Upper Extremity - Bones

Question 1

(Hand) Phalanges

Answer 1

the bones of the fingers and toes. Phalanges is the plural form of phalanx. You have 14 phalanges in each hand and in each foot

Question 2

Acromioclavicular joint

Answer 2

Clavicle - where the acromion (part of the shoulder blade/scapula) articulates with the clavicle (collarbone) at the top of the shoulder.

Question 3

Acromion

Answer 3

Scapula - the bony projection that forms the point of the shoulder

Question 4

Anatomical neck

Answer 4

Humerus - a groove on the proximal (upper) end of the humerus (upper arm bone) that separates the head of the humerus from the greater and lesser tubercles

Question 5

Lateral angle of the scapula

Answer 5

scapula - also known as the Glenoid process, the outside corner/edge of the outward facing angle of the scapula’s triangular shape

Question 6

Axillary/Lateral border of the scapula

Answer 6

Scapula - bottom edge of the scapula that extends from the Glenoid fossa to the Inferior angle

Question 7

carpals mnemonic (8)

Answer 7

“She Looks Too Pretty, Try To Catch Her”

(S)he
(L)ooks
(T)oo
(P)retty
(T)ry
(T)o
(C)atch
(H)er

(S)caphoid
(L)unate
(T)riquetrum
(P)isiform
(T)rapezium
(T)rapezoid
(C)apitate
(H)amate

T’s order - (-trum,-zium,-zoid)

This phrase corresponds to the bones in the order they appear in the hand (anterior/supine/anatomical view), starting with the proximal row from the thumb side to the pinky side and then continuing with the distal row from the thumb side to the pinky side. (Read lateral to medial in anatomial position, and bottom to top.)

Question 8

Coracoid process

Answer 8

Scapula - a small, hook-like structure on the scapula (shoulder blade) located on the anterior (front) side of the scapula, just below the clavicle (collarbone) almost under the acromion.

Question 9

Deltoid tuberosity

Answer 9

Humerus - a roughened, V-shaped area on the lateral (outer) side of the humerus approximately one-third of the way down the bone from the shoulder joint.

Question 10

Glenoid fossa/cavity

Answer 10

Scapula - a shallow, pear-shaped socket on the lateral (outer) aspect of the scapula (shoulder blade). It serves as the articulation point for the humeral head (upper arm bone), forming the glenohumeral joint, which is the shoulder joint.

Question 11

Greater tubercle/tuberosity of the Humerus (tuberosity is bigger)

Answer 11

Humerus - a prominent bony projection located on the lateral (outer) side of the humerus’s proximal (upper) end, just below the head of the humerus.

Question 12

Head of the humerus

Answer 12

Humerus - the rounded, superior portion of the upper arm bone (humerus) that articulates with the glenoid cavity of the scapula, forming the glenohumeral joint (shoulder joint)

Question 13

Head of the Radius

Answer 13

Radius -

Question 14

Inferior angle of the scapula

Answer 14

Scapula - the bottom corner of the downward facing angle of the scapula’s triangular shape

Question 15

Lateral epicondyle of the Humerus

Answer 15

a bony prominence located on the outer (lateral) side of the humerus, near the elbow joint (distal end of humerus).

Question 16

Lesser tubercle

Answer 16

Humerus - a bony prominence located on the anterior aspect of the humerus, just below the head.

Smaller than the greater tubercle, but more prominent and directed medially and anteriorly.

Question 17

Medial epicondyle of the Humerus

Answer 17

Humerus - It’s a bony projection on the medial (inner) side of the distal humerus.

Question 18

Metacarpals

Answer 18

the five long bones in the palm of the hand, located between the carpals and phalanges. They are numbered 1 through 5, with the first metacarpal connected to the thumb and the fifth to the little finger.

Each metacarpal has a base, a shaft, and a head, and they articulate with both the carpals and phalanges.

Question 19

Olecranon fossa

Answer 19

Humerus - a deep depression located on the posterior side of the distal humerus.

Function:
The olecranon fossa provides a space for the olecranon process of the ulna (the bony tip of the elbow) to fit into when the elbow is extended.

Question 20

Olecranon process

Answer 20

Ulna - the bony prominence that makes up the “pointy” part of the elbow joint.

Question 21

process vs fossa

Answer 21

a process is a prominent projection or outgrowth on a bone, while a fossa is a shallow depression or hollow in a bone

Question 22

Shaft/Body of the Humerus

Answer 22

Humerus - the long main body of the bone

Question 23

Spine of the scapula

Answer 23

Scapula - runs diagonally across the scapula, starting from the medial border and extending towards the acromion (the bony projection that forms the point of the shoulder).

Also acts as a divider for the posterior surface of the scapula.

Question 24

Radial Styloid process

Answer 24

Radius - a bony projection located at the distal end of the radius bone in the anatomical lateral forearm, near the wrist (the bump on the thumb side of the wrist).

Question 25

Subscapular fossa

Answer 25

Scapula - a broad, concave area on the anterior (costal) surface of the scapula (shoulder blade), serving as the origin for the subscapularis muscle, a key component of the rotator cuff. This fossa is located on the side of the scapula that faces the ribcage

Question 26

Superior/Medial angle of the scapula

Answer 26

scapula - the top corner of the upward facing angle of the scapula's triangular shape

Question 27

Superior border of the scapula

Answer 27

scapula - short, top edge of the scapula

Question 28

Supraspinous and infraspinous fossa

Answer 28

Scapula - (above and below the spine of the scapula) the two shallow and wide depressions that make up the backside/posterior of the scapula. The infraspinous fossa is much larger

Question 29

Surgical neck

Answer 29

Humerus - a specific anatomical location on the upper arm bone (humerus), situated just below the head and tubercles, and is a common site for fractures.

Question 30

Ulnar styloid process

Answer 30

Ulna - a bony projection located at the distal end of the ulna bone in the anatomical medial forearm, near the wrist (the bump on the pinky side of the wrist).

Question 31

Vertebral/Medial border of the scapula

Answer 31

Scapula - the longest edge of the scapula, running parallel to the vertebral column.
