Bones of the lower extremity U2

Question 1

os coxae

Answer 1

the bones of the pelvis, and they are formed by three separate bones that fuse during development.

• the ilium
• ischium
• pubis.

Question 2

ilium

Answer 2

is the most superior of the bones of the os coxae

Question 3

ischium

Answer 3

the posteroinferior bone of the os coxae

contains the ischial tuberosity

Question 4

ischial tuberosity

Answer 4

We bear weight on our ischial tuberosity every time we sit

Question 5

pubis

Answer 5

the anteroinferior bone of the os coxae

Question 6

femur

Answer 6

the longest bone in our body

• It is located between the hip and the knee
• contains the trochanter

Question 7

femoral head

Answer 7

articulates with the acetabulum of the os coxae to form the hip joint.

Question 8

fovea

Answer 8

the attachment point for the ligament of the head of the femur or the ligamentum teres

Question 9

greater trochanter and lesser trochanter

Answer 9

are large sites of muscle attachment on the proximal aspect of the bone.

Question 10

medial and lateral epicondyles

Answer 10

attachment sites on the lateral side of distal aspect of the femur

Question 11

medial and lateral condyles of the femur

Answer 11

articulate with the tibia to form the knee joint

Question 12

patella

Answer 12

a triangular-shaped sesamoid bone that sits within the tendon of the quadriceps muscle
- only articulates with the femur

Question 13

sesamoid bone

Answer 13

a bone that is located within a tendon

- the patella is an example of this

Question 14

medial and lateral articular facets of the tibia

Answer 14

the posterior surfaces that articulate with the femur

- this is where the femor’s condyles will articulate with the tibia

Question 15

tibia

Answer 15

a bone of the lower leg

• carries most of our weight
• articulates with the talus inferiorly

Question 16

fibula

Answer 16

a bone of the lower leg

• carries at most 12 percent of our weight
• articulates with the talus inferiorly

Question 17

medial and lateral tibial condyles

Answer 17

Superiorly they articulate with the femur

- also known as the tibial plateau

Question 18

lateral malleolus

Answer 18

the lateral protrusion at the ankle of the fibula

Question 19

medial malleolus

Answer 19

the medial protrusion at the ankle of the tibia

Question 20

interosseus membrane

Answer 20

holds together the tibia and fibula

-this is located between the two bones

Question 21

tarsal bones

Answer 21

• these form posterior aspect of the foot

- seven of them

Question 22

Calcaneus

Answer 22

We bear weight on this bone when we stand, as it forms our heel.

Question 23

Talus

Answer 23

This bone articulates with the tibia and fibula to form the ankle joint.

Question 24

Navicular

Answer 24

This is the proximal medial bone of the mid-foot. It sits just posterior to the cuneiforms.

Question 25

Cuneiforms

Answer 25

These three bones sit anterior to the navicular on the medial aspect of the mid-foot.
Medial
Intermediate
Lateral

Question 26

Cuboid

Answer 26

This is the large lateral bone of the midfoot.

Question 27

intertarsal joints

Answer 27

located between the tarsal bones.

Question 28

tarsometatarsal joints

Answer 28

located between the cuneiforms or cuboid and the metatarsals

Question 29

metatarsals

Answer 29

metatarsals are the long bones of the foot. They are numbered I-V based, with I being the great to or “big toe.”

Question 30

metatarsophalangeal joints

Answer 30

located between the metatarsals and the phalanges.

Question 31

hallux

Answer 31

the first toe

- this has a proximal and a distal phalanx

Question 32

phalanges

Answer 32

the most distal bones that form the toes

Question 33

linea aspera

Answer 33

this is a line on the posterior side of the femur that serves as an attachment site for many muscles
- as it moves inferiorly, it divided into two lines (the lateral supracondylar line and the medial supracondylar line

Question 34

patellar surface

Answer 34

this is where the patella would articulate with the femur, it is located in the middle of the distal end

Question 35

intercondylar fossa

Answer 35

this is the space between the femurs two condyles at the distal end
