Question 11

• When Skeletal muscle stimulates, it contracts by what?, When it relaxes it_____

Answer 11

Nerve Stimuli

Stops

Question 12

• The cells in skeletal muscle are long cylinders separated by what?

Answer 12

Connective tissue

Question 13

• Does Smooth Muscle have striations? Why or why not?

Answer 13

It does not, more than likely because it is not stimulated by nerve stimuli and doesn’t require voluntary movement – and doesn’t have striations

Question 14

• What is Caveolae in Smooth Muscle? What does it do?

Answer 14

a role in the cell signaling

Question 15

• What are 3 characteristics of Smooth Muscle?

Answer 15

Involuntary, lack striations, move by peristalsis

Question 16

• What are 3 characteristics of the Cardiac Muscle?

Answer 16

Involuntary, make up the bulk of the heart, joined by intercalated discs.

Question 17

• What are intercalated discs in cardiac muscle?

Answer 17

link the cells together and define their borders

Question 18

• How is the Cardiac Muscle different from both Skeletal Muscle and Smooth Muscle?

Answer 18

Its cells branch and are joined to one another via intercalated discs

Question 19

• As far as the Cardiac Muscle is concerned, what is 1 thing similar to that and the Skeletal Muscle and 1 thing similar to that and the Smooth Muscle?

Answer 19

Skeletal: both are striated

Smooth: nuclei is centrally located.
