic nervous system, to lower heart rate.

The dural sinuses are therefore located on the surface of the cerebrum. The most prominent of these sinuses is the superior sagittal sinus which is located in the sagittal plane under the midline of the cerebral vault, posteriorly and inferiorly to the confluence of sinuses , where the superficial drainage joins with the sinus that primarily ...
