Example Questions

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.

Example Question #71 : Bones

Which two bones make up the lower leg, commonly known as the shin?

Possible Answers:

Radius and ulna

Tibia and fibula

Patella and tibia

Fibia and tibula

Femur and tibia

Correct answer:

Tibia and fibula

Explanation:

The tibia and fibula are the two main lower leg bones, and make up the "shin". The femur is the thigh bone, located proximal to the lower leg. The patella is commonly known as the "knee cap" and does not make up the bones of the lower leg in this question. Be careful not to make the common spelling errors: tibula and fibia are not real structures.

Example Question #72 : Bones

All of these muscles flex the leg at the knee joint and extend the thigh at the hip joint except __________

Possible Answers:

tensor fasciae latae muscle

semimembranosus muscle

semitendinosus muscle

hamstring muscles

biceps femoris muscle

Correct answer:

tensor fasciae latae muscle

Explanation:

The "hamstring" muscles consist of the biceps femoris, semitendinosus, and semimembranosus all of which are flexors of the leg at the knee joint and extensors of the thigh at the hip joint. The tensor fasciae latae muscle is involved in stabilizing the pelvic girdle while walking or running.

Example Question #76 : Bones

The __________ are the seven bones that make up the ankle.

Possible Answers:

tarsals

metacarpals

metatarsals

carpals

Correct answer:

tarsals

Explanation:

The tarsals are the seven bones that make up the ankle. The metatarsals are analogous to the metacarpals of the hand and make up the body of the foot. The carpals are the eight wrist bones. The metacarpals make up the body of the hand.

Example Question #77 : Bones

The __________ make up the body of the foot.

Possible Answers:

tarsals

carpals

metatarsals

metacarpals

Correct answer:

metatarsals

Explanation:

The metatarsals are analogous to the metacarpals of the hand and make up the body of the foot. The tarsals are the seven bones that make up the ankle. The carpals and metacarpals make up the wrist and body of the hand, respectively.

Example Question #78 : Bones

The __________ are the bones of the fingers and toes.

Possible Answers:

tarsals

carpals

metatarsals

phalanges

Correct answer:

phalanges

Explanation:

The phalanges are the bones of the fingers and toes. The carpals make up the wrist. The tarsals and metatarsals make up the ankle and the body of the foot, respectively.

Example Question #1 : Identifying Bones Of The Upper Extremities

Which of the following is not found on the scapula?

Possible Answers:

Glenoid fossa

Coracoid process

Acromial process

Supraspinous fossa

Coronoid process

Correct answer:

Coronoid process

Explanation:

The scapula is located posterior to the ribs and is used in the shoulder joint to house the head of the humerus and the acromion of the clavicle.

The acromion of the clavicle interfaces with the acromion process, while the head of the humerus interfaces with the glenoid fossa. The coracoacromial ligament runs between the acromion process and coracoid process and serves to stabilize and protect the muscles of the shoulder. Damage to this ligament results in a separated shoulder. The supraspinous fossa is located on the posterior of the scapula and serves as the point of origin for the supraspinatus muscle.

The coronoid process is found on the ulna and interfaces with the coronoid fossa of the humerus in the elbow. Damage or dislocation of the elbow can cause the coronoid process to fracture.

Example Question #1 : Identifying Bones Of The Upper Extremities

Which of the following is located adjacent to the hamate?

Possible Answers:

Scaphoid

First metacarpal

Capitate

Navicular

Cuboid

Correct answer:

Capitate

Explanation:

The hamate is one of the carpals, located in the wrist. There are eight carpal bones, roughly organized into two rows. The triquetral, lunate, and scaphoid are aligned in a row from medial to lateral at the interface of the carpals with the ulna and radius. The pisiform is located anterior to the triquetral and occupies a slightly different plane than the other carpals. Distal to the row formed by the triquetral, lunate, and scaphoid are the remaining carpals: the hamate, capitate, trapezoid, and trapezium (ordered medial to lateral).

The cuboid and navicular are tarsal bones, located in the ankle and foot.
