A. Smooth Muscle

• Main Parts:

  1. Smooth muscle cells

  2. Nucleus

  3. Cytoplasm

• Function:

  • Involuntary contractions

  • Move substances (like food, blood, urine) inside the body

• Location:

  • Walls of internal organs (stomach, intestines, blood vessels, bladder, uterus)

B. Cardiac Muscle (Heart Muscle)

• Main Parts:

  1. Cardiac fibers

  2. Intercalated discs

  3. Nucleus

  4. Striations

• Function:

  • Pump blood continuously

  • Coordinate heartbeats (synchronized contraction)

• Location:

  • Found only in the heart (myocardium layer)

C. Bone Marrow

• Main Parts:

  1. Hematopoietic cells

  2. Adipocytes (fat cells)

  3. Bone trabeculae

• Function:

  • Produce blood cells (red, white, platelets)

  • Store fat for energy

  • Provide structural bone support

• Location:

  • Inside bones (especially pelvis, sternum, femur, humerus)

Quick Tips:

• Smooth Muscle = No stripes, slow movement

• Cardiac Muscle = Branched + striped + strong rhythmic contraction

• Bone Marrow = Blood cell factory inside spongy bones
