dura mater - Outer layer of meninges, tough, fibrous, double layered.



dural sinuses - Formed by spits in dura mater. Collect venous blood and CSF for return to general
circulation.



mediastinum (what is it) - Area of thoracic cavity between lungs. Location of trachea, esophagus, heart
& large vessels



pericardial sac - Fibrous sac, holds heart, double-walled, anchors heart to diaphragm.



endocardium - inner layer of heart, forms 4 heart valves



septum in heart - separtes L & R sides of heart



SA node - other name - pacemaker



sinus rhythm - basic rate of impulses generated by SA node (70 beats per minute)



location of sinoatrial node - right atrium



Where does impulse go to after SA node - Spreads through atrial conduction pathways, resulting in
contraction of both atria



AV node - what is it - Atrioventricular node. Impulse arrives here after SA node sent it through atria



AV node - where is it - Floor of R atrium near septum. Is the only anatomical connection between atrial
and ventricular portions of conduction system.

,AV bundle - other name - Bundle of His - other name



ECG - what does it do - Records electrical changes sent by conduction impulses as picked up by
electrodes



apoptosis - normal programmed cell death in tissues

great reserve capacity of some organs. Ex: kidney damage may progress to an advanced stage of renal
failure before symptoms are manifested.



latent - silent stage, no clinical signs evident. May be called incubation period in some infectious
diseases. May be communicable during this period.



prodromal - time in early development of disease; pt know of change in body, but signs are nonspecific;
a stage in infections. Labs tests are negative, difficult to confirm diagnosis.



manifestations - clinical evidence or effects, signs and symptoms, local or systemic



lesion - specific local change in tissue, may be microscopic



syndrome - collection of signs and symptoms, often affecting more than one organ. Usually occur
together in response to a certain condition.



remission - manifestations of the disease subside



exacerbation - manifestations of the disease increase



precipitating factor - condition that triggers an acute episode. Ex - shoveling snow on a cold day may
