Trick question:

The arm has only one bone: the humerus. The radius and ulna form the forearm.
What are the three long bones of the upper extremity?
Humerus

Radius

Ulna
With which bones does the humerus articulate?
Proximally: scapula

Distally: both the radius and the ulna
The rounded portion of the proximal humerus that fits into the glenoid fossa is called the...
Head
What and where is the anatomical neck of the humerus?
Oblique groove just distal to the head but proximal to the greater and lesser tubercles.
The two projections near the proximal end of the humerus are the...
Greater and lesser tubercle
Where is the greater tubercle located and which direction does it project in anatomic position?
Lies just distal to the anatomical neck, projects laterally
Where is the lesser tubercle located and which position does it project in anatomic position?
Lies just distal to the anatomical neck, like the greater tubercle, but projects anteriorly
The groove between the two tubercles is known as the...
Intertubercular sulcus
What and where is the surgical neck of the humerus?
Narrowing of the humerus just distal to the tubercles
Why is the surgical neck of the humerus called the surgical neck?
Fractures often occur here
The roughened, V-shaped area in the middle portion of the humeral shaft is called the...

Which bone is the olecranon part of?
Ulna
Which bone does the ulna articulate with at its proximal end?
Both the humerus and the radius.
With which region of the humerus does the ulna articulate?
Trochlea
With which region of the radius does the proximal ulna articulate?
Head of the radius
The little bump at the distal end of the posterior ulna is called the...
Styloid process of the ulna
What is the longest bone of the forearm?
The ulna
Which end of the radius is known as the head?
Proximal end
With which region of the humerus does the head of the radius articulate?
Capitulum ("head to head")
The bump on the lateral portion of the distal radius is called the...
