1

-attached to the axial skeleton via the sacro-iliac joint
-separated from the abdomen, back, and perineum via a continuous line

lower limb

2

what is the lower limb divided into?

-gluteal
-thigh
-leg
-foot

3

posterior region of lower limb

gluteal region

4

extends to the pelvis

anterior thigh

5

important transitions between regions of lower limb

-femoral triangle
-popliteal fossa
-tarsal tunnel

6

contains major blood vessels of the lower limb and one of the major nerves (the femoral)

femoral triangle

7

pass between the thigh and leg through the popliteal fossa

major vessels and nerves

8

pass between the leg and foot through the tarsal tunnel

Most nerves and vessels and flexor tendons

9

major function is support of the body with little energy expenditure

lower limb

10

center of gravity is just anterior to vertebrae SII

standing erect

11

how is energy expenditure reduced while standing?

Hip and particularly knee joints can “lock” while standing

12

second function of the lower limb

locomotion

13

what are the movements at the hips?

-flexion
-extension
-abduction
-adduction
-medial and lateral rotation
-circumduction

14

is primarily a hinge joint that flexes and extends

the knee

15

what are the movements at the ankle?

-dorsiflexion
-plantar flexion

16

what anatomical features work together to maximized efficiency of walking by reducing the amount that the body's center of gravity moves?

-Pelvic rotation minimizes a drop
-Movement of knees to the midline reduces a lateral shift
-Knee flexion minimizes a rise
-Pelvic tilt minimizes a rise

17

how much does the body's center of gravity fluctuate?

only 5 cm in the vertical and lateral planes

18

bones of the gluteal region

-hip
-femur

19

joint between hip and femur

large ball and socket joint

20

-the bone of the thigh, it articulates with the leg at the knee joint
-shares an articular cavity with the patella

femur

21

the principle articulation of the knee

joint between the femur and tibia

22

bones of the leg

-tibia
-fibula

23

large and weight bearing

tibia

24

lateral and does not take part in the knee joint nor bear any weight

fibula

25

formed by a recess formed between the tibia and fibula and part of the talus (tarsal bone)

ankle joint

26

bone of the foot

-tarsals
-metatarsals
-phalanges

27

occurs at joints between the tarsal bones

inversion and eversion of the foot

28

how many tarsal bones are there?

7 tarsal bones

29

what are the 5 metatarsals limited in their movement by?

deep transverse ligaments

30

how many phalanges in digits II-V?
