Which of the following sinuses is in high risk of infection spreading from the middle ear?
The mastoid sinuses are in high risk of infection spreading from the middle ear.
Where is the single point of attachment of the pectoral girdle to the axial skeleton?
The pectoral girdle attaches to the sternal manubruim of the axial skeleton via the medial end of its clavicle.
What is the sternal angle and what is its clinical importance?
The sternal angle is a ridge across the front of the sternum where the manubrium joins the sternal body. It acts as a hinge allowing the sternum to swing anteriorly when we inhale. Because it is aligned with the second rib, it is a handy cue for finding that rib and then counting the ribs during a physical exam.
Which of the following cranial bones receive the condyle of the mandible?
The temporal bone contains the mandibular fossa that receives the condyle of the mandible and forms the temporomandibular joint.
