Flashcards in Block 2 Three Kinds of Muscle Deck (45):
1

muscle cells are unique because they have the ability to blank

shorten

2

type of muscle in childbirth

smooth

3

muscle cell is aka blank

fiber

4

cytoplasm of muscl cell is aka

sarcoplasm

5

muscle cell plasma membrane is aka

sarcolemma

6

smooth er of muscle cell is aka

sarcoplasmic reticulum

7

this means soft, fleshy, meaty part of body which is muscle

sarco

8

two types of myofilaments

actin, myosin

9

type of epithelium in vas deferens

pseudostratified epithelium

10

skeletal muscle cells are generallly blank when transversely cut

round/oval

11

skeletal muscle has blank nucleus

multi

12

nuclei of muscle cell is placed where?

outside of the cell

13

there are blank of ct in muscle

layers

14

individual fascicles are enclosed by blank

perimysium

15

individual muscle fibers are enclosed by blank

endomysium

16

groups of fascicles are enclosed by blank

epimysium

17

outer epimysium is aka blank

deep fascia

18

tendons and ligaments are strong and resist stretch because they are made of blank and blank

collagen, dense regular ct

19

epimysium is aka blank in tendon

epitendineum

20

epimysium is aka blank in nerves

epineurium

21

fibers of tendon that actually insert into bone and are super strong

sharpeys fibers

22

ligament tear = pull = blank

strain/sprain

23

torn tendon has blank that remove injured cells

macrophages

24

torn tendon has blank that produce collagen to bridge the injured tendon

fibroblasts

25

macrophages come from blank

monocytes

26

myosin filament slides into the blank band during the sliding filament theory in muscle contraction

a

27

area between z lines area aka blank and can shorten and lengthen

sarcomere

28

during muscle contraction, these bands shorten

i, h

29

during muscle contraction, this band does not change

a

30

membrane that dips into the membrane of the skeletal muscle and is involved in action potentials

t tubules

31

three types of cardiac muscle

contractile cells, pacemaker cells, conduction cells

32

ventricles and atria have the blank type of muscle cells

contractile

33

sa and av nodes have blank type of muscle cells

pacemaker

34

bundle of his and purkinje fibers are this type of cardiac muscle

conduction

35

contractile cells of heart are blank unlike other cells

striated

36

heart only has this layer of muscle

endomyseum

37

heart is filled with blank

capillaries

38

cardiac muscle fibers blank unlike skeletal muscle

branch

39

the longitudinal longitudinal part of intercalated disc has blank junctions

gap

40

transverse part of intercalated disk has blank junctions

tight adherent

41

gap junction is aka blank

nexus

42

at the z lines, where actin filaments bind to proteins of the membranes there is a large spot compared to zonula and macula adherens called blank

fascia adherens

43

cardiac muscle does not have the ability to bring enough calcium about to make a contraction because it has an under developed blank compared to skeletal muscle

sarcoplasmic reticulum

44

lack of calcium in heart leads to blank heartbeat

weak

45

too much calcium in heart leads to blank heartbeat

fast irregular
