2 What bone is this and is it the left or right?
Right scapula
2 Which picture is the anterior and posterior?
Left is anterior, right is posterior
What makes up the shoulder joint?
The glenohumeral joint - the humerus articulates in the glenoid fossa of the scapula
How can you tell if the scapula is the left or right?
The acromion and glenoid fossa always face laterally
What is the largest and longest bone of the upper extremity?
Humerus
What is the location of the ulna in relation to the radius?
The ulna is medial, the radius is lateral
What is the relationship of the olecranon process to the olecranon fossa?
The olecrenon process of the ulna articulates with the fossa of the posterior humerus to create the elbow joint

3 Which picture is the anterior and posterior?
Left is anterior, right is posterior
What landmark of the humerus is located medially? Is it associated more with the anterior or posterior side?
Trochlea, posterior
What landmark of the humerus is located laterally? Is it associated more with the anterior or posterior side?
Capitulum, anterior
What does the trochlea articulate with?
The trochlear notch of the ulna to make the elbow joint
What does the capitulum articulate with?
The head of the radius glides along the capitulum

What articulating surfaces make up the elbow joint?
The trochlea of the humerus articulates with the trochlear notch of the ulna; the olecranon process of the ulna articulates with the olecranon fossa of the humerus
4 What are these bones and are they the right or the left?
On the left picture, the left is the radius and the right is the ulna; this is the right forearm
4 Which picture is the anterior and posterior?
The left is the anterior, the left is the posterior
What two movements does the radioulnar joint make?
Pronation and supination
What is pronation?
Palm down - radius twists over the ulna
What is supination?
Palm up
At what landmark is the radioulnar joint located?
The radial tuberosity
Which forearm bone is major at the elbow joint?
Ulna
Which forearm bone is major at the wrist joint?
Radius
