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 heart's electrical system. The heart is, in the simplest terms, a pump made up of muscle tissue. Like all muscle, the heart requires a source of energy and oxygen in order to function.The heart's pumping action is regulated by an electrical conduction system that coordinates the contraction of the various chambers of the heart.ike all muscle, the heart requires a source of energy and oxygen in order to function.
