The two parts of this video will cover the following bones:

The shoulder girdle (pectoral girdle) is comprised of the clavicle and scapula.

  Clavicle: collar bone  
acromial end: articulates with acromion process of scapula 
sternal end: articulates with sternum

  Scapula: shoulder blade
   acromion (acromion process): tip of shoulder
   glenoid cavity: articulates with head of humerus
   spine: posterior long projection
   supraspinous fossa: area above the spine
   infraspinous fossa: area below the spine
   subscapular fossa: anterior surface of scapula

Upper extremity
  Humerus
   head; articulates with glenoid cavity of scapula
anatomical neck: border of the head 
surgical neck: area closer to transition to shaft, common fracture site
greater tubercle: muscle attachment site
lesser tubercle: muscle attachment site
deltoid tuberosity: bump where deltoid muscle attaches
   trochlea; articulates with trochlear notch of ulna
   capitulum: articulates with the head of the radius
olecranon fossa: depression on posterior aspect of humerus where olecranon process inserts.
   medial epicondyle: muscle attachment site
lateral epicondyle: muscle attachment site
 
  Radius
   head: articulates with the capitulum of the humerus
neck: between the head and shaft
radial tuberosity: insertion point for biceps brachii muscle
   ulnar notch: articulation site for distal ulna
radial styloid process: forms distal lateral bump of the wrist; site of ligament attachment
 
  Ulna
   olecranon process: proximal ulna, point of elbow
   trochlear notch: articulates with trochlea of humerus 
radial notch: proximal articulation area for head of radius
ulnar styloid process: form the distal medial bump of the wrist; site of ligament attachment
 
  Carpals: 8 wrist bones
 
  Metacarpals: 5 hand bones numbered 1 thru 5, form palm of hand
 
Phalanges: bones of the digits (fingers)
each digit (except the thumb) has three phalanges
proximal phalanx, middle phalanx, and distal phalanx
