What are the striated appearance of skeletal muscle fiber is mainly due to?
cardiac muscle appears striated like the skeletal muscle due to arrangement of contractile proteins
What muscle appears striped under the microscope?
don't worry i got your back i took the assesment on connections academy and the answer is ...... B. Skeletal. i think tht i spelt it right
Why does skeletal muscle appear striated when viewed through a microscope?
Skeletal muscle appears striated due to the arrangement of the actin and myosin filaments within muscle fibers. The alternating light and dark bands represent the organization of these filaments, creating the striated pattern. This organization is essential for muscle contraction and force generation.
Muscle that appears banded?
The muscle that appears banded is skeletal muscle. Its banded appearance, known as striations, is due to the arrangement of muscle fibers and the presence of overlapping sarcomeres containing actin and myosin filaments. Skeletal muscle is responsible for voluntary movements in the body.
What distinguishes the appearance of each muscle types?
Skeletal muscle appears striated and is multinucleated, with long, cylindrical fibers that are under voluntary control. Cardiac muscle also has striations but consists of shorter, branched fibers with a single central nucleus, and it operates involuntarily. Smooth muscle lacks striations, has spindle-shaped fibers, and is also involuntary, featuring a single central nucleus. Each type's unique structure reflects its specific function in the body.
What does cardiac tissue look like?
Cardiac tissue, or cardiac muscle, appears striated under a microscope, similar to skeletal muscle, but its fibers are branched and interconnected, forming a network. The cells, called cardiomyocytes, are typically cylindrical and have a single, centrally located nucleus. Intercalated discs, which are specialized junctions, can be seen between the cells, facilitating synchronized contractions. Overall, cardiac tissue exhibits a unique combination of structural features that enable its vital role in pumping blood throughout the body.
Why are smooth muscles called smooth?
Smooth muscle is no way connected to the skeleton, example intestine liver etc. Where as striated muscle is connected to skeleton so it is called striated muscle. And the third type of muscle is Cardiac Muscle. --------------------------- Smooth muscle lack the sarcomeres that give skeletal and cardiac muscles their 'striated' appearance. Skeletal muscle isn't "called striated" because it it attached to the skeleton, it is called striated because sarcomeres give muscle a striated appearance. Thus the name, smooth muscle for looking smooth without striation.

Striations in striated muscle result from?
Striated muscle appears stripped due to the parallel alignment of many muscle fibers side to side with their sarcomeres lined up. The striations across each cell are caused by the overlap of the contractile proteins actin and myosin. Actin is the main protein of thin filaments and myosin is in the thick filaments. When actin and myosin are overlapped the darkest band appears( A band), when only actin is present a lighter band, is seen (I band).
What two bands of the sarcomere do we see as the striations in the skeletal muscle?
The striations in skeletal muscle are primarily due to the arrangement of two bands in the sarcomere: the A band and the I band. The A band consists of thick filaments (myosin) and appears darker, while the I band contains thin filaments (actin) and appears lighter. The alternating pattern of these bands creates the characteristic striated appearance of skeletal muscle. Additionally, the Z line, which defines the boundaries of each sarcomere, is also visible and contributes to the striated pattern.
