Lesson 5 - Appendicular Skeleton II

Question 1

Three main joints of lower limbs

Answer 1

Hip, Knee and Ankle

Question 2

Hip bone x2

Answer 2

Hip bone articulates with the sacrum of the axial skeleton

Separated into three bones

Ilium, ischium and Pubis

Obturator foramen is also part of the Hip Bone and is the hole.

Acetabulum is the depression formed in the hip joint at the age of 23

Question 3

Pubic Symphysis Joint

Answer 3

The moveable joint connecting the two hip bones on the inferior end

Question 4

Ilium

Answer 4

Iliac crest (both)

Iliac fossa (ant)

Gluteal surface with lines (post)

posterior superior iliac spine (PSIS)
Anterior superior iliac spine (ASIS)
Anterior Inferior iliac spine (AIIS)
posterior Inferior iliac spine (PIIS)

Greater and lesser sciatic notch (both)

Arcuate line (both)

Question 5

Ischium

Answer 5

Ischial Spine (both)
Ischial tuberosity (post)
Ramus of ischium (ant)

Greater and lesser sciatic notch (both)

Question 6

Ischium to Sacrum

Answer 6

When spine is involved it creates the greater and lesser sciatic foramen. With the help of the sacrospinous and sacrotuberous ligament

Question 7

Pubis

Answer 7

Superior and Inferior pubic ramus

Body of pubis

Pubic ramus

Arcuate and Pectineal line

Question 8

What makes up the Pelvic inlet?

S.A.P.P.P

Answer 8

Sacrum
Arcuate line x2
Pectineal line x2
Pubic crest x2
Pubic symphysis

Question 9

Sex different in Pelvis
Inlet, Greater and Angle

Answer 9

Inlet
Male: narrow and heart shaped
Female: wide and oval

Great:
Male: deep and narrow <90
Female: wide and shallow >90

Question 10

Femur Head

Answer 10

Head of Femur
Greater trochanter (opposite to head)
Trochanteric fossa (post)
Neck of femur
Lesser trochanter (same side as head)
Intertrochanteric line (ant)
Intertrochanteric crest (post)

Femur head articulates with acetabulum of hip to form hip joint

Question 11

Femur Shaft

Answer 11

Anterior =smooth
Posterior = rough for muscle attachment

Pectineal line
Gluteal tuberosity
Medial and later lip of linea aspera

(all post)

Question 12

Distal femur

Answer 12

Epi=above

Highest to lowest

Adductor tubercle
Medial and Lateral Epicondyle
Medial and Lateral Condyle
Patellar surface

Question 13

Fibula

Answer 13

Head and Neck of Fibula

Lateral and Medial surface
Posterier Surface

Lateral Malleolus (both)

Interosseus Membrane, slight moveable joint, holding tib and fib together

Question 14

Tibia

Answer 14

Tibial plateau (post and sup)
Tibial Tuberosity (ant)
Soleal line (post)

Lateral and Medial surface
Posterier Surface

Malleolar groove (post)
Medial Malleolus (both)

Question 15

Knee joint

Answer 15

Knee joint articulates between the medial and lateral condyles of the femur with the plateau of the tibia

Question 16

Knee joint ligaments

Answer 16

LCL: Lateral collateral ligament
MCL: Medial collateral ligament
ACL: Anterior collateral ligament
PCL: Posterier collateral ligament

Question 17

Phalanges (feet)

Answer 17

Distal, middle and proximal phalanges (only distal and proximal for big toe)

Question 18

Metatarsal

Answer 18

1-5, medial to lateral. Inferior metatarsal one has a sesamoid bone

Question 19

Tarsals (7)

Answer 19

Base of foot, 7 bones. Cuneiform (3) lateral, intermediate and medial. Navicular, Cuboid, Talus or Calcaneus

Question 20

Ankle joint

Answer 20

Ankle joint articulates between the tibia, fibula and the Talus of the foot

Question 21

Arches of the foot

Answer 21

Transverse arch- over top, running across the foot horizontally

Longitudinal arch is from back of foot to front

Question 22

Plantar fascia

Answer 22

runs at bottom of foot and stabilizes the arches
