Questions: Which of the following bones are found within the axial skeleton? Multiple Choice The radius, ulna, carpals, and phalanges The upper and lower limbs and pelvic and pectoral girdles The femur, tibia, and fibula The skull, hyoid bone, thoracic cage, and vertebral column

The answer is the fourth one: the skull, hyoid bone, thoracic cage, and vertebral column.

Explanation for each option:

• The radius, ulna, carpals, and phalanges: These bones are part of the appendicular skeleton, specifically the bones of the upper limbs.

• The upper and lower limbs and pelvic and pectoral girdles: These are all components of the appendicular skeleton, which includes the limbs and girdles that attach them to the axial skeleton.

• The femur, tibia, and fibula: These bones are part of the appendicular skeleton, specifically the bones of the lower limbs.

• The skull, hyoid bone, thoracic cage, and vertebral column: These are all part of the axial skeleton, which includes the central core of the body and supports and protects the organs of the head, neck, and trunk.

In summary, the axial skeleton consists of the skull, hyoid bone, thoracic cage, and vertebral column, making the fourth option the correct answer.
