striated

Examples of striated in the following topics:

• Characteristics of Muscle Tissue

  • Muscle tissue can be classified functionally, voluntary or involuntary and morphologically striated or non-striated.
  • Morphologically skeletal myocytes are elongated and tubular and appear striated with multiple peripheral nuclei.
  • As with skeletal muscle cardiac muscle is striated, however it is not consciously controlled and so is involuntary.
  • Smooth muscle is non-striated, although it contains the same myofilaments they are just organised differently, and involuntary.
  • Cardiac and skeletal muscle are both striated in appearance, while smooth muscle is not.

• Types of Muscle Tissue

  • Skeletal muscles are voluntary and striated in nature that allow movement of an organism by the deliberate generation of force.
  • Skeletal muscle is striated, multinucleate, and involuntary.
  • It is generally uninucleate, but is striated.
  • Cardiac muscle is striated, similar to skeletal muscle, but beats involuntarily.

• Structure and Function of the Muscular System

  • Muscle tissue can be classified functionally as voluntary or involuntary and morphologically as striated or non-striated.
  • Morphologically skeletal myocytes are elongated and tubular and appear striated with multiple peripheral nuclei.
  • As with skeletal muscle, cardiac muscle is striated; however it is not consciously controlled and so is classified as involuntary.
  • Smooth muscle is non-striated and involuntary.

• Microscopic Anatomy

  • Cardiac muscle appears striated due to the presence of sarcomeres, the highly organized basic functional unit of muscle tissue.
  • Cardiac muscle, like skeletal muscle, appears striated due to the organization of muscle tissue into sarcomeres.

• Skeletal Muscle Fibers

  • Skeletal muscles are composed of striated subunits called sarcomeres, which are composed of the myofilaments actin and myosin.
  • The regular organization of these sarcomeres gives skeletal and cardiac muscle their distinctive striated appearance.

• Esophagus

  • The esophageal tube in humans is comprised of two main layers of smooth muscle, though striated muscle comprises the tube near the pharynx.

• Oculomotor (III) Nerve

  • The muscles it controls are the striated muscle in the levator palpebrae superioris and all extraocular muscles except for the superior oblique muscle and the lateral rectus muscle.

• Urethra

  • The external urethral sphincter is a striated muscle that allows voluntary control over urination by controlling flow of urine from the bladder into the urethra.

• Tetanus

  • Tetanus affects skeletal muscle, a type of striated muscle used in voluntary movement.
  • The other type of striated muscle, cardiac or heart muscle, is not affected by the toxin because of its intrinsic electrical properties.

• The Cardiac Cycle

  • Cardiomyocytes are distinctive muscle cells that are striated like skeletal muscle, but pump rhythmically and involuntarily like smooth muscle; they are connected by intercalated disks exclusive to cardiac muscle .
