  • What are muscle cells commonly called?
    Muscle cells are commonly called myocytes or muscle fibers.
  • What are myofilaments and what is their role in muscle tissue?
    Myofilaments are protein filaments in muscle cells that allow for muscle contraction.
  • How does the structure of muscle tissue contribute to its function?
    Muscle tissue consists of tightly packed cells, which enhances its ability to generate contractile force for movement.
  • What is the significance of the root 'myo' in terms like myocyte and myofilament?
    The root 'myo' means muscle, indicating that myocytes are muscle cells and myofilaments are muscle filaments.
  • How do blood vessels support the function of muscle tissue?
    Blood vessels provide nutrients and oxygen to muscle tissue and help remove waste products like carbon dioxide.
  • What are muscle cells commonly called?
    Muscle cells are commonly called myocytes or muscle fibers.
  • What are myofilaments and what is their role in muscle tissue?
    Myofilaments are protein filaments in muscle cells that allow for muscle contraction.
  • How does the structure of muscle tissue contribute to its function?
    Muscle tissue consists of tightly packed cells, which enhances its ability to generate contractile force for movement.
  • What is the significance of the root 'myo' in terms like myocyte and myofilament?
    The root 'myo' means muscle, indicating that myocytes are muscle cells and myofilaments are muscle filaments.
  • How do blood vessels support the function of muscle tissue?
    Blood vessels provide nutrients and oxygen to muscle tissue and help remove waste products like carbon dioxide.
  • What is the term for abnormally increased muscle function or activity?
    Abnormally increased muscle function or activity is referred to as hyperactivity or hyperfunction of muscle tissue.
  • Which type of muscle tissue contains intercalated discs?
    Cardiac muscle tissue contains intercalated discs.
  • How does muscle tissue contribute to heat production in the body?
    Muscle tissue contributes to heat production by using ATP during contraction, which generates heat as a byproduct.
  • When a muscle is relaxed, is it in a shortened or lengthened state?
    When a muscle is relaxed, it is in a lengthened state compared to when it is contracted.
  • What is the most distinguishing characteristic of muscle tissue?
    The most distinguishing characteristic of muscle tissue is its ability to contract and generate force for movement.
  • What do neurons and muscle cells have in common?
    Neurons and muscle cells both use electrical signals to initiate responses; muscle cells respond by contracting, while neurons transmit nerve impulses.
  • What is the primary function of muscle cells?
    The primary function of muscle cells is to contract and generate force, enabling movement of the body.
