  • What are the main components of the skeleton?
    The skeleton is composed mostly of bones, with some cartilage and ligaments.
  • What are the two major divisions of the skeleton?
    The skeleton is divided into the Axial Skeleton and the Appendicular Skeleton.
  • What bones make up the axial skeleton?
    The axial skeleton includes the skull, vertebral column, and thoracic cage.
  • Name the major bones of the skull visible from the anterior view.
    Frontal bone, nasal bones, maxilla, mandible, zygomatic bones, and orbit structures.
  • What is the function of sutures in the skull?
    Sutures are immovable joints that connect the bones of the skull, such as the coronal, sagittal, squamous, and lambdoid sutures.
  • What are the key features of a typical vertebra?
    A vertebra has a body, vertebral foramen, spinous process, transverse processes, and articular processes.
  • How many vertebrae are in each region of the vertebral column?
    7 cervical, 12 thoracic, 5 lumbar, fused sacrum, and fused coccyx vertebrae.
  • What is the function of the intervertebral discs?
    Intervertebral discs act as shock absorbers and allow slight movement between vertebrae.
  • What bones form the thoracic cage?
    The thoracic cage consists of the sternum, ribs, and thoracic vertebrae.
  • What are the three parts of the sternum?
    The sternum is composed of the manubrium, body, and xiphoid process.
  • What bones make up the shoulder girdle?
    The shoulder girdle consists of the clavicle and scapula.
  • Name the major landmarks of the scapula.
    Acromion, coracoid process, spine, glenoid cavity, supraspinous fossa, and infraspinous fossa.
  • What are the main bones of the arm?
    The humerus in the upper arm, and the radius and ulna in the forearm.
  • What bones form the pelvic girdle?
    The pelvic girdle is formed by two hip bones, each consisting of the ilium, ischium, and pubis.
  • What is the acetabulum?
    The acetabulum is the deep socket on the hip bone that articulates with the head of the femur.
  • Name the major bones of the leg.
    The femur, patella, tibia, and fibula.
  • What bones make up the foot?
    Tarsals, metatarsals, and phalanges.
  • What is the function of the vertebral foramen?
    The vertebral foramen forms the vertebral canal through which the spinal cord passes.
  • What is the difference between true ribs and false ribs?
    True ribs attach directly to the sternum; false ribs attach indirectly or not at all.
  • What is the significance of the foramen magnum?
    The foramen magnum is the large opening in the occipital bone where the spinal cord connects to the brain.
