Question 1

Dicrease in amount of tissue or Organ, and they undergo reduction in mass due to decrease in size & number of cells

Answer 1

ATROPHY

Question 2

sample atrophy in physiologic

Answer 2

2. mammary gland involution

Question 3

sample of atrophy in pathologic

Answer 3

1. Disease atrophy
2. denervation of atrophy
   3.persistent cell injury
3. loss of hormonal stimulation
4. aging

Question 4

Mechanism and Biochemistry of atrophy

Answer 4

CATABOLIC PROCESS exeeds ANABOLIC PROCESS

Question 5

in atrophy organelles are removed by?

Answer 5

AUTOPHAGOCYTOSIS

Question 6

sequential mobilization in atrophy

Answer 6

1. SUBCATENOUS FAT- first to use
2. VISCERAL FAT- second to use
3. BONE MARROW

Question 7

this muscle are preseved at the expense of other muscle for locomotion

Answer 7

POSTURAL MUSCLE eg. supraspinatus m.

Question 8

“increase size of an organs” due to increase in cell size without cellular proliferation

Answer 8

HYPERTROPHY

Question 9

this muscle has remarkable capacity to undergo hypertrophy.

Answer 9

CARDIAC M. & SKELETAL M.

Question 10

example of hypertrophy in response to work load:

Answer 10

1. physiology- eg. EXCERCISE
2. pathology- eg. enlargement of MYOCARDIAL FIBERS

Question 11

example of hypertrophy in response to trophic signal.

Answer 11

1. physiologic- uterus and mammary gland
2. pathologic- MYOCARDIAL HYPERTROPHY

Question 12

Mechanism and Biochemistry of hypertrophy:

Answer 12

ANBOLIC process exceeds CATABOLIC PROCESS

Question 13

Gross: of hyopertrophy:

Answer 13

Tissue & organs INCREASE IN SIZE & WEIGHT NOT IN NUMBERS

Question 14

Microscopic anatomy: of hypertrophy:

Answer 14

CELLULAR ENLARGEMENT due to increase of number in size and organelle size.

Question 15

define as an increase in” number of cells” cause an increase in orgam or tissue mass

Answer 15

HYPERPLASIA
