  • What is the primary function of the appendicular skeleton?
    The appendicular skeleton is involved in changing your position in the external environment, such as standing, walking, sitting, dressing, and driving.
  • What bones make up the pectoral girdle?
    The pectoral girdle includes the S-shaped clavicle (collarbone) and the flattened scapula (shoulder blade).
  • How does the clavicle connect to the axial skeleton?
    The clavicle articulates with the manubrium of the sternum and is the only direct connection between the axial skeleton and the pectoral girdle.
  • Does the scapula have a direct connection to the axial skeleton?
    No, the scapula is attached to the clavicle anteriorly but has no direct connection to the axial skeleton; it is supported by skeletal muscles and ligaments.
  • What bones compose the upper limb?
    The upper limb consists of the brachium (humerus), antebrachium (ulna and radius), wrist (carpals), and hand (metacarpals and phalanges).
  • How many carpal bones are in the wrist?
    There are 8 carpal bones in the wrist.
  • What bones make up the palm of the hand?
    The 5 metacarpal bones articulate with the distal carpal bones to form the palm of the hand.
  • How many phalanges are in the hand?
    The hand contains 14 phalanges, which make up the finger bones.
  • What is the pelvic girdle composed of?
    The pelvic girdle consists of two ossa coxae bones.
  • What are the main functions of the pelvic girdle?
    The pelvic girdle supports and protects the lower viscera and the developing fetus in females.
  • How do the bones of the pelvic girdle and lower limb compare to those of the upper limb?
    The bones of the pelvic girdle and lower limb are much more massive than their homologues in the upper limb.
  • List some differences between the male and female pelvis.
    The female pelvis has an enlarged pelvic outlet, less curvature of the sacrum and coccyx, a wider and more circular pelvic inlet, a broader and lower pelvis, widely fanning ilia, and a pubic angle greater than 100 degrees.
  • What bones make up the lower limb?
    The lower limb consists of the femur (thigh), patella (kneecap), tibia and fibula (leg), tarsal bones of the ankle, metatarsal bones, and phalanges of the foot.
  • How many tarsal bones are in the ankle?
    There are 7 tarsal bones that make up the ankle.
  • What bones form the arches of the foot?
    The 5 metatarsal bones articulate with the distal tarsal bones to form the arches of the foot.
  • How many phalanges are in the foot?
    The foot contains 14 phalanges, which make up the toe bones.
  • What types of personal information can your skeleton reveal?
    Your skeleton can reveal your race, medical history, gender, body size, muscle mass, and age.
  • What changes occur in the skeletal system as you age?
    As you age, a number of changes and events take place in the skeletal system, including bone density loss and structural changes.
