What are two terms for a muscle cell?

A muscle cell is also known as a myocyte when referring to either a cardiac muscle cell (cardiomyocyte), or a smooth muscle cell as these are both small cells. A skeletal muscle cell is long and threadlike with many nuclei and is called a muscle fiber.

What are the key features of a muscle cell?

Muscle cells contain filaments of protein that slide over each other to cause muscle contraction. The arrangement of these filaments causes the banded appearance of heart muscle and skeletal muscle. They contain many well-developed mitochondria to provide the energy for muscle contraction.

What is the most common muscle cell?

Skeletal muscle
Skeletal muscle is the most common and widely distributed muscle tissue in the body, making up around 40% of the body’s total mass. It forms all of the skeletal muscles, such as the biceps brachii and gluteus maximus, and is found in the eyes, throat, diaphragm, and anus.

What is the term for a muscle cell?

Mature contractile cells, commonly known as myocytes, that form one of three kinds of muscle. The three types of muscle cells are skeletal (MUSCLE FIBERS, SKELETAL), cardiac (MYOCYTES, CARDIAC), and smooth (MYOCYTES, SMOOTH MUSCLE). They are derived from embryonic (precursor) muscle cells called MYOBLASTS.

What is another term for muscle cells?

Muscle cells, commonly known as myocytes, are the cells that make up muscle tissue. There are 3 types of muscle cells in the human body; cardiac, skeletal, and smooth. Cardiac and skeletal myocytes are sometimes referred to as muscle fibers due to their long and fibrous shape.

Which best explains why muscle is considered a tissue?

Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.

Where are muscle cells found?

Smooth muscle fibers are located in walls of hollow visceral organs (such as the liver, pancreas, and intestines), except the heart, appear spindle-shaped, and are also under involuntary control. Skeletal muscle fibers occur in muscles which are attached to the skeleton.

What is muscle cell function?

Muscle fibers consist of a single muscle cell. They help to control the physical forces within the body. When grouped together, they can facilitate organized movement of your limbs and tissues.

Which explains best why muscle cells are different from blood cells?

Which best explains why muscle cells are different from blood cells? … Different genes are activated in muscle cells than in blood cells. Muscles cells experience different environmental influences than blood cells. Muscle cells are produced by the brain, but blood cells are produced by the heart.

Which best explains why muscle cells look different from blood cells?

Which best explains why muscle cells are different from blood cells? A mutation occurs during the development of muscle cells but not in blood cells. Different genes are activated in muscle cells than in blood cells.

What is the composition of muscle?

Muscle Biochemical Composition

Skeletal muscles contain approximately 75% water, 20% protein, 1–10% fat, and 1% glycogen. The biochemical properties of the major muscle components (i.e., myofibers, connective tissue, and adipose tissue) are described in the following.

Which statement best explains why muscle cells have more mitochondria than skin cells?

There are more mitochondria in muscle cells than there are in skin cells. … Cells that are more active and/or move more will require a greater energy produced via cellular respiration. Therefore, cells that are more active usually contain more mitochondria than cells that are not as active.

Which statement best explains why muscle cells contain higher numbers of 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.

Which best explains why muscle cells have more mitochondria than skin cells?

20. Which statement best explains the reason muscle cells have more mitochondria than skin cells? A. Muscle cells use more energy than skin cells.

Why is there mitochondria in muscle cells?

Skeletal muscles are made of long, thin cells that are packed with highly organized proteins and organelles. … 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.

What do specialized cells make up?

Specialized cells make up tissues, tissues make up organs, and organs make up the systems that work together to make up our bodies. Nerve cells, blood cells, and reproductive cells are examples of specialized cells.

Where is the mitochondria located in a muscle cell?

Ogata and Yamasaki used electron microscopy to provide the first detailed description of mitochondrial localization in adult mammalian skeletal muscle (Ogata and Yamasaki, 1985). These studies revealed that mitochondria are located within the I-band, adjacent to the CRU on either side of the Z-line.

Which type of muscle cell has the most mitochondria?

heart muscle cells
A. Your heart muscle cells – with about 5,000 mitochondria per cell. These cells need more energy, so they contain more mitochondria than any other organ in the body!

What cells are found in skeletal muscle?

All Answers (12) In normal muscle you can find: muscle fibers, satellite cells, all types of connective tissue cells ( mast cells, fibroblasts, adipose cells, occasionally plasma cells and lymphocytes, dendritic cells) and components of nerves and blood and lymphatic vessels.

Do muscle cells have the most mitochondria?

Muscle cells have the most number of mitochondria in a human body. That includes the cardiac cells as well(because, the heart is also a muscular chamber, if you’re not familiar). Their energy demand is very high compared to the other cells in the body, due to constant contraction and elongations.
