Question 1

Which of the following bones contains a diaphysis?
A) patella
B) carpal
C) sternum
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

B) maxilla
C) frontal
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?
A) maxilla
B) ethmoid
C) frontal
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?
A) clavicle
B) phalanges
C) fibula
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 ________.
A) Haversian canals
B) perforating canals
C) lacunae
D) trabeculae

Accepted Answer

Trabeculae are the interconnecting bony struts of spongy bone, while Haversian canals and perforating canals are found in compact bone and lacunae are small cavities in bone tissue where osteocytes reside.

Question 6

In which of the following bones would the diploë be found?
A) parietal
B) sternum
C) femur
D) rib

Accepted Answer

Diploë refers to the spongy bone layer found in the flat bones of the skull, such as the parietal bone. It is not present in the other bones listed.

Question 7

Which of the following bones contains the carotid canal?
A) sphenoid
B) palatine
C) temporal
D) occipital

Accepted Answer

The carotid canal is located in the temporal bone, which allows passage for the internal carotid artery to travel through the skull and into the brain.

Question 8

A doctor informs you that your son has fractured a sesamoid bone.Which of the following is the most likely bone that was fractured?
A) radius
B) scapula
C) patella
D) humerus

Accepted Answer

The patella is the most commonly known sesamoid bone in the body and is located within the tendon of the quadriceps muscle, just below the knee joint. The other options listed are not sesamoid bones.

Question 9

Which of the following changes in the vertebral column is most likely to occur during pregnancy?
A) osteoporosis
B) kyphosis
C) lordosis
D) scoliosis

Accepted Answer

Lordosis, or an increased inward curvature of the lower spine, is common during pregnancy due to the changes in weight distribution and the hormone relaxin softening the ligaments in the pelvic region to prepare for childbirth.

Question 10

A ________ is a round or oval hole or opening in a bone.
A) sinus
B) tuberosity
C) trochlea
D) foramen

Accepted Answer

A foramen is a round or oval opening in a bone that serves as a passage for nerves and blood vessels. Sinuses are air-filled cavities in bones, tuberosity is a bony prominence where tendons and muscles attach, and trochlea is a smooth, grooved articular process shaped like a pulley.

Question 11

A 57-year-old female has recently been diagnosed with overproduction of red bone marrow,which has been causing significant bone pain.Which of the following bones is likely to be involved?
A) tarsals
B) vertebra
C) metacarpals
D) patella

Accepted Answer

Vertebrae are a common site for bone pain in conditions of overproduction of red bone marrow, such as polycythemia vera. Tarsals and metacarpals may also be affected, but are less common sites. The patella is unlikely to be involved in this condition.

Question 12

A five-year-old boy is struck in the head with a baseball.The physician identifies in an MRI that the petrous ridge has shifted superiorly.What bone contains the petrous ridge?
A) temporal
B) occipital
C) frontal
D) sphenoid

Accepted Answer

The petrous ridge is a bony ridge located on the lower portion of the temporal bone. Therefore, the correct answer is A) temporal. The other options are not correct as they do not contain the petrous ridge.

Question 13

Which of the following bones is a component of the hard palate?
A) ethmoid
B) maxilla
C) vomer
D) sella turcica

Accepted Answer

The maxilla bone is a component of the hard palate, along with the palatine bones. The ethmoid bone is part of the cranial cavity and helps form parts of the nasal cavity, while the vomer bone is a component of the nasal septum. The sella turcica is a bony saddle-shaped structure within the sphenoid bone that houses the pituitary gland.

Question 14

Which bone is found within the pelvis?
A) ilium
B) radius
C) tibia
D) humerus

Accepted Answer

The ilium is one of the three bones that make up the pelvis. The radius, tibia, and humerus are not located in the pelvis.

Question 15

What type of bone is the sternum?
A) irregular
B) flat
C) sutural
D) sesamoid

Accepted Answer

The sternum is a flat bone that is located in the center of the chest, connecting the ribs.

Question 16

What histological structure immediately surrounds a central canal in compact bone?
A) osteon
B) lacunae
C) Haversian system
D) bone lamellae

Accepted Answer

Bone lamellae are concentric rings of calcified matrix that immediately surround the central canal in an osteon of compact bone.

Question 17

Which of the following sutures connects the two parietal bones of the skull?
A) lambdoid
B) coronal
C) sagittal
D) squamous

Accepted Answer

The sagittal suture is the fibrous connective tissue joint that connects the two parietal bones of the skull, running from the front of the head to the back down the middle.

Question 18

Tarsal bones belong in which classification?
A) short
B) flat
C) sesamoid
D) sutural

Accepted Answer

Tarsal bones are a group of short bones in the human body, located in the ankle and foot. They include the talus, calcaneus, navicular, cuboid, and three cuneiform bones.

Question 19

A ________ is a slit-like opening.
A) meatus
B) process
C) groove
D) fissure

Accepted Answer

A fissure is a narrow, elongated opening or gap, often slit-like in shape. Meatus and groove are also narrow openings, but they are typically larger and more rounded or curved in shape. A process is a projection or outgrowth from a larger structure, and is not typically a type of opening.

Question 20

Which of the following bones belongs in the appendicular skeleton?
A) sternum
B) metatarsal
C) rib
D) vertebra

Accepted Answer

The metatarsals belong to the appendicular skeleton, which includes the bones of the limbs and girdles (shoulder and hip) that support them. The sternum, rib, and vertebra are all part of the axial skeleton, which includes the bones of the skull, vertebral column, and ribcage.
