44
Q

What are the posterior muscles of the elbow?

A
  • Triceps brachii
    • Attaches to olecranon process of the ulna bone
    • 3 heads (hence triceps)
      • Lateral head
      • Long head
      • Medial head
    • Extends arm at glenohumeral joint (shoulder) and extends arm at elbow joint
45
Q

Where does the tricep brachii attach to?

A
  • Attaches to olecranon process of the ulna bone
46

A
  • Extends arm at glenohumeral joint (shoulder) and extends arm at elbow joint
48
Q

What nerve supplies the tricep brachii?

A

Radial nerve travels on surface of posterior humerus deep to muscle, supplying tricep

49
Q

What often damages the radial nerve?

A

Humeral fracture

50
Q
