What are the long cells called?
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….

Why are skeletal muscle cells long?
Skeletal muscle cells are also long and cylindrical. A skeletal muscle fiber can be up to a foot long! These long, highly specialized cells result from the fusion of many cells and after the cells fuse their individual nuclei are retained. As a result, skeletal muscle fibers are multinucleate.
Does smooth muscle have branching cells?
Smooth muscle has no striations, is not under voluntary control, has only one nucleus per cell, is tapered at both ends, and is called involuntary muscle. It has one nucleus per cell, is branched, and is distinguished by the presence of intercalated disks.
Which cell is known as longest cell?
– In the human body, the nerve cell is the longest cell. Nerve cells are also called neurons that are found in the nervous system. They can be up to 3 feet long.
Which is the longest known cell?
The longest cell is the nerve cell. The largest cell in the human body is female ovum.
Why are skeletal muscles long and cylindrical?
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. Each nucleus regulates the metabolic requirements of the sarcoplasm around it.
Why do muscle cells live longer?
Skeletal muscles contain some of the longest lived cells. However, since muscles undergo wear and tear and sustain injury, your body must repair and replace them, which it does through special satellite and stem cells. Replacement means that over a lifetime, the average age of individual skeletal muscle cells drops.
Which muscles are long and pointed ends and Uninucleate?
The cells are long with pointed ends (spindle-shaped) and uninucleate (having a single nucleus)….
- The muscles of the heart are involuntary in nature and called cardiac muscles.
- The cells are cylindrical in shape, branched and uninucleate.
- The heart muscles show rhythmic contraction and relaxation throughout life.
Are cardiac cells Uninucleate?
Cardiac muscle : Cardiac muscle is a type of involuntary mononucleated, or uninucleated, striated muscle found exclusivly within the heart. Its function is to “pump” blood through the circulatory system by contracting.
What type of muscle has branching cells?
Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks.
Does smooth muscle have long cylindrical cells?
Skeletal muscle cells have long, cylindrical shape; while smooth muscle cells and cardiac muscle cells are spindle-shaped. Moreover, cells in muscle tissue are specialised by their ability to contract, causing movement of body. Both muscle tissue and epithelial tissue have a nerve supply to control them.
What muscle contains cylindrical cells with branching ends?
Involuntarily controlled. Banded striated, single cell nuclei, found in the wall of viscera, has short cylindrical cells with branching ends, gap junction, change the internal volume of an organ, t-tubules, pumps the blood through blood vessels.
What is a cylindrical organelle?
A Centriole is a cylindrical organelle composed mainly of a protein referred to as tubulin. Centrioles are found in most eukaryotic cells. The main function of centrioles is to produce cilia during interphase and the aster and the spindle during cell division.
