Appendicular Skeleton

Question 1

2 bones of pectoral girdle

Answer 1

scapula
clavicle

Question 2

how does pectoral girdle connect to axial skeleton

Answer 2

sternoclavicular joint
(between sternum and clavicle)

Question 3

what gives upper limb so much range of motion?

Answer 3

only one joint (sternoclavicular) connecting to axial skeleton. the rest is held in place by ligaments

Question 4

joint between clavicle and scapula

Answer 4

acromioclavicular joint

Question 5

joint that attaches upper limb to pectoral girdle

Answer 5

glenohumeral joint
(humerus + scapula)

Question 6

arm bone

Answer 6

humerus

Question 7

anatomical vs surgical neck of humerus

Answer 7

anatomical closer to glenohumeral joint
surgical below head, where surgeries are done to replace joint

Question 8

bony features at end of humerus

Answer 8

GREATER TUBERCLE (lateral)
LESSER TUBERCLE (anterior)

inbetween them: INTERTUBERCUAR SULCUS
- space for biceps tendon

Question 9

bony features of distal humerus

Answer 9

• LATERAL + MEDIAL EPICONDYLE
• CAPITULUM (lateral) makes joint with RADIUS
• TROCHLEA (medial) makes joint with ulna
• CORONOID PROCESS (anterior) on ulna fits into CORONOID FOSSA when arm flexed
• OLECRANON FOSSA (posterior) fits olecranon on ulna

Question 10

locations of head of radius vs ulna

Answer 10

head of ulna distal
head of radius proximal

Question 11

wrist bones

Answer 11

8 carpals
2 rows, 4 bones each
- schapoid
- lunate
- triquetrum
- pisiform
- trapezium
- trapezoid
- capitate
- hamate

Question 12

names of bone shafts in fingres

Answer 12

phalanx

Question 13

mnemonic to remember carpals (lateral to medial)

Answer 13

stop letting those people touch the cadaver’s hand

Question 14

acetabulum

Answer 14

where ilium, ischium and pubis meet to form a fossa
where lower limb articulates with pelvic gurdle

Question 15

obturator foramen

Answer 15

hole in ischium for obturator nerve

Question 16

bony features of head of femur

Answer 16

GREATER TROCHANTER
LESSER TROCHANTER

Question 17

bony features of distal femur

Answer 17

MEDIAL AND LATERAL
CONDYLES (articular surfaces) + EPICONDYLES (knee ligament attachment points)

Question 18

triangular sesmoid bone

Answer 18

embedded in a tendon
e.g. patella

Question 19

features of tibia and fibula

Answer 19

tibia proximal
- MEDIAL AND LATERAL CONDYLES
- TIBIAL TUBEROSITY
distal
- MEDIAL MALLEOLUS (tibia)
- LATERAL MALLEOLUS (fibula)

Question 20

metacarpals numbered vs metatarsals numbered

Answer 20

carpals: laterally to medially
tarsals: medially to laterally

Question 20

tarsals

Answer 20

7

Question 21

name tarsals

Answer 21

calcaneus
navicular
third (lateral) cuneiform
second (intermediate) cuneiform
first (medial) cuneiform

Question 22

hallux

Answer 22

big toe!

Question 23

fibula structure that forms what we commonly call the “ankle bone”

Answer 23

lateral malleolus

Question 24

capitulum articulates with

Answer 24

head of radius
