When pressure on the Median Nerve is removed, the symptoms go away and so does the threat of permanent nerve damage. The Median Nerve, runs right through the narrow passage known as the Carpal Tunnel at the base of the hand just beyond the wrists. The numbness and loss of feeling sensation is the bodyâs way of declaring itself injured and needing attention.
Ventricular diastole is the period during which the ventricles are filling and relaxing, while atrial diastole is the period during which the atria are relaxing. The term diastole originates from the Greek word Î´Î¹Î±ÏÏÎ¿Î»Î·, meaning dilation. Diastole is closely related to the phenomenon of recoil within ballistics.
Systole is the last stage of a heart beat. It happens right after diastole, when the heart refills with blood. During systole, the heart's two ventricles contract (squeeze). (The ventricles are the largest parts of the heart, which pump blood to the body and lungs.) During systole, the heart muscle gets an automatic electrical signal that tells the heart to contract (squeeze). This makes the blood flow out of the heart.
