NUR612 Pathophysiology of the Adult
for Advanced Practice Nursing
MITOSIS VS MEOSIS - ✔MITOSIS= SOMATIC CELLS
MEOSIS= SEX OR GAMETE CELLS
WHAT IS IMPORTANT IN MAINTAINING CELLULAR HOMEOSTASIS? - ✔CELLULAR
COMMINICATION
THREE WAYS IN WHICH CELLS SIGNAL TO EACH OTHER IN ORDER TO
COORDINATE MOVEMENTS OR PROCESSES? - ✔1. DISPLAY "SIGNAL
MOLECULES" ON EXTERNAL SURFACE OF PLASMA MEMBRANE
2. SEND SPECIFIC SIGNAL MOLECULES TO OTHER CELLS THAT BIND TO
INTRACELLULAR RECEPTOR; SIGNAL TRANSMITTED DIRECTLY TO NUCLEUS
3. GENERATING PROTEIN CHANNELS ON THE PLASMA MEMBRANE THAT CAN
DIRECTLY EFFECT THE ACTIVITY OF ADJACENT CELLS
Cells undergo - ✔
CELL DEATH (PROGRAMMED CELL DEATH)
APOPTOSIS - ✔OCCURS NATURALLY OR PREMATURELY( DX )
APOPTOSIS: STARTS WITH BREAK DOWN OF CHROMATIN; CELLS BREAKDOWN
INTO DISCRETE APOPTOTIC BODIES THAT ARE ABSORBED BY PHAGOCYTES
CELLS THAT DIE AS THEY WERE PROGRAMMED IN EFFORTS TO MAKE ROOM
FOR MORE & NEW CELLS
NECROSIS OF A CELL - ✔THE CELL SWELLS AND RUPTURE APPEARS ALONG
THE PLASMA MEMBRANE (BLEBBING).
THE REMNANTS OF THE NECROTIC CELLS LEAK INTO THE TISSUE CAUSING
INFLAMMterm-4ATION
CELL DEATH (PROGRAMMED CELL DEATH)
AUTOPHAGY - ✔
CELLULAR DEATH OCCURS BY
Apoptosis & Necrosis - ✔they both be blebbing along plasma membrane
Epithelial tissue - ✔lines the internal organs and exterior surfaces of the body, ex: skin,
innermost lining of blood vessels, & LIVER.
function is dependent on location
