What else can I help you with?
Skeletal muscle fibers differ from typical cells in that these muscle fibers?
contain multiple nuclei and are elongated, allowing for contraction and relaxation to generate movement in the body. They also have a striated appearance due to the arrangement of myofilaments within the cell, which aids in the sliding filament mechanism of muscle contraction.
A skeletal muscle fiber contains many nuclei?
Skeletal muscle fibers contain numerous nuclei. This is used to produce large amounts of the enzymes and structural proteins needed for muscle contraction.
Are Skeletal muscles cells are long and cylindrical with many nuclei?
Cardiac muscle fibers
What type of muscle is involuntary single-ovoid nuclei slow-twitch and has spindle-shaped fibers?
The type of muscle described is smooth muscle. Smooth muscle is involuntary, has single-ovoid nuclei, and contains slow-twitch fibers with spindle-shaped cells. It is found in organs such as the digestive tract and blood vessels.
Which muscle cells have multiple nuclei?
The type of muscle tissue that have only one or two nuclei per cell are cardiac muscle cells. Their nuclei are located in the center of a cell.
Does a skeletal muscle fiber contain many nuclei?
Yes, skeletal muscle fibers are multinucleated, containing multiple nuclei located along the length of the fiber. These nuclei are important for controlling protein synthesis and other cellular activities involved in muscle function and repair.
When viewed under a microscope a sample of tissue reveals striations and long thin fibers that contain many nuclei and mitochondria. What type of tissue is most likely being viewed?
The tissue most likely being viewed is skeletal muscle tissue. Skeletal muscle tissue is composed of long and thin fibers called muscle fibers that exhibit striations due to the arrangement of contractile proteins. These muscle fibers contain multiple nuclei and mitochondria to support their high energy demands.
What kind of muscles are elongated arranged in sheets and contain multiple nuclei?
Skeletal muscles contain elongated muscle fibers arranged in sheets and have multiple nuclei. Smooth muscles and cardiac muscles also have elongated cells, but they are not arranged in sheets and do not have multiple nuclei in each cell.
What are the functions and characteristics of myotubule formation in muscle cells?
Myotubule formation in muscle cells helps in the development and growth of muscle fibers. It plays a role in muscle cell differentiation and organization, leading to the formation of mature muscle fibers. Myotubules are characterized by their elongated shape and multiple nuclei, which contribute to their ability to generate force and contract efficiently.
Why are skeletal muscle fibers unusual?
The skeletal muscle, or striated muscle, is the muscle attached to the skeleton. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons. The contraction of skeletal muscle is under voluntary control.
Why do you have to break down muscle to build it?
What builds muscle is the fusing of "satellite" cells to the muscle fibers. When those cells fuse, they provide nuclei for the growth of the fibers. Different stimuli can cause the cells to move to and fuse with the fibers, such as insulin, growth hormones, and testosterone. When muscle fiber is damaged, growth hormones may stimulate the satellite cells to go to the point of injury and fuse to the fibers, which may result in increased muscle mass. But, it certainly is questionable as to whether the "no pain, no gain" mantra or the injection/ingestion of growth hormones or of testosterone is wise for the building of muscle mass.
Who has more nuclei per cell skeletal muscle or cardiac muscle?
which has more nuclei per cell skeletal muscle or cardiac muscle? I guess that they both have the same number of nuclei.
