  1. The Muscular Tissues Prepared by : Reem Aldossari

  2. The Muscular Tissues General characteristics of the muscular tissues: • The cells of the muscular tissues are elongated elements, namedmuscle fibers. • The cytoplasm of the muscle fiber, the sarcoplasm, contains myofibrils. These fibrils are made up of the proteins actin and myosin. • The plasma membrane of the muscle fiber is called the sarcolemma. • There are three types of muscle fiber: • Skeletal muscles, which are voluntary and striated. • Smooth muscle, which are involuntary and non- striated. • Cardiac muscles, which are involuntary and striated.

  9. The CELL DIVISTION

  10. The CELL DIVISTION Cell division is a process by which the cellular material is divided between 2 new daughter cells. Mitosis (or indirect division) • occurs in somatic cells of higher organisms. • it is the means of population growth in unicellular organisms. • results in two daughter cells. • have the same number of chromosomes of the mother cell.
