Q

Striated, involuntary and branched

31
Q

Involuntary with no striations

32
Q

The membrane that surrounds the skeletal muscle

33
Q

The change in concentration of this molecule causes muscle contraction to begin

34
Q

The attachment of the molecule in #2 to this regulatory protein allows for muscle contraction to begin

35
Q

This is equivalent to the cell membrane

A

Sarcolemma

36
Q

This is equivalent to the a cell’s cytoplasm

A

Sarcoplasm

37
Q

Calcium is released by this structure to begin a muscle contraction

A

Sarcoplasmic reticulum
