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 ["Radial flexion of the wrist"]
Explanation
Radial flexion of the wrist, also known as radial deviation, refers to the movement of the wrist towards the radial (thumb) side of the forearm.
This movement is achieved by the contraction of muscles on the lateral (thumb) side of the forearm.
The joint involved in radial flexion of the wrist is the radiocarpal joint, which is a condyloid joint formed by the articulation between the distal end of the radius bone and the carpal bones of the wrist.
This joint allows for a range of movements, including:
1. Ulnar flexion of the wrist: This refers to the movement of the wrist towards the ulnar (little finger) side of the forearm, which is achieved by the contraction of muscles on the medial (little finger) side of the forearm.
2. Extension of the wrist: This refers to the movement of the wrist backward, away from the palm of the hand.
This movement is achieved by the contraction of muscles on the back of the forearm.
3. Flexion of the wrist: This refers to the movement of the wrist forwards, towards the palm of the hand.
This movement is achieved by the contraction of muscles on the front of the forearm.
4. Adduction of the wrist: This refers to the movement of the wrist towards the midline of the body, which is achieved by the contraction of muscles on the medial (little finger) side of the forearm.
5. Abduction of the wrist: This refers to the movement of the wrist away from the midline of the body, towards the radial (thumb) side of the forearm, which is achieved by the contraction of muscles on the lateral (thumb) side of the forearm.
All of these movements of the radiocarpal joint are important for fine motor skills, such as writing, typing, and playing musical instruments, as well as for everyday activities such as lifting and carrying objects.
Correct Answer is ["Intercondylar eminence of the tibia"]
Explanation
The intercondylar eminence of the tibia is a prominent bony ridge located on the superior aspect of the tibial plateau, which is the top surface of the tibia bone that articulates with the femur.
The eminence separates the two condyles of the tibia and serves as an attachment site for several ligaments, including the anterior and posterior cruciate ligaments of the knee joint.
These ligaments play a critical role in stabilizing the knee joint and preventing excessive forward or backward movement of the tibia relative to the femur.
The intercondylar eminence also provides a surface for the menisci, which are C- shaped fibrocartilaginous structures that help absorb shock and distribute forces in the knee joint.
