We call it GH joint for short
Glenohumeral joint
It is at the opposite end of the ulna from the ulnar head
Where is the olecranon process?
Originates on distal 1/4 of ulna and inserts on distal 1/4 of radius
Where is the pronator quadratus?
It articulates with the radius
where is the scaphoid bone?
Scapular retraction, elevation and downward rotation
What movements does Rhomboid do?
Inserts onto the deltoid tuberosity.
Where do the deltoids insert?
The beer drinking muscle
What is brachioradialis also known as?
It's innervated by the median nerve
What is pronator teres, pronator quadratus
It flexes the wrist and does ulnar deviation
Flexor carpi ulnaris
What movements does the serratus anterior do?
Subscapularis inserts here
What is the lesser tubercle?
They are both innervated by the radial nerve
What is the triceps and brachioradialis
It helps biceps brachii with supination
Supinator
Is often used to replace damaged tendons when present
It assists with shoulder flexion and is a stabilizer.
What does the coracobrachialis do?
It's not a prime mover of any joint action, assists with elbow extension
What does the anconeous do
Is also know as golfer's elbow

What is the radial nerve
The serratus anterior plus the upper and lower trapezius muscles
What muscles complete upward rotation
These muscles make up the rotator cuff.
Supraspinatus, infraspinatus, teres minor and subscapularis
Has a hard end feel
Elbow extension
It compressed the median nerve
Is considered the mid point of the carpals
