Correct Answer is ["Occipital bone"]
Explanation
The occipital bone is a flat, unpaired bone located at the posterior aspect of the skull, forming the lower part of the back of the head.
It features several surface landmarks, including the external occipital protuberance, which serves as an attachment site for muscles and ligaments.
The occipital bone also contains several foramina, including the foramen magnum, which allows the spinal cord to pass through and connect to the brain.
The occipital bone is an important site for the attachment of muscles involved in head movement and posture.
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.
