Example Questions

Example Question #271 : Gross Anatomy

In long bones, where is articular cartilage found?

Possible Answers:

Under the periosteum 

At the ends of bones

Surrounding the entire bone

At growth plates

Correct answer:

At the ends of bones

Explanation:

Long bones have a body that is longer than it is wide (such as the femur, humerus, and phalanges), with growth plates (epiphysis) at either end. The have a hard outer surface of compact bone and a spongy interior known as cancellous bone (contains bone marrow). Both ends of the bone are covered in hyaline cartilage to help protect the bone and decrease friction.

Example Question #272 : Human Anatomy And Physiology

What bone strikes the ground first in a person's normal walking gait?

Possible Answers:

Calcaneus

Cuboid

Navicular

First cuneiform

Talus

Correct answer:

Calcaneus

Explanation:

The calcaneus is the heel bone and generally strikes the ground first in a normal walking gate. It is the most posterior bone in the foot. The achilles tendon attaches to it posteriorly.

Example Question #16 : Identifying Bones Of The Lower Extremities

Which of these bony landmarks are not found in the lower extremity?

Possible Answers:

Soleal line

Lateral supracondylar line

Popliteal fossa

Subclavian groove

Correct answer:

Subclavian groove

Explanation:

The popliteal fossa is part of the femur. The lateral supracondylar line is also part of the femur. The soleal line is part of the tibia. The the subclavian groove is part of the clavicle and is an attachment site for the subclavius muscle.

Example Question #16 : Identifying Bones Of The Lower Extremities

With which of the following does the third cuneiform not articulate?

Possible Answers:

Fifth metatarsal

Second cuneiform 

Third metatarsal 

Navicular

Cuboid

Correct answer:

Fifth metatarsal

Explanation:

The third cuneiform articulates with the navicular, second cuneiform, cuboid, and second, third, and fourth metatarsals.

Example Question #272 : Gross Anatomy

Which of the following landmarks is not part of the femur?

Possible Answers:

Gluteal tuberosity

Soleal line

Adductor tubercle

Linea aspera

Correct answer:

Soleal line

Explanation:

The linea aspera, gluteal tuberosity, and adductor tubercle are all landmarks found on the femur. The linea aspera is an attachment site for the adductor muscle group and the vastus medialis and vastus lateralis. A portion of the gluteus maximus attaches to the gluteal tuberosity. The adductor magnus attaches to the adductor tubercle. The soleal line is part of the tibia and serves as an attachment site for the soleus muscle.

Example Question #273 : Gross Anatomy

The __________ make up the body of the hand between the wrist and the projection of the fingers.

Possible Answers:

carpals

phalanges

metcarpals

metatarsals

tarsals

Correct answer:

metcarpals

Explanation:

The metacarpals are analogous to the metatarsals of the foot and make up the body of the hand between the wrist and the projection of the fingers. The carpals are the eight wrist bones. The tarsals and metatarsals make up the ankle and the body of the foot, respectively. The phalanges are the bones of the fingers and toes.

Example Question #274 : Gross Anatomy

Which of the following anatomical relationships is correct?

Possible Answers:

The scapula is located anteriorly to the clavicle.

The manubrium is located inferiorly to the sternum.

The calcaneus is located proximally to the fibula.

The fibula is located laterally to the tibia.

The femur is located distally to the tibia.

Correct answer:

The fibula is located laterally to the tibia.

Explanation:

The only correct statement in the answer choices is "The fibula is located laterally to the tibia."

The other statements are incorrect for the following reasons:

1) The femur is located distally to the tibia.

The femur is located proximally to the tibia, not distally.

2) The scapula is located anteriorly to the clavicle.

The scapula is located posteriorly to the clavicle, not anteriorly.

3) The calcaneus is located proximally to the fibula.

The calcaneus is located distally to the fibula, not proximally.

4) The manubrium is located inferiorly to the sternum.

The manubrium is located superiorly to the sternum, not inferiorly.

Example Question #71 : Bones

The medial malleolus is part of which bone?

Possible Answers:

Femur

Calcaneus

Tibia

Talus

Fibula

Correct answer:

Tibia

Explanation:

The medial malleolus is located on the inferiomedial aspect of the tibia. The fibula is on the lateral aspect of the lower limb. The talus and calcaneus are in the foot. The femur is in the upper portion of the leg.

Example Question #72 : Bones

On which bone is the greater trochanter?

Possible Answers:

Scapula

Femur

Fibula

Tibia

Humerus

Correct answer:

Femur

Explanation:

The correct answer is the femur. The greater trochanter is located on the superolateral aspect of the femur. The tibia and fibula is in the lower leg. The humerus is in the upper portion of the arm. The scapula is the "shoulder blade."

Example Question #73 : Bones

On which bone is the lesser trochanter?

Possible Answers:

Femur

Scaphoid

Tibia

Sternum

Patella

Correct answer:

Femur

Explanation:

The correct answer is the femur. The lesser trochanter is on the superolateral portion of the femur. The tibia is in the lower leg. The sternum is in the chest. The patella is the knee cap. The scaphoid is in the wrist.
