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
