What is the lesser tubercle of the humerus?
This constricted portion of the humerus is where the head tapers to the diaphysis; located just distal to the tubercles, it gets its name because of it’s propensity for fractures
What is the surgical neck of the humerus ?
This part of the humerus is located on the lateral side, and looks like a round knob and articulates with the head of the radius

This part of the humerus is located on the lateral side, and it curves slightly forward, (anteriorly)
What is the lateral epicondyle of the humerus?
This part of the humerus is located in medially to the capitulum, and looks like a pulley or spool shaped surface, and is known to articulate with the ulna.
What is the trochlea of the humerus?
This part of the humerus is located on the medial side. It is larger and more prominent in the lateral epicondyle, and is directed slightly more posteriorly in the anatomical position.
What is the medial epicondyle of the humerus
This part of the humerus is located on the posterior portion of the humerus, and receives the olecranon process of the ulna when the forearm is extended
What is the olecranon fossa?
This anterior depression of the humerus receives the Coronoid process of the ulna when the forearm is flexed
What is a Coronoid fossa of this humerus?
This is the medial bone of the forearm, which is known to be longer than the radius
What is the ulna?
This forms of prominence, or bump on the elbow and inserts into the olecranon fossa of the humerus, when the forearm is extended
What is the olecranon process of the ulna?
This anterior projection of the ulna inserts into the olecranon fossa of the humerus, when the forearm is flexed
What is the coronoid process of the ulna?
This anterior projection of the ulna articulates with the trochlea of the humerus
What is the coronoid process of the ulna?
This large curved area on the ulna between the olecranon process, and the coronoid process, is described as being half-moon shaped and is considered part of the elbow joint
What is the semi lunar notch a.k.a. the trochlear notch of the ulna.
This part of the ulna articulates with the carpal bones
What is the head of the ulna?
This slender process of the ulna projects from the posterior and medial portion of the ulna for the purpose of muscle attachment and attachment for ligaments of the wrist

What is the right and left radius? 
This part of the radius is disc shaped, and articulates with the capitulum of the humerus
 What is the head of the radius?
This is the constrictive portion of the radius and is located inferior to the head
What is the neck of the radius?
This roughened projection on the medial side of the radius is located just distal to the neck of the bone, and serves as a point of attachment or the biceps brachii muscle
What is the radial tuberosity?
This part of the radius is located on the lateral side, and serves as a point of attachment for muscles of the forearm and ligaments of the wrist
What is the styloid process of the radius?
The proximal portion of the hand is made up of bones known as these
What is the carpus a.k.a. carpal bones of the wrist
There are these many carpal bones in the human body….
What are 16 carpal bones? (Eight in each hand)

What is the triquetrum bone.
Is carpal bone in the proximal row, is the most medial bone and is similar to a pea shape
What is a pisiform bone?
This carpal bone in the distal row is considered to have four sided figure with no two sides parallel, and is the most lateral of the distal carpal bones
What is the trapezium a.k.a. the multi angular major?
This four sided figure of carpal bones, has two parallel sides is located in the distal row
What is the multangular minor a.k.a. the trapezoid
This is a head shaped bone located in the distal row of the carpal bones
What is capitate bone

What is the Hamate bone
“Stop letting these people touch the cadavers hands” is a mnemonic for these 8 carpal bones
Scaphoid, Lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, Hamate
The middle region of the hand is made up with these bones.
What is the metacarpal bones a.k.a. the metacarpus?
How many metacarpal bones are in the human body?
They are 10 metacarpal bones in the human body five in each hand
Knuckles on the hand are formed by this when the hand is close
What is formed by the head of the metacarpal bones when the hand is closed into a fist.
The proximal base of These “hand” bones, articulates with the distal row of the carpal bones…
What are metacarpal bones?
The proximal head of the metacarpal bones articulates with these bones
What are the proximal phalanges bones a.k.a. the fingers
These “long” bones make up the distal part of the hand and the digits of each finger
What are the phalanges?
Each of these bones in the fingers have a proximal base, a shaft and a distal head
What are the phalanx aka a single finger bone?
There are two phalanges in the first Digit, a.k.a. thumb, a.k.a. pollex, and the rest of the digits have these amount of bones…
What are three?
The first digit of the phalanges is also known as this?
What is the thumb a.k.a. Pollex
