What is UVWXYZ?
The anatomic neck
Give two muscles which attach to the humerus
Bicep brachii and pectoralis major
What does humerus serve as?
Leaver for arm
Where does the humerus articulate with the scapula? Where does the humerus articulate with the radius and ulna?
At the glenohumeral joint for scapula At the elbow joint for the radius and ulna
Where is a common fracture on the humerus?
On the surgical neck
What nerve is found around surgical neck of humerus, and what could a fracture result in?
Axillary nerve A fall on surgical neck could compress or damage axillary nerve causing parasthesia (pins and needles) and a loss of motor function
