Muscle tissues

    Cards (44)

    • Smooth Muscle
      • Main features: Non-striated, spindle-shaped, uninucleated fibers
      • Involuntary muscle
      • Usually covering wall of internal organs
    • The muscle part of the heart is called the myocardium from myo (muscle) + kardia (heart)
    • How do Skeletal Muscles Move?
      1. Muscle pairs are grouped together on the skeleton
      2. Skeletal muscles only pull in one direction and come in pairs
      3. When one muscle of a pair contracts, the other relaxes
    • Striated?

      • 8: Cardiac - Yes
      • 9: Smooth - No
    • Number of nuclei per cell?
      • 10: Skeletal - Multi-nucleated
      • 11: Cardiac - Uninucleated
      • 12: Smooth - Uninucleated
    • Cardiac Muscle
      • Main features: Striated, branched and uninucleated fibers
      • Involuntary muscle
      • Only covering walls of the heart
    • Smooth Muscles
      • Also known as involuntary muscles
      • Appearance: spindle shape with tapered ends, non-striated muscles, and uninucleated cells
      • Function: Controls involuntary movement related to digestion, blood flow, urination, and breathing
      • Located in walls of hollow internal organs such as the intestines, blood vessels, bladder, and airways
    • Muscle Type
      • Skeletal
      • Cardiac
      • Smooth
    • Muscular Tissues
      • Comprised of elongated cells called muscle fibers, capable of contracting to produce movement
    • Cardiac Muscles
      • Also known as myocardium
      • Appearance: branched cylindrical-shaped, striated muscles, and uninucleated cells
      • Function: Controls involuntary movement to rhythmic heartbeat
    • Function of Muscular System
      1. Creates body heat
      2. Moves bones of the Skeletal system
      3. Moves food through Digestive system
      4. Moves blood through Circulatory system
      5. Moves fluids through Excretory system
    • Location
      • 1: Skeletal
      • 2: Cardiac
      • 3: Smooth
    • Muscles are attached to bones by tough cords of connective tissue called tendons
    • EXERCISES: Identify the type of muscle and its type of movement
      1. 13: Skeletal - Voluntary
      2. 14: Cardiac - Involuntary
      3. 15: Smooth - Involuntary
    • Skeletal Muscles
      • Also known as voluntary muscles
      • Appearance: tubular fiber, striated muscles, and multi-nucleated cells (muscle fibers)
      • Function: Controls voluntary movement
      • Either attached to bone or connective tissue
    • Skeletal Muscle
      • Main features: Striated, tubular and multi-nucleated fibers
      • Voluntary muscle
      • Usually attached to skeleton
    • Voluntary or Involuntary
      • 4: Skeletal - Voluntary
      • 5: Cardiac - Involuntary
      • 6: Smooth - Involuntary
    • Series of wave-like muscle contractions that move food through the digestive tract is called peristalsis
    • Prokaryote
      • With true nucleus
      • Membrane-bound organelles
      • For unicellular organism
      • Have polysaccharide capsule
      • Have the DNA & ribosomes
      • Have a gel-like cytoplasm

      • Microscopic
    • What are the four kingdoms of Eukaryota?
    • What are the two kingdoms of Prokaryota?
    • Identify the different types of animal tissue
    • Histology
    • Group of cells that has the same structure and function
    • Epithelial Tissues Location
      Found covering body surfaces (skin), lining body cavities (like the digestive tract, respiratory tract, and blood vessels), and forming glands (such as sweat glands and salivary glands)
    • Classifying Epithelial Tissue
      1. According to Number of Cell layers
      2. According to Cell Shape
