Question 1
Which of the following joints is a hinge joint?
Correct Answer:
Interphalangeal
Explanation:
Joints that are hinge joints allow motion in one plane around a single axis, mainly flexion and extension, like a door hinge. The joints between the finger bones fit this description, enabling bending and straightening in one plane. The radiocarpal joint (radius and carpal bones) is a condyloid joint with two axes, supporting flexion/extension plus deviation. The atlantooccipital joint is also ellipsoidal/condyloid, permitting nodding with limited lateral movement. The temporomandibular joint combines hinge movement with gliding, so it isn’t a pure hinge. So, the finger interphalangeal joints are the hinge joints.
Question 2
Why is T10 atypical?
Correct Answer:
Only a full pair of facets, articulates with rib 10
Explanation:
In thoracic vertebrae, rib articulation is carried by costal facets on the body and a transverse facet on the transverse process. Most thoracic vertebrae have two demi-facets on the body that accommodate the head of a rib, working with the vertebra above and below. Tenth thoracic vertebra stands out because its body carries a single, complete costal facet for the tenth rib, rather than the usual pair of demi-facets. This makes the pattern of rib articulation on T10 different from the typical thoracic vertebrae.
Question 3
Costotransverse bar is typically found on which group of vertebrae?
Correct Answer:
Typical cervical vertebrae
Explanation:
The costotransverse bar relates to the point where the rib tubercle articulates with the transverse process. This costotransverse articulation is a feature of typical thoracic vertebrae, which have a transverse costal facet on the transverse process to receive the rib tubercle. Cervical vertebrae lack these transverse costal facets (ribs do not articulate with their transverse processes), lumbar vertebrae have no costal facets, and the sacrum is fused with no direct costal articulations. So, the costotransverse bar is typical of the thoracic vertebrae.
Question 4
Which of the following is NOT a part of the sternum?
Correct Answer:
Transverse Process
Explanation:
The sternum is a single midline chest bone that develops from three parts: the manubrium at the top, the body in the middle, and the xiphoid process at the bottom. The manubrium connects with the clavicles and the first two ribs, the body bears facets for ribs 2–7, and the xiphoid process is the small tip at the bottom. The transverse process, on the other hand, is a projection of a vertebra in the spinal column and does not belong to the sternum. It’s a feature of the vertebral arch, not a part of the chest midline bone. So the item that is not part of the sternum is the transverse process.
Question 5
The sternoclavicular joints are best described as which term?
Correct Answer:
Saddle
Explanation:
The shape of the joint surfaces defines its movement. The sternoclavicular joint has saddle-shaped articular surfaces, with one surface convex in one direction and concave in the other, allowing movement in two planes (lifting–lowering and sliding forward–backward) and a bit of rotation as the shoulder moves. This makes it best described as a saddle joint. Synovial is a broader category, and while the joint is synovial, the most specific term is saddle. Sellar is just another word for saddle, but “saddle” is the standard term used.
