This means it generates its own rhythmic action potential independent of the nervous system. • sinoatrial node- is the impulse-generating (pacemaker) tissue located in the right atrium of the heart‚ and thus the generator of normal sinus rhythm. • pacemaker cells- are specialized cells that cause involuntary muscles and tissues to

Nancy Yedanapalli physio ex Activity 6 1. Explain why the larger waves seen on the oscilloscope represent ventricular contraction. a. The ventricular contraction is of greater force than the atrial contraction‚ since the ventricular contraction functions to send blood throughout the entire body (systemic circulation)‚ where as the contraction of the atrium send blood only to the lungs and rest of the the heart (pulmonary circulation). 2. Explain why the amplitude

The electrical activity of the heart: the electrocardiogram Electrical activity is a basic characteristic of the heart and is the stimulus for cardiac contraction. Disturbances of electrical function are common in heart disease. Their registration as an electrocardiogram (ECG) plays an essential role in the diagnosis and management of heart disorders. THE GENESIS OF THE ELECTROCARDIOGRAM Pathways of conduction and the electrocardiogram The sinus node is situated in the right atrium

Light and nutrients. Light is the key abiotic factor which controls the growth of woodland. It controls the spacing of the trees‚ shape of the trees and the shape and structure of the shrub and ground layers. If a trees branch does not receive enough light it will die.
