What is one example of a cartilaginous joint?
Hyaline Cartilage joints in the maxilla.
None.
Fibrous Cartilage joints in the Skull.
Hyaline Cartilage joints in the ribs.
The Correct Answer is D
A cartilaginous joint is a joint where the bones are united by cartilage.
A hyaline cartilage joint is a type of cartilaginous joint where the bones are joined by hyaline cartilage.
An example of a hyaline cartilage joint is the first sternocostal joint that unites the first rib to the sternum.
Choice A is incorrect because hyaline cartilage joints are not present in the maxilla.
The maxilla is a single bone that forms the upper jaw and palate. Choice B is incorrect because none is not a valid answer.
Choice C is incorrect because fibrous cartilage joints are not present in the skull. The skull bones are joined by fibrous joints called sutures.

Correct Answer is ["Acetabulum"]
Explanation
acetabulum is the concave cavity located on the lateral surface of the hip bone.
It is formed by the fusion of the ilium, ischium, and pubis bones.
The acetabulum articulates with the head of the femur to form the hip joint, which is a ball-and-socket joint that allows for a wide range of movement.
The acetabulum is lined with articular cartilage, which provides a smooth surface for the head of the femur to move against.
The acetabulum is also surrounded by a fibrocartilaginous ring called the acetabular labrum, which deepens the socket and helps to stabilize the hip joint.
Injuries to the acetabulum can result in hip dislocations or fractures, which can be very painful and require medical intervention.
Correct Answer is ["obturator foramen"]
Explanation
The obturator foramen is a large opening in the pelvis that is formed by the ischium and pubis bones.
It is located in the lower part of the pelvis, below the acetabulum (the socket of the hip joint).
The obturator foramen is covered by the obturator membrane, which separates the pelvic cavity from the thigh.
Several important structures pass through or around the obturator foramen, including the obturator nerve, artery, and vein.
Injuries to the obturator nerve can result in weakness or paralysis of the muscles of the inner thigh, while injuries to the obturator artery and vein can result in severe bleeding and require immediate medical attention.
