What does the appendicular skeleton consits of? | - upper limbs
- lower limbs
- pelvic girdle
- pectoral (shoulder) girdle |
What does the pectoral girdle consists of? | consists of the clavicle and scapula |
Name the bone | Clavicle |
Name the bone | Acromio-clavicular joint |
Name the bone | Scapula |
What is occuring here? | The medial portion of the clavicle articulates with the first rib and the manubrium |
What is occurring here? | the lateral ends of the clavicle join the scapulae |
True or False: the scapulae joined each other and the axial skelton | false; the scapulae do not join each other nor the axial skeleton |
What does the pectoral girdle provide? | The pectoral girdle provides attachment for many muscles that move the upper limb |
What articulates with the axial skelton? | one the clavicle articulates with the axial skeleton |
True or false: the axial skeleton moves freely | true |
What is the glenoid cavity | the glenoid cavity describes the socket of the shoulder joint |
Why does the glenoid cavity have to be shallow | - the structure being shallow is good for flexibility but bad for stability |
What are the functions of the Clavicles? | the clavicles provide attachment for muscles
the clavicles hold the scapulae and arms laterally
the clavicles transmit compression forces from the upper limbs to the axial skeleton |
Where do the scapule lay in regards to the rib cage? | the scapulae lie on the posterior or dorsal surface of the rib cage
- located between ribs 2-7 |
What are the 3 borders found on the Scapulae? | - superior
- medial (vertebral)
- lateral (axillary) |
What are the 3 angles of the scapulae? | - lateral
- superior
- inferior |

What makes up the forearm? | the forearm is formed from the radius and ulna |
What does the forearm articulate with? | the proximal end of the forearm articulates with the humerus
the distal end of the humerus articulates with the carpals |
How do the radius and ulna articulate with each other? | the radius and ulna articulate with each other via the proximal and distal radioulnar joints |
What membrane is responscible for the interconnection between the radius and ulna? | the interosseous membrane interconnects the radius and ulna |
Standing in an anatomical position, what are the positios of the ulna and radius | radius is lateral
ulna is medial |
What is the main bone responcible for forming the elbow joint with the humerus? | the ulna |
What type of joint allows the forearm to bend on the arm? | hinge joint |
How is the distal end of the ulna seperated from the carpals? | distal end is separated by fibrocartilage |
What role does the ulna play in hand movement? | the ulna plays little to no role in hand movement |
Name the structures | 1. Trochlear notch
2. Radial notch |
Name the structure | proximal radioulnar joint |

Name the structure | Ulnar notch of the radius |
Name the structure | Distal radioulnar joint |
Name the structure | Head of ulna |
Name the structure | Olecranon |

What does the radius articulate with? | the superior surface of the head articulates with the capitulum
medially, the head articulates with the radial notch of the ulna
the distal radius articulates with the carpal bones |
What role does the radius play in hand movement? | the radius contributes heavily to the wrist joint
- when the radius moves, the hand moves with it. |
