Flashcards in Muscle - BSC Deck (22):
1

anesthesia

?

2

cryesthesia

?

3

kinesthesia

detection of bodily position, weight, or movement of muscles, tendons, or joints

4

paresthesia

skin sensation with no apparent cause

5

synesthesia

?

6

paralysis

loss of motor function

result of an interruption of one or more motor pathways can occur at any point between cerebrum and muscle fiber

7

anesthesia

total or partial loss of sensation, especially tactile sensibility, can be induced by disease, injury, or anesthetic drugs

8

loss of nerve causes?

atrophy

9

apoptosis

programmed cell death

10

atrophy

?

11

dystrophy

form artophy specifically result of disease

12

necrosis

cell death (from external cause)

13

myopathy

muscle disease affecting muscle cell causing it to function improperly

14

denervation?

no necrosis of muscle cell (myonecrosis)

loss and disarray of myofilaments

don't see rabdomyelosis***

15

sarcomere

Z line to Z line

16

skeletal muscle

voluntary contraction
peripheral contraction

17

primary cause of myofilament degradation in denervation atrophy?

increased proteosome activity

muscle cells tries to save energy and material so it ubiquinates

18

what products do lysosomes degrade

?

19

metalloproteinase?

extraacellular matrix activity

20

caspase?

play role in apoptosis and necrosis

21

proteosome

degrade proteins from cytoplasm

22

ubiquitin proteosome system

two successive steps
-target protein ubiquilated (need 4)***
-26S proteosome recognizes ubiquitin and degrades substrate
