What is the only bone of the thigh?

Femur

2

What is the heaviest, strongest bone in the body?

Femur

3

The ball-like head of the femur articulates with which bone via which of its feature?

Articulates with the hip bone via the acetabulum.

4

How are the knees brought in line with the body's center of gravity (Hint: femur plays a role)?

The femur angles medially as it runs down the leg bones.

5

The patella is which type of bone?

Short bone, specifically a sesamoid bone.

6

The patella is enclosed in which tendon?

Quadriceps tendon

7

The quadriceps tendon secures which thigh muscles to what bone?

Secures the anterior thigh muscles to the tibia.

8

The greater trochanter is a marking of which bone in the lower appendicular skeleton?

Femur

9

What type of projection is the greater trochanter?

Large lateral projection

10

The greater trochanter serves as a site for what type of attachment and where specifically?

Serves as a site for muscle attachment on the proximal femur

11

The lesser trochanter is a marking of which bone in the lower appendicular skeleton?

Femur

12

The lesser trochanter has what type of projection?

Large posteromedial projection

13

The lesser trochanter serves as a site for what type of attachment and where specifically?

Serves as a site for muscle attachment on the proximal femur

14

The patellar surface is a marking of which bone in the lower appendicular skeleton?

Femur

15

Describe the type of surface of the patellar surface and where does it lie between?

Smooth distal anterior surface between the condyles.

16

The patellar surface articulates with what specific sesamoid bone?

Patella.

17

Which 2 bones form the skeleton of the leg?

1. Tibia

2. Fibula

18

Which of the 2 bones forming the skeleton of the leg bears the weight of the bone of the leg?

Tibia

19

Which of the 2 bones forming the skeleton of the leg is larger and medial in standard anatomical position?

Tibia

20

Does the fibula take any part in forming the knee joint?

No.

21

The proximal head of the fibula articulates with what bone marking of the tibia?

Lateral condyle of the tibia.

22

The lateral condyle is a marking of what bone in the lower appendicular skeleton?

Tibia

23

What type of surface is the lateral condyle of the tibia?

Concave surface

24

The lateral condyle of the tibia articulates with what marking of the femur?

With the lateral condyle of the femur

25

The inferior region of the lateral condyle of the tibia articulates with what bone?

Fibula

26

When the inferior region of the lateral condyle of the tibia articulates with the fibula, what joint is formed?

superior tibiofibular joint

27

The medial condyle is a marking of what bone in the lower appendicular skeleton?

Tibia

28

What type of surface is the medial condyle of the tibia?

Concave surface

29

The medial condyle of the tibia articulates with what bone marking of the femur?

Medial condyle of the femur

30

The tibial tuberosity is a marking of what bone in the lower appendicular skeleton?

Tibia

31

What type of surface is the tibial tuberosity?

Roughened anterior surface

32

The tibial tuberosity is the site of what type of attachment?

Patellar ligament attachment

33

The anterior border or anterior crest is a marking of what bone in the lower appendicular skeleton?

Tibia

34

Morphologically describe the bone that forms the anterior border or crest.

Sharp ridge of bone

35

The medial malleolus is a marking of what bone in the lower appendicular skeleton?

Tibia

36

The medial malleolus forms what feature of the ankle?

Forms the medial bulge of the ankle

37

The lateral mallelolus is a bone marking of which bone in the lower appendicular skeleton?

Fibula

38

The lateral malleolus forms what feature of the ankle?
