Answer 5

contracted

Question 6

caveolae

Answer 6

invaginations of the smooth and cardiac muscle membrane, analogous to T tubules

Question 7

what type of tissue is endomysium

Answer 7

loose CT

Question 8

Toponin I

Answer 8

inhibits binding of myosin to actin

I (isotropic) bands

Question 14

cellular inclusions of striated muscle

Answer 14

glycogen

Question 15

CT that connects muscle to bone

Answer 15

tendon (dense reg CT continuous with endo-, peri- and epimysium)

Question 16

intercalated discs: definition and location according to sarcomere

Answer 16

cardiac cell adhesion structures with lateral and transverse specializations. Found at the Z-line (terminal end of the myofibrils)

Question 17

does smooth muscle have endomysium

Answer 17

Yes- secreted reticular fibers rather than fibrocytes of skeletal endomysium

Question 18

junctional folds

Answer 18

the creases in the sarcolemma that increase surface area at the motor end plate

bag cell (large) chain cell (small)

Question 20

features of cardiac tissue

Answer 20

spaces between the cells and only one or two nuclei not on periphery of the cell
