Example Question #21 : Identifying Bones Of The Upper Extremities

Which is the lateral bone of the forearm?

Possible Answers:

Fibula

Radius

Humerus

Ulna

Tibia

Correct answer:

Radius

Explanation:

The radius is the lateral bone of the forearm. The ulna is the medial bone of the forearm; it articulates with the humerus and radius. The humerus is the largest bone of the upper limb and is the only bone of the (upper) arm. The fibula is the lower leg's analog of the radius. Remember to refer to the anatomical position whenever orienting yourself with gross anatomy.

Example Question #22 : Identifying Bones Of The Upper Extremities

Which is the medial bone of the forearm?

Possible Answers:

Tibia

Coxa

Humerus

Radius

Ulna

Correct answer:

Ulna

Explanation:

The ulna is the medial bone of the forearm; it articulates with the humerus and radius. The radius is the lateral bone of the forearm. The humerus is the largest bone of the upper limb and is the only bone of the (upper) arm. The tibia is the lower leg's analog of the ulna.

Example Question #23 : Identifying Bones Of The Upper Extremities

The __________ are the eight wrist bones.

Possible Answers:

phalanges

carpals

tarsals

metatarsals

metacarpals

Correct answer:

carpals

Explanation:

The carpals are the eight wrist bones. The metacarpals make up the body of the hand between the wrist and the projection of the fingers. The phalanges are the bones of the fingers and toes. The fourteen tarsals and ten metatarsals make up the ankles and the bodies of the feet, respectively.

The correct answer is the humerus. The greater tubercle is on the superolateral portion of the humerus. The radius and ulna is in the lower portion of the arm. The scaphoid is in the wrist. The femur is in the upper portion of the leg.

Example Question #25 : Identifying Bones Of The Upper Extremities

On which bone is the lesser tubercle?

Possible Answers:

Ulna

Humerus

Ischium

Radius

The correct answer is the humerus. The patella is the knee cap. The ischium is in the pelvis. The radius and ulna is in the lower arm.

Example Question #25 : Identifying Bones Of The Upper Extremities

On which bone is the olecranon process?

Possible Answers:

Scaphoid

Tibia

Humerus

Ulna

Radius

Correct answer:

Ulna

Explanation:

The correct answer is the ulna. The olecranon process is located on the ulna. The olecranon process is not on the radius which is the other bone in the forearm. The humerus is located in the upper portion of the arm. The scaphoid is in the wrist. The tibia is in the lower leg.

Example Question #26 : Identifying Bones Of The Upper Extremities

On which bone is the deltoid tuberosity?

Possible Answers:

Ulna

Clavicle 

Scapula

Humerus

Radius

Correct answer:

Humerus

Explanation:

The deltoid is a muscle on the lateral portion of the upper arm. The humerus is the bone on the upper arm and the deltoid attaches to the humerus. The radius and ulna is located on the lower portion of the arm. The clavicle is in the upper chest, also known as the collarbone. The scapula is the shoulder blade and the deltoid does not attach to it.
