| How many bones are in the appendicular skeleton? | 126 Bones |
| Which bones make up the pectoral girdle? | Clavicles/ Scapulae |
| Where does the pectoral girdle articulate with the axial skeleton? | With the manubrium |
| Which end of the clavicle articulates with the manubrium? Which end articulates with the scapula? | Sternal(medial)/ Acromial(lateral) |
| What are the three sides of the body of the scapulae called? | Superior/Medial/Lateral border |
| Where does the scapula articulate with the clavicle? (process name) | Acromion |
| Where does the scapula articulate with the humerus? (cavity name) | Glenoid cavity |
| Which two bones make up the forearm? | Radius(lateral)/ Ulna(medial) |
| How are the radius and ulna connected along their shafts? | Interosseous membrane |
| What are the four PROXIMAL carpal bones? The four distal? | Scaphoid/Lunate/Triquetrum/Pisiform |
| What are the four proximal carpal bones? The four DISTAL? | Trapezium/Trapezoid/Capitate/Hamate |
| How are the metacarpals numbered? | I-V/ Thumb is I (lateral) |
| Which of the hand digits have two phalanges and which have three? | Pollex(thumb)/ Fingers |
| Which bones fuse to form the hip bones in adulthood? | Ilium/ Ischium/ Pubis |
| What is the acetabulum and why is its structure significant? | Hip socket/ Articulates with head of the femur |
| Where does the hip bone articulate with the femur? | Acetabulum |

| Know the differences between the male and female pelvis. Why do these differences exist? | Female: Smoother and lighter, Less prominent muscle and ligament attch, more borad and shorter, enlarged pelvic outlet/ Child bearing |
| What type of bone is the patella? What is the function of these types of bones? (recall from chapter 6) | Sesamoid bone/ Kneecap |
| Which two bones make up the lower leg? | Tibia & Fibula |

| Which of the foot digits have two phalanges and which have three? | Hallux(big toe)/ Four toes |
| What is sexual dimorphism? | Distinct difference in size or appearance and between the sexual organs. |
| Know the sex differences from slides 71-73. | |
| Why are bone markings generally less prominent in females than males? | Heavier bones and more prominent bone marking suggest more muscle mass |
