Where is the Biceps Brachii?
Located at the coracoid process and just above the glenoid fossa
Where is the brachioradialis?
Runs btwn lateral epicondyle of humerus and lateral styloid process, forming the lateral border of the cubital fossa.
Where is the pronator teres?
Located on the medial border of the cubital fossa, runs btwn medial epicondyle of humerus and proximal shaft of radius.
Where is the Triceps Brachii
3 sections:
Long head attaches on the scapula below the glenoid fossa
Lateral & medial heads attach on posterior humerus.
They all gather to attach to the olecranon process of the ulna.
Where is the Anconeus?
Runs btwn lateral epicondyle of humerus and olecranon process of ulna (golfer's muscle)
Which elbow muscles Flex the elbow?
Biceps Brachii (long & short)
Pronator Teres
Which elbow muscles extend the elbow?
Triceps Brachii
Which superficial muscle of the elbow permits supination??
Which superficial muscle of the elbow pronates?
Pronator Quadratus
What articulates with the head of the radius?
Head of radius articulates w/the capitulum of the humerus.
Where is the Medial and lateral epicondyle of the Humerus?
They are the flared portion of the humerus just proximal to the trochlea and capitulum.
Describe the elbow.
A hinged joint formed by the humerus, ulna, and radius. Works w/proximal and distal radioulnar joints.
What is the trochlea articulation of the humerus?
Forms a deep articulation with the trochlear notch of the ulna
Where is the Olecranon Process
Just inferior to the epicondyles. The proximal end of the ulna (is the "lump" we call the elbow.
What is supination of the radioulnar joint?
Outward rotation of the forearm. Palm up
Where is the Radial head?
It is the structure that articulates w/the capitulum of the humerus.
Where is the Medial and Lateral Styloid process?
They are the two lumps at the ends of the radius and the ulna. (just above the wrist)
Where is the elbow joint?
It's formed by the articulations between the trochlea and capitulum of the humerus w/the trochlear notch of the ulna and the radial head.
What is the annular ligament?
Circles the head of the radius. Maintains the proximal radioulnar joint.
Where are the Proximal and Distal Radioulnar joints?
The proximal radioulnar joint is the articulation btwn head of the radius and radial notch of the ulna.

Distal is formed by the articulation btwn head of ulna and ulnar notch of the radius.
What is pronation?
Refers to inward rotation of the forearm. Palm down
What is the Interosseous Membrane
Tough sheet of connective tissue. Runs diagonally btwn radius & ulna. Separates, distributes force and controls slipping.
What superficial muscles act on the elbow?
Biceps Brachii L&S (supinators)
Pronator Teres ABOVE ALL FLEX
Pronator Quadratus
