What do skeletal muscle cells have more of?

Skeletal muscle cells are long, cylindrical, and striated. They are multi-nucleated meaning that they have more than one nucleus. This is because they are formed from the fusion of embryonic myoblasts.

What do muscle cells have more of than other cells?

Muscle cells are assiciated with a large number of mitochondria as they require more ATP (energy) to function than other cells. … So the cell needs lots of ATP. And mitochondria (the powerhouse of the cell) function to respire carbohydrates to produce ATP.

What is unique about skeletal muscle cells?

Four characteristics define skeletal muscle tissue cells: they are voluntary, striated, not branched, and multinucleated. … The structure of skeletal muscle cells also makes them unique among muscle tissues.

What organelles do skeletal muscle cells have a lot of?

During strenuous exercise, the rate of energy use in skeletal muscles can increase by more than 100-fold almost instantly. To meet this energy demand, muscle cells contain mitochondria. These organelles, commonly referred to as the cell’s “power plants,” convert nutrients into the molecule ATP, which stores energy.

How are skeletal muscle cells different from other cells?

Skeletal muscle cells form elongated fibers in the body. They have multiple nuclei within each cell. This contrasts with the majority of other cells in human bodies. They also contain many mitochondria, cellular organelles that produce adenosine triphosphate (ATP), the body’s fuel.

Why do skeletal muscle cells have more mitochondria?

Explanation: Muscle cells need energy to do mechanical work and respond quickly. Thus a higher number of mitochondria is present so that the cells requirement of energy to perform its specific function is fulfilled.

Why do skeletal muscle cells contain more than one nucleus?

Skeletal muscle cells are multinucleated because during prenatal development, several cells fuse together to create each developed muscle cell (hence the presence of several nuclei).

What cells are in skeletal muscle?

The Skeletal Muscle Fiber. Skeletal muscle cells or fibers are highly elongated cells with a very elastic and resistant plasma membrane, called the sarcolemma. Fibers are characterized by the presence of numerous nuclei located at the periphery of the cell, hence muscle fibers are described as a syncytium.

Why do muscle cells have more mitochondria than fat cells?

This is because mitochondria produce ATP during aerobic respiration and ATP is needed for muscle to contract. … Muscles cells contain more mitochondria because they have to release large amount of energy quickly for movement.

What type of muscle cells have more than one nucleus quizlet?

skeletal muscle cells contain more than one nucleus.

How do muscle cells interact with other cells?

Muscle precursor cells become activated accompanied by differentiation and fusion during both muscle growth and regeneration; inter-cellular communication is required for successful completion of these processes. Cellular communication is mediated by lipids, fusogenic membrane proteins, and exosomes.

What cell has more than one nucleus?

Multinucleate cellsMultinucleate cells (multinucleated or polynuclear cells) are eukaryotic cells that have more than one nucleus per cell, i.e., multiple nuclei share one common cytoplasm.

What type of muscle cells have one nucleus?

Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations. They are called involuntary muscles. Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks.

Do all muscle cells only have one nucleus?

Explanation: Skeletal muscle tissue has the most nuclei out of the different types. Cardiac has one or two nuclei per fiber, and smooth muscle cells only have one.

How are smooth and skeletal muscle cells different quizlet?

Skeletal muscle is attached to bones, has cylindrical cells, is striated, multinucleate, and voluntary control. … Smooth muscle is in walls of hollow organs, spindle-shaped cells, nonstriated, uninucleate, and involuntary.

Do skeletal muscles have branched cells?

Skeletal muscle also has multiple nuclei present in a single cell. … It has one nucleus per cell, is branched, and is distinguished by the presence of intercalated disks.

What are the differences among a skeletal muscle fiber a skeletal muscle Myofibril and a skeletal muscle protein filament?

8-3 What are the differences among a skeletal muscle fiber, a skeletal muscle myofibril, and a skeletal muscle protein filament? A muscle fiber is one muscle cell. The muscle fiber is made up of many muscle myofibrils. Within the myofibrils are muscle the protein filaments myosin and actin.

Why do skeletal muscle cells appear striped?

The striated appearance of skeletal muscle tissue is a result of repeating bands of the proteins actin and myosin that are present along the length of myofibrils. Dark A bands and light I bands repeat along myofibrils, and the alignment of myofibrils in the cell causes the entire cell to appear striated or banded.

Why are muscle cells branched?

They are branched to bring information between one cell to the other while the muscle cells formed by the spindle are that way because support is their key function. Note: There are several nuclei in a single muscle cell, which are forced against the cell membrane.

Are muscle cells controlled individually or in groups?

Muscles are highly specialized to contract forcefully. Muscles are powered by muscle cells, which contract individually within a muscle to generate force. This force is needed to create movement.
