17

Fascia

Layers of dense connective tissue; surrounds each muscle and may project beyond the ends of its muscle fibers, forming cordlike tendon.

18

Tendon

A flexible but inelastic cord of strong fibrous collagen tissue attaching a muscle to a bone.

19

Aponeurosis (plural: aponeuroses)

A sheet of pearly-white fibrous tissue that takes the place of a tendon in sheetlike muscles having a wide area of attachment.

20

Myofibrils

Any of the elongated contractile threads found in striated muscle cells.

21

Myosin

A fibrous protein that forms (together with actin) the contractile filaments of muscle cells and is also involved in motion in other types of cells.

22

Actin

A protein that forms (together with myosin) the contractile filaments of muscle cells, and is also involved in motion in other types of cells.

23

Sarcomere

A structural unit of a myofibril in striated muscle, consisting of a dark band and the nearer half of each adjacent pale band

24

Titin

A protein important in the contraction of striated muscle tissues

25

Troponin

A globular protein complex involved in muscle contraction. It occurs with tropomyosin in the thin filaments of muscle tissue

26

Tropomyosin

A protein involved in muscle contraction. It is related to myosin and occurs together with troponin in the thin filaments of muscle tissue

27

Sarcoplasmic reticulum

A specialized form of endoplasmic reticulum surrounding myofibers. A membrane system responsible for storing, releasing, and resequestering calcium in response to an action potential.

28

Transverse tubule

a deep invagination of the sarcolemma, which is the plasma membrane, only found in skeletal and cardiac muscle cells

29

Cisternae

a sac or cavity containing fluid.

30

Triad

The structure formed by a T tubule with a sarcoplasmic reticulum (SR) known as the terminal cisterna on either side.
