Applied Pathophysiology for the Advanced
Practice Nurse 1st Edition by Dlugasch & Story
(All Chapters 1-14 | Verified Q&A)
-plasia - cell formation
-trophy - SIZE
Atrophy - cells decrease in size and number due to decreased work demand. Attempt to
conserve energy
Causes of ATROPHY - disuse, denervation, endocrine hypofunction, inadequate nutrition and
ischemia
Causes of dysplasia - HPV, smoke exposure
Causes of Metaplasia - chronic irritation and inflammation such as chronic smoking, and vitamin
A deficiency
Dyplasia definition - cells mutate into cells of a different size, shape and appearance; this is an
abnormal process
Dysplasia AKA - atypical hyperplasia; implicates precancerous cells
Examples of ATROPHY - muscle shrinking in cast; paralyzed extremity; ovaries shrink w/ less
estrogen circulating (menopause)
Examples of dysplasia - at the cervix or respiratory tract
