Explanation / Answer

Answers:

Sulcus

Bony landmark: Costal Groove/ sulcus costae

Location: Situated at the inner surface along the inferior border of the rib, this groove contains the posterior intercostal vessels

Suture:

Bony landmark : Coronal suture

Location: Placed between the frontal bone and the two parietal bones of the skull. The suture crosses the cranial vault from one side to another.

Foramen

1) Bony landmark: Foramen Magnum

Location: Largest foramen of the skull. It is located in the posterior cranial fossa and faces downwards into the vertebral canal. It transmits the lower part of the medulla which continues as the spinal cord in the vertebral canal.

2) Bony Landmark: Foramen Transversaria.

Location: Located on the transverse processes of the cervical vertebrae; it transmits the vertebral artery.

Fissure

Bony landmark: Superior orbital fissure

Location: The superior orbital fissure is located within the bony orbit of the skull bounded medially by the body of the sphenoid, laterally by the frontal bone, superiorly by the lesser wing of the sphenoid and inferiorly by the greater wing of the sphenoid.

2) Bony landmark: Inferior orbital fissure

Location: Located on the orbital floor, bounded superiorly by the greater wing of the sphenoid, inferiorly by the maxilla and the orbital process of the palatine bone and laterally by the zygomatic bone.
