LATEST PATHOPHYSIOLOGY TEST 2025-2026 EXAM
QUESTIONS AND CORRECT DETAILED ANSWRS VERIFIED BY
EXPERTS ALREADY GRADED A+
dura mater
ANSWER;Outer layer of meninges, tough, fibrous, double
layered.
dural sinuses
ANSWER;Formed by spits in dura mater. Collect venous blood
and CSF for return to general circulation.
mediastinum (what is it)
ANSWER;Area of thoracic cavity between lungs. Location of
trachea, esophagus, heart & large vessels
pericardial sac
,ANSWER;Fibrous sac, holds heart, double-walled, anchors heart
to diaphragm.
endocardium
ANSWER;inner layer of heart, forms 4 heart valves
septum in heart
ANSWER;separtes L & R sides of heart
SA node - other name
ANSWER;pacemaker
sinus rhythm
ANSWER;basic rate of impulses generated by SA node (70 beats
per minute)
,location of sinoatrial node
ANSWER;right atrium
Where does impulse go to after SA node
ANSWER;Spreads through atrial conduction pathways, resulting
in contraction of both atria
AV node - what is it
ANSWER;Atrioventricular node. Impulse arrives here after SA
node sent it through atria
AV node - where is it
ANSWER;Floor of R atrium near septum. Is the only anatomical
connection between atrial and ventricular portions of
conduction system.
, AV bundle - other name
ANSWER;Bundle of His - other name
ECG - what does it do
ANSWER;Records electrical changes sent by conduction
impulses as picked up by electrodes
apoptosis
ANSWER;normal programmed cell death in tissues
endogenous
ANSWER;originating from within the body
exogenous
ANSWER;originating from outside the body
