  • What is the appendicular skeleton?
    The appendicular skeleton includes the bones of the limbs and the girdles that attach them to the axial skeleton.
  • Which bones make up the pectoral girdle?
    The pectoral girdle consists of the clavicles and scapulae.
  • What is the function of the pectoral girdle?
    It connects the upper limbs to the axial skeleton and provides attachment points for muscles.
  • Name the bones of the upper limb.
    The upper limb includes the humerus, radius, ulna, carpals, metacarpals, and phalanges.
  • What bone articulates with the scapula at the shoulder joint?
    The humerus articulates with the scapula at the shoulder joint.
  • Which bones form the pelvic girdle?
    The pelvic girdle is formed by two hip bones (coxal bones), each made of the ilium, ischium, and pubis.
  • What is the main function of the pelvic girdle?
    It supports the weight of the body and protects pelvic organs.
  • Name the bones of the lower limb.
    The lower limb includes the femur, patella, tibia, fibula, tarsals, metatarsals, and phalanges.
  • Which bone is the longest in the human body?
    The femur is the longest bone in the human body.
  • What is the role of the patella?
    The patella protects the knee joint and improves leverage for thigh muscles.
  • Which bones form the ankle joint?
    The tibia, fibula, and talus form the ankle joint.
  • How many bones are in the appendicular skeleton?
    There are 126 bones in the appendicular skeleton.
  • What is the difference between the radius and ulna?
    The radius is on the thumb side and rotates around the ulna, which is on the pinky side.
  • Which bone bears most of the weight in the lower leg?
    The tibia bears most of the weight in the lower leg.
  • What bones make up the wrist?
    The wrist is made up of eight carpal bones.
  • What bones make up the ankle?
    The ankle is made up of seven tarsal bones.
  • What is the function of the metacarpals and metatarsals?
    They form the framework of the palm of the hand and the sole of the foot.
  • How many phalanges are in each hand and foot?
    Each hand and foot has 14 phalanges.
  • What is the role of the ischium in the pelvic girdle?
    The ischium supports body weight when sitting.
  • Which part of the pelvic bone forms the hip socket?
    The acetabulum is the hip socket formed by the ilium, ischium, and pubis.
