PPT-MYB: muscle cells use MYB to accelerate O

2 diffusion and act as localized O 2 reserve MYB increases O 2 solubility Very abundant in marine mammals Not found in blood Myoglobin MYB Binds reversibly to O 2 a helical globin fold 8 helices AH. What is Muscle Tissue?. Composed of cells that are highly specialized to shorten in length by contractility.. Made up of cells that are called . myocytes. ..

Pushing the Limits: Muscle Fibers.  . 10:39: Describe skeletal muscle fibers (muscle cells)..  . 11:21 How many skeletal muscle fibers do we normally use at any one time?. # 1 Cheek Cells. These cells were gently scraped from the inner surface of a person’s cheek, and placed on a microscope slide. The cheek lining cells are thin and flat. They fit together like tiles on a floor, except that they overlap slightly. Because they are thin and flat and several layers thick these cells make the lining of the cheek smooth, flexible, and strong. The large dark spot in the center of each cell is the nucleus. . Contractile. Made of contractile proteins. Cells are called fibers. Skeletal Muscle. 40% of body weight. Under voluntary control; attached to skeleton. Striated, or banded, appear. ance. Cells have multiple nuclei.
