Explanation / Answer

4)

The mandible contains condyloid process that is thicker than coronoidprocess. It contains 2 parts : condyle and the neck. Condyloid process is the articular. Coronoid process is triangular eminence and extends from side to side and is flat. It is for the muscle attachment. Option c is correct.

1)

Girdles are part of appendicular skeleton and attach the appendages (upper and lower limbs) to the axial skeleton. Option c is correct.

2)

The frontal bone is one of eight bones that form the cranium, or brain case and forms the forehead. It contributes to the sagittal suture. Option a is correct.

3)

The ethmoid bone does not contain Olfactory foramina. Option a is correct.

4)

The mandible has condylar processes and coronoid processes. The condylar process is articular; the coronoid process is for muscle attachment. Option c is correct.

5)

Paranasal sinuses are paired and occur as 4 pairs. They are maxillary sinuses, frontal sinuses, ethmoidal sinuses and sphenoidal sinuses. False about paranasal sinuses is they are located in zygomatic bone. Option c is correct.

6)

A pair of skull bones contributes to the only freely movable joint of the head are temporal and mandible. Option a is correct.

7)

Ethmoid bone contains the foramina for passage of branches of the trigeminal (V) nerve. Option a is correct.

8)

Transverse process does not surround the spinal cord to keep it protected from injury. It is attached to muscles and ligaments. Option d is correct.
