Identifying Bones of the Upper Extremities - Anatomy

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.

The olecranon is a feature of the ulna. It is commonly known as the elbow. The coracoid process can be found on the scapula and both the deltoid tuberosity and trochlea can be found on the humerus.

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.

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.

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.

The shoulder girdle (or what bones keep the arm attached the the body) is made up of the clavicle and scapula, which together create the frame for the joint space for the upper arm, as well as muscle attachment.

The clavicle is commonly known as the collar bone. Hint: the collar of your shirt lies against this bone.

The humerus makes up the upper arm. The clavicle and scapula create the shoulder girdle in which the humerus joins with. Finally the radius and Ulna make up the forearm bones.

The radius and ulna make up the forearm bones, which meet with the humerus of the upper arm to create the elbow joint. All other options only include one or some of these bones, which make them incorrect.

The carpals make up the wrist. The metacarpals make up the body of the hand. The tarsals and metatarsals make up the ankle and the body of the foot, respectively.

The metacarpals make up the body of the hand. The carpals make up the wrist. The tarsals and metatarsals make up the ankle and the body of the foot, respectively.

The humerus is the largest, longest bone of the upper limb. The radius and ulna — neither as large as the humerus — make up the forearm, while the femur is analogous to the humerus in the lower limb.

Phalanges, the digits of the hand, are the most distal bones of the upper limb.

The humerus is the bone of the upper arm. The ulna is the bone of the medial side of the forearm. The radius is the bone of the lateral side of the forearm. These bones are all proximal to the phalanges.

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.

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.

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.

An AB positive patient is known as a universal recipient because they can receive blood from any blood type. The recipient's antibodies are what will attack foreign antigens. Type AB positive patients produce no antibodies, because any antibody produced would attack their own antigens, causing agglutination. Because type AB patients patients do not produce antibodies, they cannot attack any antigens and they can receive any blood type.

The forearm has two bones: the radius and the ulna. In order to determine which forearm bone is medial to the body, we need to remember standard anatomical position. In this position, the palms face outward, meaning the pinky is the closest finger to the body. The ulna is on the side of the pinky, while the radius is on the side of the thumb. As a result, the ulna is the forearm bone medial to the body.

The humerus is located proximal to the radius and ulna and forms the shoulder joint with the scapula. The clavicle is superior to the humerus and articulates with the scapula above the shoulder.

The humerus articulates with the scapula, making the glenohumeral joint at the head, and the radius and ulna, making the elbow joint at the trochlea. The anatomic neck is the area immediately below the head that functions as attachment for the joint capsule of the glenohumeral joint. The spiral groove houses the radial nerve and serves as an attachment site for the lateral and medial head of the biceps brachii.

The surgical neck is located between the anatomical neck and shaft of the humerus, marking a narrower region of the bone. The surgical neck is the most common site of fracture on the humerus. The axillary nerve and the posterior humeral circumflex artery also course through this region and can be damaged in the case of injury.
