An athlete comes into the hospital saying he was informed by the athletic trainer that he broke a bone in his appendicular skeleton.
Which of the following bones could he have broken?
Mandible.
Radius.
Sternum.
Sacrum.
The Correct Answer is B
The radius is a part of the upper limb, which is supported by the pectoral girdle.
The pectoral girdle and the pelvic girdle, along with the bones of the limbs, form the appendicular skeleton.
Choice A is incorrect because the mandible is a part of the skull, which forms the axial skeleton.
Choice C is incorrect because the sternum is a part of the thorax, which forms the axial skeleton.
Choice D is incorrect because the sacrum is a part of the vertebral column, which forms the axial skeleton.

Correct Answer is A
Explanation
The cervical vertebrae are the only vertebrae that have transverse foramina, which are openings in the transverse processes that allow the passage of the vertebral arteries and veins.
Choice B is incorrect because lumbar vertebrae do not have transverse foramina.
They have large bodies and short, thick transverse processes that serve as attachment sites for muscles.
Choice C is incorrect because thoracic vertebrae do not have transverse foramina.
They have costal facets on their transverse processes that articulate with the tubercles of the ribs.
Choice D is incorrect because sacral vertebrae do not have transverse foramina.
They are fused together to form the sacrum, which has four pairs of sacral foramina on each side that transmit sacral nerves and vessels.
Correct Answer is ["epiphyseal analysis"]
Explanation
The epiphysis is the rounded end of the femur that articulates with the hip bone and knee joint.
As a child grows, the epiphysis gradually fuses with the rest of the bone through a process called ossification.
By examining the degree of fusion of the epiphysis with the femur on an X-ray, doctors can estimate the age of the child.
In general, the younger the child, the less fused the epiphysis will be, and the easier it will be to determine the child's age.
However, it's important to note that this method provides only an approximate age range and cannot be used to determine an exact age.
