1
Q

What are the articulations of the hip joint?

A

head of the femur w/ the acetabulum of the hip bone

2
Q

What connects the head of the femur w/ its shaft?

A

its I-L angled neck

3
Q

What separates the greater and lesser trochanters of the femur?

A

P - intertrochanteric crest

A - intertrochanteric line

4
Q

What are the angles of the shaft?

A

A - slightly bowed

angled M in anatomic position

5
Q

What landmarks arise distally from the linea aspera?

A

M and L supracondylar lines

6
Q

What is the significance of the M and L epicondyles of the femur?

A

they are attachment sites for ligaments of the knee

adductor tubercle - attachment site for muscle

7
Q

What are the distal articulations of the femur?

A

tibia @ the M and L condyles

8
Q

What separates the M and L epicondyles?

A

intercondylar notch

9
Q

What is the distal A articulation of the femur?

A

w/ the patella @ the patellar surface

10
Q

What is the S articulation of the base of the patella?

A

w/ the quadriceps tendon

11
Q

What is the I articulation of the apex of the patella?

A

w/ the patellar liament

12
Q

What are the articulations of the tibia?

A

proximal - w/ the femur @ the tibial plateau
- flat M and L condyles separated by an intercondylar eminence
w/ the fibula proximally at the tibiofibular joint and distally at the tibiofibular syndesmosis

13
Q

What is the tibial tuberosity?

A

located on the A surface below the tibial plateau and is an attachment site for thigh muscles

14
Q

What does the M malleolus form distally?

A

part of the mortise of the ankle joint

15
Q

What connects the shaft of the tibia and fibula?

A

interosseous membrane

16
Q

What are the articulations of the fibula?

A

proximally - head w/ L condyle of tibia @ proximal tibiofibular joint
narrow neck connects head to shaft
distal tibiofibular syndesmosis bonds fibula to distal tibia
distally - L malleolus forms L wall of mortise of ankle joint

17
Q

tarsal bones (7)

A
talus
calcaneus
navicular
cuboid
M cuneiform 
intermediate cuneiform
L cuneiform
18
Q

talus

A

most S tarsal bone
body articulates w/ tibia and fibula @ ankle joint
head articulates w/ navicular bone –> highest part of M arch of foot
I surface articulates w/ calcaneus

19
Q

calcaneus

A

large tarsal bone
articulates S w/ talus and A w/ cuboid
sustentaculum tali - M process that forms part of M arch of foot

20
Q

navicular

A

A to talus

forms part of M arch of foot

21
Q

cuboid

A

A to calcaneus on L side of foot

22
Q

M, intermediate, and L cuneiform bones

A

A to navicular

articulate distally w/ metatarsals

23
Q

5 metatarsals

A

1st (M) –> 5th (L)
bases articulate w/ tarsals proximally
heads articulate w/ proximal phalanges distally
shaft connects head to base
paired sesamoid bones on I surface of head of 1st metatarsal
prominent tuberosity @ base of 5th metatarsal - attachment site for muscles of the leg

24
Q

phalanges

A

2nd-5th have proximal, middle, and distal phalanx

1st: hallux –> only proximal and distal phalanx

25
Q

What forms the L part of the pelvic girdle?

A

hip (coxal) bone
