Question 1

Which of the following bones contains a diaphysis?&#10;A) patella&#10;B) carpal&#10;C) sternum&#10;D) tibia

Accepted Answer

The tibia is a long bone in the leg that contains a diaphysis, which is the long, cylindrical shaft of the bone. The patella is a sesamoid bone, the carpal bones are short bones, and the sternum is a flat bone, and none of these contain a diaphysis.

Question 2

The optic canal is found in which of the following bones?&#10;A) sphenoid&#10;B) maxilla&#10;C) frontal&#10;D) lacrimal

Accepted Answer

The optic canal is a bony passageway located in the sphenoid bone of the skull. It allows the optic nerve, which carries visual information from the retina to the brain, to pass from the eye to the brain. The other options, maxilla, frontal, and lacrimal, do not contain the optic canal.

Question 3

Which bone contains the supraorbital foramen?&#10;A) maxilla&#10;B) ethmoid&#10;C) frontal&#10;D) palatine

Accepted Answer

The supraorbital foramen is located in the frontal bone, specifically in its superciliary arch. The maxilla, ethmoid, and palatine bones do not contain this structure.

Question 4

Which of the following bones belongs in the axial skeleton?&#10;A) clavicle&#10;B) phalanges&#10;C) fibula&#10;D) sternum

Accepted Answer

The sternum is part of the axial skeleton which includes the bones of the skull, vertebral column, and rib cage. The clavicle and fibula are part of the appendicular skeleton which includes the bones of the limbs and their girdles. The phalanges are also part of the appendicular skeleton, specifically the bones of the fingers and toes.

Question 5

The interconnecting bony struts of spongy bone are known as ________.&#10;A) Haversian canals&#10;B) perforating canals&#10;C) lacunae&#10;D) trabeculae
