Muscle Tissue (vocab, types, macroscopic, & microscopic anatomy)

Front

What is the role of mitochondria in muscle contraction?

Back

The production of ATP.

Front

What connective tissue surrounds individual muscle cells?

Back

Endomysium.

Front

Identify this type of muscle tissue: Cardiac, Skeletal, or Smooth?

Back

Cardiac.

Front

What is the purpose of calcium in muscle contraction?

Back

To bind to troponin, move tropomyosin, and expose actin's binding sites.

Front

What connective tissue covers the entire muscle?

Back

Epimysium.

Front

Define skeletal muscle tissue.

Back

Striated muscle tissue that is under voluntary control and is responsible for movement.

Front

What is the function of the sarcolemma?

Back

It is the cell membrane of a muscle cell that conducts electrical impulses.

Front

What are myofibrils?

Back

Long, thread-like structures within muscle cells that contain the contractile proteins actin and myosin.

Front

What is the sliding filament theory?

Back

The theory that muscle contraction occurs when actin filaments slide over myosin filaments, shortening the muscle.

Front

What is the role of troponin in muscle contraction?

Back

Troponin binds calcium and causes a conformational change that allows muscle contraction to occur.
