UT TYLER FNP NURS 5350 Adv Patho Exam 1 Questions AND Correct Answers
3 types of cellular receptors - ✔✔plasma membrane receptors, channel-linked
receptors, non-channel-linked receptors
3 ways cells communicate - ✔✔endocrine signaling, paracrine signaling, synaptic
signaling
5 types of necrosis - ✔✔coagulative, liquefactive, caseous, fat necrosis,
gangrenous
active mediated transport - ✔✔"active transport;" Requires the expenditure of
metabolic energy (ATP); moving UP or AGAINST a concentration gradient; the
major cellular energy currency
active potential - ✔✔a rapid change in the resting membrane potential; carries
signals and conveys info from one cell to another
active transport - ✔✔the movement of materials through a cell membrane using
energy
atrophy - ✔✔reduction (shrinking) in cell size
benign tumors - ✔✔Grow slowly
Well-defined capsule
Not invasive
Well differentiated
, Low mitotic index
Do not metastasize
carcinoma - ✔✔a malignant tumor that occurs in epithelial tissue
caseous necrosis - ✔✔degeneration and death of tissue with a cheese-like
appearance; TB
causes of atrophy - ✔✔disuse (muscle tissue), reduction in blood supply
(arteriosclerotic changes causing reduced blood supply to the brain), and
decreased hormonal stimulation (aging gonads, enlarged mammary)
cellular receptors - ✔✔protein molecules on the plasma membrane, in the
cytoplasm, or in the nucleus that can recognize and bind with specific smaller
molecules called ligands
Characteristics of plasma membrane - ✔✔made up of lipids and proteins; the
basic component is a bi-layer of lipid molecules that are responsible for the
structural integrity of the membrane
chemical injury to cells - ✔✔begins w/ a biochemical interaction between a
toxic substance and the cell's plasma membrane (which is ultimately damaged)-
->leading to increased permeability
Coagulative necrosis - ✔✔cell proteins are altered or denatured; caused from
hypoxia caused by severe ischemia
