1

muscle tissue is unique because it can

contract
contractile tissue

2

how many types of muscle tissue in body

3

3

what are types of muscle tissue

skeletal
smooth
cardiac

4

skeletal muscle is under _____ control

voluntary

5

skeletal muscles are large and

multinucleated

6

function of skeletal muscles

maintain body postures and position
support soft tissues
guards entrances and exits to the body cavities
helps maintain the body temp

7

muscle tissue has 3 layers of

connective tissue

8

what are 3 layers of muscle tissue

epimysium
perimysium
endomysium

9

epimysium

covers entire muscle
outer layer

10

perimysium

central layer covers individual bundles of fibers

11

bundles of fibers in muscle tissue

fascicle

12

endomysium

inner layer
surrounds individaul muscle fibers

13

what layer are muscle satellite cells found

endomysium

14

what are satellite cells

stem cells

15

end of the muscle fiber come together to form a

tendon

16

tendon otherwise called

aponeurosis

17

what tendon does

attachment of muscle tissue to bone

18

muscles contain

multinucleated
myoblasts

19

myoblasts are

functional cells of the tissue

20

sacrolemma

cell membrane of skeletal muscle cell

21

sacroplasm

cytoplasm of a skeletal muscle cell.

22

the cell membrane has a ______ that maintains the resting membrane potential

transmembrane electrical potential

23

changes in the electrical charge across the membrane result in

rapid contraction of the muscle involved

24

the _______ allow the electrical charge to pass along the whole muscle and stimulate contraction

T tubes or
transverse tubules

25

myofibrils

circular structures that run the entire length of the muscle cell

26

cyofibrils are made up of protien bundles called

myofilaments

27

myofilaments are comprised of

actin and myosin

28

_____ and _____ are responsible for muscle contraction

actin
myosin

29

sacroplasmic reticulum

same as smooth ER

30

sacromere

smallest functional units of myofilaments
