  • What is the vertebral column composed of?
    The vertebral column is made up of a series of bones called vertebrae.
  • What are the main functions of the vertebral column?
    Protect the spinal cord, support the head and trunk, allow flexible movement, and serve as attachment points for ribs and muscles.
  • How many cervical vertebrae are there and where are they located?
    There are 7 cervical vertebrae located in the neck (C1–C7).
  • What is the function of the cervical vertebrae?
    They support the head and allow for its movement.
  • What is the atlas vertebra and its function?
    The atlas is the first cervical vertebra (C1) that supports the skull.
  • What is the axis vertebra and its function?
    The axis is the second cervical vertebra (C2) that allows the head to rotate.
  • How many thoracic vertebrae are there and where are they located?
    There are 12 thoracic vertebrae located in the upper and mid-back (T1–T12).
  • What is the role of thoracic vertebrae?
    Each thoracic vertebra attaches to a pair of ribs, helping form the rib cage and protect the heart and lungs.
  • How many lumbar vertebrae are there and where are they located?
    There are 5 lumbar vertebrae located in the lower back (L1–L5).
  • What is special about lumbar vertebrae?
    They are the largest and strongest vertebrae, supporting most of the body’s weight and allowing bending and twisting.
  • What is the sacrum and its function?
    The sacrum is a triangular bone formed by fusion of five sacral vertebrae; it connects the spine to the hip bones and supports upper body weight.
  • How many sacral vertebrae fuse to form the sacrum?
    Five sacral vertebrae fuse to form the sacrum.
  • What is the coccyx and its function?
    The coccyx, or tailbone, is formed by fusion of four small coccygeal vertebrae and provides attachment for pelvic floor ligaments and muscles.
  • How many coccygeal vertebrae form the coccyx?
    Four coccygeal vertebrae fuse to form the coccyx.
  • Which vertebrae provide attachment points for ribs?
    The thoracic vertebrae provide attachment points for ribs.
  • Which vertebrae support most of the body’s weight?
    The lumbar vertebrae support most of the body’s weight.
  • What movements does the vertebral column allow?
    The vertebral column allows flexible movements such as bending and twisting.
  • What does the vertebral column protect?
    It protects the spinal cord.
  • What is the function of the vertebral column in relation to the head?
    It supports the head and allows its movement.
  • What bones connect the spine to the pelvis?
    The sacrum connects the spine to the hip bones (pelvis).
