The muscle system made up of cells that are long, thin, and pointed is the cardiac muscle system. Cardiac muscle cells are unique in structure and function, as they are found in the heart and have a branching, interconnected appearance. These cells contract rhythmically to pump blood throughout the body.
A muscle is made up of many fasicles. These fasicles contain myofibrils. The myofibrils contain sarcomeres which contain myosin and actin filaments which is the molecular movement for muscle contraction.
Skeletal muscle cells are very thin, and lean. They are designed for contraction and expansion.
Skeletal muscle cells are much bigger than cardiac muscle cells. Skeletal muscle fibres are up to 100 micrometers in diameter and several centimeters long while cardiac myocytes are about 15 micrometers in diameter and about 100 micrometers long.
thick and thin bands (lines) of filaments.
muscle cells...
The long thin process that carries impulses away from the cell body is called an axon. Axons are part of nerve cells (neurons) and transmit electrical signals to other neurons or muscle cells.
Actin is the protein that forms the contractile thin filaments of muscle cells in the human body. It plays a key role in muscle contraction by interacting with myosin to generate the force required for muscle movement.
No,there are different shapes of cells in human body such as :- spiral,collumner,ellipitcal etc.. Our muscle cells are very long and thin whereas the cells present in our eyes a in cone-shaped.
