1

Etiology

cause

2

pathogenesis

sequence of events

3

outer muscles attached to bone

tendons

4

how do we sense characteristics of objects

size and shape, color, texture, consistency, smell, sound

5

colour

least useful due to artifacts, maters in a living matient

6

texture

slick, smooth, rough, must know change from normal (liver should be smooth, if rough then pathogenic)

7

consistency

something firm goes soft

8

smell

not so much in pathology but in clinical setting; bad breath in lung tumors

9

sound

not used much in pathology but in path but in a patient eg using steth

10

how can a smooth surface change to rough

addition of material eg. Protein on heart leaking out of vessels in pericarditis

11

how can a smooth surface change to rough (2)

take material away--necrosis ex. Untreated hypertensive patient's kidney may shrink and look rough due to necrosis

12

in and end artery system where there is not enough blood supply, necrosis occurs in the shape of a

V (2D) / cone (3D)

13

when there is hypertension the ___ of the kidney will die first bc__..

cortex bc it_s the most hypoxic area

14

in long standing hypertension the renal vessesl get___..bc___..

get thicker bc the tissue is hyperplastic, this leads to vessel narrowing, reduced blood supply and necrosis of the cortex

15

a hypertensive kidney weill show

an area that is gone (v shape maybe) and lots of little blue cells (PMNs due to inflammation)

16

how can a smooth surface change to rough (3)

add and remove things, liver will be smaller but nodular due to alcoholism or hep C

17

2 components of cirrhosis

scarring and regeneration

18

appearance of nodules formed in cirrhosis

are not functional due to lack of blood supply and get surrounded by scar tissue

19

fibrosis

just scarring

20

blue - CT/scar tissue pink - muscle
