In clinical practice, we might scrape the arch of your foot with the handle of a reflex hammer. Plantar flexion of the great toe is normal. Dorsiflexion (pointing of the toe upward) is not. But I don't know what the stimulus is in your case.
Picture of congestive heart failure. The heart is a pump that works together with the lungs. The heart pumps blood from the veins through the lungs where oxygen is added and then moves it on to the arteries. This pumping action creates a relatively high pressure in the arteries and a low pressure in the veins.
The damaged muscle either can't relax properly to let the pumping chambers of the heart -- the ventricles -- fill with enough blood, or it can't contract properly to let the ventricles pump out enough blood. The left ventricle is the main pumping chamber, and heart failure usually starts on the left side.he damaged muscle either can't relax properly to let the pumping chambers of the heart -- the ventricles -- fill with enough blood, or it can't contract properly to let the ventricles pump out enough blood.
