On which bone do we find the mastoid process?
Occipital.
Sphenoid.
Frontal.
Temporal.
The Correct Answer is D
The mastoid process is a bony projection of the temporal bone at the posterior base of the skull.
It allows the attachment of muscles such as the sternocleidomastoid and splenius capitis.
It also contains air-filled spaces called the mastoid air cells.
Choice A is incorrect because the occipital bone forms the back and base of the skull and does not have a mastoid process.
Choice B is incorrect because the sphenoid bone is a butterfly-shaped bone at the base of the skull that does not have a mastoid process.
Choice C is incorrect because the frontal bone forms the forehead and the upper part of the eye sockets and does not have a mastoid process.

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.
Correct Answer is ["Ulna bone"]
Explanation
The ulna is one of the two bones of the forearm, located on the medial (inner) side of the arm.
It is a long bone that runs parallel to the radius bone, extending from the elbow joint to the wrist joint.
The ulna features several surface landmarks, including the olecranon process, which forms the bony tip of the elbow.
The bone is also involved in the formation of the elbow joint, where it articulates with the humerus bone, and the wrist joint, where it articulates with the radius bone and several carpal bones.
The ulna is an important site for the attachment of muscles involved in forearm and wrist movements.
