Applied Pathophysiology for the Advanced Practice Nurse QUESTION AND ANSWERS
MITOSIS VS MEOSIS - (ANSWER)MITOSIS= SOMATIC CELLS
MEOSIS= SEX OR GAMETE CELLS
WHAT IS IMPORTANT IN MAINTAINING CELLULAR HOMEOSTASIS? -
(ANSWER)CELLULAR COMMINICATION
THREE WAYS IN WHICH CELLS SIGNAL TO EACH OTHER IN ORDER TO
COORDINATE MOVEMENTS OR PROCESSES? - (ANSWER)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 - (ANSWER)
CELL DEATH (PROGRAMMED CELL DEATH)
APOPTOSIS - (ANSWER)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 - (ANSWER)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 - (ANSWER)
CELLULAR DEATH OCCURS BY
Apoptosis & Necrosis - (ANSWER)they both be blebbing along plasma membrane
Epithelial tissue - (ANSWER)lines the internal organs and exterior surfaces of the body, ex: skin,
innermost lining of blood vessels, & LIVER.
function is dependent on location
Epithelial Cells ALL HAVE..
4 - (ANSWER)1. offer a protective barrier for other tissue
2. perform secretion and excretion
3. absorb chemicals and nutrients
4. filter substances
Epithelial Cell Information - (ANSWER)1. plays a role in sensory perception
2. die and reproduce quickly
3. maintain a high constant density of Epithelial tissue
Muscle tissue functions - (ANSWER)involuntary & voluntary movements --> directed by the
nervous system
