Skeletal Muscle (as well as Cardiac Muscle) have striations do to their sarcomere's anatomy. The sarcomere is the functional unit of the muscle and appears striated because the different thick and thin filaments present.
The striations in a skeletal muscle cell are the visible parts of the scaffolding of the actin/myosin fibers within the cell. These are the parts the actin/myosin fibers are pulling against.
Thick and thin filaments. Don't cheat on your homework though kid.
muscles have filiments, some are thick and some are thin ,the alternating of these filiments are called striations. The thick filiment is called Myosin, and the thin filiment is called Actin.
The striations that are evident in skeletal muscle are due to the areas between the sacromeres that is referred to as the Z-lines.
the arrangement of myofilaments
Arrangement of myofilaments in the myofibrils
the altering thick and thin filaments
The pattern of actin and myosin.
Intercalated discs and striations suggest the presence of cardiac muscle. Only cardiac muscle has intercalated discs. Both skeletal and cardiac muscle have striations.
Striations are light and dark bands on skeletal and caridac muscle fibers. Smooth muscle lacks striations
Smooth muscle contains no striations whereas cardiac and skeletal muscles are striated.
Striations
On rocks - they are the parallel groves or scratches. Or on skeletal or cardiac muscle: they are the "strands" of the muscle.
The alternating A and I bands on the miofibrils.
Visible bands in cardiac and skeletal muscle are called striated muscles.
Skeletal muscle is one of the three types of muscle and it is a structure of a striated muscle tissue. The muscle is made up of myocytes or muscle fibers.
Of the three types of muscle, cardiac, smooth and skeletal, skeletal is striated. Myocytes form myoblast which form myofibers. The myofibers are composed of myofibrils which are comprised of sarcomeres which is responsible for the muscles striated appearance.
Striations are cause by pooling of blood after death in the direction of where the body originally was before being moved.My answer would be....The arrangement of myofilaments(actin/ myosin) on a myofibril produce the striations of a skeletal muscle cell . Also myofibrils align to give distinct bands. :)Hope that helps :D
Yes, skeletal muscles are voluntary, meaning they can be intentionally controlled. This distinguishes them from the cardiac muscle (heart) and smooth muscles, which are involuntary.
Both types of muscles have striations in their cells for greater contraction. These striations are in the form of crossing and alternating light and dark bands.
