Example Questions

Example Question #13 : Identifying Bones Of The Upper Extremities

What part of the humerus can be felt through the skin on the side of the elbow closest to the trunk and is sometimes referred to as the funny bone?

Possible Answers:

Medial tubercle

Medial condyle

Lateral epicondyle

Lateral condyle

Medial epicondyle

Correct answer:

Medial epicondyle

Explanation:

Condyles articulate with bones (such as the lateral and medial condyles of the femur) while epicondyles serve as attachment points for ligaments and muscles. The funny bone is the medial epicondyle. Lateral refers to something farther from the mid line. The ulnar nerve passes between the medial epicondyle and the olecranon process of the ulna, so it can easily be overstimulated by being hit on one of these bony prominences.

Example Question #302 : Human Anatomy And Physiology

Which of the following bones can be found in the shoulder girdle?

Possible Answers:

Femur

Scapula

Ulna

Sternum

Humerus

Correct answer:

Scapula

Explanation:

Anatomically speaking, the shoulder girdle in humans consists of two bones: the scapula and the clavicle. Of the answer choices listed, scapula is the only one that is correct.

Example Question #14 : Identifying Bones Of The Upper Extremities

Which bones of the upper body have an interosseous membrane between them?

Possible Answers:

Ribs

Tibia and fibula

Clavicle and scapula

Sternum and ribs

Ulna and radius

Correct answer:

Ulna and radius

Explanation:

Interosseous membranes are thin flat stretches of fibrous tissue that stretch between the ulna and radius of the forearm and also between the tibia and fibula of the lower limbs. They serve to separate structures such as the muscles on the anterior and posterior sides of the arm, absorb impact, and maintain integrity of the joint during movements.

Example Question #15 : Identifying Bones Of The Upper Extremities

What is the anatomical name for the point of your elbow?

Possible Answers:

Olecranon of the ulna

Olecranon of the radius

Lateral condyle of the ulna

Medial condyle of the ulna

Correct answer:

Olecranon of the ulna

Explanation:

Of the two bones in the forearm, the point of the elbow is located on the ulna. This eliminates the answer choice that says the olecranon of the radius because that is not an actual structure. The medial and lateral condyles are located on either side of the bone, meaning the correct answer is the olecranon of the ulna.

Example Question #305 : Human Anatomy And Physiology

Which of the following carpal bones articulates with the proximal end of the first metacarpal?

Possible Answers:

Trapezoid

Trapezium

Hamate

Scaphoid

Triquetrum

Correct answer:

Trapezium

Explanation:

Distal row of carpals from lateral to medial: trapezium, trapezoid, capitate, hamate. Proximal row of carpals from lateral to medial: scaphoid, lunate, triquetrum, pisiform.

Example Question #301 : Gross Anatomy

Which is the lateral bone of the forearm?

Possible Answers:

Fibula

Ulna

Tibia

Radius

Humerus

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 #96 : Bones

Which is the medial bone of the forearm?

Possible Answers:

Ulna

Radius

Humerus

Coxa

Tibia

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 #302 : Gross Anatomy

The __________ are the eight wrist bones.

Possible Answers:

metatarsals

carpals

tarsals

phalanges

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.

Example Question #308 : Human Anatomy And Physiology

On which bone is the greater tubercle?

Possible Answers:

Radius

Femur

Humerus

Ulna

Scaphoid

Correct answer:

Humerus

Explanation:

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:

Patella

Humerus

Ulna

Radius

Ischium

Correct answer:

Humerus

Explanation:

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.
