  • Erector spinae group muscles
    Includes iliocostalis, longissimus, and spinalis; they extend and laterally flex the vertebral column and help maintain posture.
  • Function of the quadratus lumborum
    Laterally flexes the vertebral column, helps with lower back extension, and stabilizes the pelvis.
  • Role of the iliopsoas muscle
    Flexes the hip joint and trunk; important for walking, running, and sitting up from lying down.
  • Primary actions of the gluteus maximus
    Extends and laterally rotates the hip; important for rising from sitting, climbing, and running.
  • Functions of gluteus medius and minimus
    Abduct and medially rotate the thigh; stabilize the pelvis during walking.
  • Pelvic floor muscles and their functions
    Includes levator ani and coccygeus; support pelvic organs, assist in continence, and aid childbirth.
  • Main functions of lumbopelvic muscles
    Stabilize and move the lower back and pelvis, enable hip movements, and support pelvic organs.
  • Muscle group responsible for vertebral column extension
    Erector spinae group (iliocostalis, longissimus, spinalis).
  • Muscle that stabilizes the pelvis during walking
    Gluteus medius and minimus.
  • Muscle important for hip flexion and trunk movement
    Iliopsoas (psoas major and iliacus).
  • Muscle group that helps maintain posture in the lower back
    Erector spinae group.
  • Muscle that laterally flexes the vertebral column and stabilizes the pelvis
    Quadratus lumborum.
  • Muscle group that supports pelvic organs and assists in continence
    Pelvic floor muscles (levator ani, coccygeus).
  • Muscle action important for rising from a sitting position
    Gluteus maximus extends and laterally rotates the hip.
  • Muscles involved in hip abduction
    Gluteus medius and minimus.
  • Muscle group that flexes the hip joint
    Iliopsoas.
  • Muscle that helps with lateral flexion of the vertebral column
    Quadratus lumborum.
  • Muscle group that extends and laterally flexes the vertebral column
    Erector spinae group.
  • Pelvic floor muscles role in childbirth
    They support pelvic organs and play a role in childbirth.
  • Importance of lumbopelvic muscles for core stability
    They are essential for posture, core stability, and movements like bending, lifting, and walking.
