Maryville NURS 611 Patho Exam 1

Apoptosis - ANS A programmed cell death that is regulated or programmed. Cellular self-destruction for
elimination or unwanted cell populations

Necrosis - ANS Rapid loss of the plasma membrane structure, organelle swelling, mitochondria
dysfunction




K
What is the #1 cause of cellular injury leading to necrosis (especially the kidney and heart) - ANS
hypoxia




C
What is the #1 cause of hypoxia? - ANS ischemia




LO
Main component of a cell - ANS nucleus

What does the nucleus contain? - ANS nucleolus

What is the nucleolus composed of? - ANS RNA, most of cellular DNA, DNA binding proteins, and
YC
histones

Why are histone important? - ANS histones bind to DNA and fold it into chromosomes (chromatin)
which is essential for cell division

What are ribosomes? - ANS RNA-protein complexes (nucleoproteins) that are synthesized in the
D

nucleolus and secreted into the cytoplasm through pores in the nuclear envelope called nuclear pore
complexes (NPCs)
U


Where can ribosomes be found? - ANS cytoplasm and rough ER

what are ribosomes chief function? - ANS provides sits for cellular protein synthesis
ST




What is the Golgi apparatus (complex)? - ANS a network of flatten, smooth membranes and vesicles
frequently located near the nucleus of the cell

What does the Golgi apparatus do? - ANS takes proteins from the ER and processes/packages them into
small membrane-bound vesicles called "secretory vesicles, and refines and directs traffic in the cell

What are lysosomes and what do they do? - ANS maintain cellular health by removal of toxic cellular
components, removal of useless organelles, termination of signal transduction, and signals cellular
adaption

, How does aging affect lysosomes? - ANS leads to progressive loss of lysosomal efficiency which
declines the regenerative capacity of organs and tissue

What functions do lysosomal components integrate? - ANS nutrient abundance, energy levels, and cell
stressors and will translate them into instructions that regulate cellular metabolism toward either
proliferation or inactivity

What is mitochondria responsible for? - ANS cellular respiration, cellular metabolism , and energy
production




K
What does the inner membrane of mitochondria contain? - ANS enzymes of the respiratory chain and
are essential to the process of oxidative phosphorylation that generates most of the cell's ATP




C
The mitochondrial matrix contains what kind of pathways (1), involve what two things (2), and
metabolizes what three things (3)? - ANS 1- metabolic
2- urea and heme synthesis




LO
3- carbs, proteins, and lipids

What can accumulate intracellularly caused by stresses form metabolic dearangements? - ANS carbs,
proteins, and lipids
YC
What is physiologic atrophy? - ANS occurs in early development. ex: thymus glad during childhood

What is pathologic atrophy? - ANS occurs as a result of decreases in workload, use, pressure, blood
supply, nutrition, and hormonal stimulation.
Ex: Shrinking of gonads in an adolescent pt in response to decreased hormonal stimulation. and an pt
immobilized in bed for a prolonged time
D

what is hypertrophy? - ANS increase in cell size
U


Example of beneficial physiologic hypertrophy? - ANS hypertrophy of myocardial cells from endurance
training
ST




example of pathologic hypertrophy - ANS cardiomegaly in a hypertensive patient

What is hyperplasia? - ANS increase in the number of cells

example of compensatory hyperplasia? - ANS regeneration of the liver

example of pathological hyperplasia - ANS endometrial tissue

example of hormonal hyperplasia - ANS enlargement of the uterus during pregnancy

What is metaplasia? - ANS replacement of the cells
