Anatomy 1

Question 1

Depression on femoral head and associated ligament

Answer 1

fovea

Ligamentum teres

Question 2

Acetabulum parts and associated ligament

Answer 2

acetabular margin –> outside of: acetabular labrum
acetabular notch - transverse acetabular ligament
Acetabular fossa
Glenoid labrum

Question 3

External fibrous layer of hip jt - name and attachment points

Answer 3

Fibrous capsule

• Peripheral to acetabular margin & transverse acetabular ligament
• Distally: femoral neck
• Ant: intertorchanteric line & root of the greater trochanter
• Posterior: intertrochanteric line of femur

Question 4

Internal fibrous layer of hip jt

Answer 4

Synovial membrane

- Covers fibrous capsule, articular cartilage and nonarticular area of the acetabulum

Question 5

Thicking of external fibrous layer of hip jt in some places –> 3 intrinsic lig:

Answer 5

1. Iliofemoral
2. Pubofemoral
3. Ischiofemoral

Question 6

Iliofemoral ligament

Answer 6

AIIS & acetabular rim –> intertrochanteric line

Brings femoral head tightly into the acetabulum when standing upright
Prevents hyperextension

Question 7

Pubofemoral

Answer 7

Obturator crest of pubic bone –> blends with iliofemoral lig

Tightens during extension & abduction
Prevents overabduction

Question 8

Ischofemoral

Answer 8

Acetabular margin –> neck of femur

Limits IR of hip

Question 9

What passes through the longitudinal synovial folds on synovial membrane covering the neck of femur?

Answer 9

Subsynovial retinacular arteries (from medial and lateral circumflex femoral)

Question 10

What artery lies inside of ligamentum teres?

Answer 10

Artery to head of the femur (from obturator artery)

Question 11

Hip flexors

Answer 11

Iliopsoas
Sartorius
Rectus femoris
Pectinus

Question 12

Hip extensors

Answer 12

Gluteus max

Hamstrings

Question 13

Abduction

Answer 13

Gluteus minimus and medius
Tensor fascia lata
Sartorius

Question 14

Adduction

Answer 14

Adductor brevis
Adductor longus
Adductor magnus
Pectineus
Gracilis

Question 15

Medial Rotation

Answer 15

Gluteus minimus and medius

Tensor fascia lata

Question 16

Lateral rotation

Answer 16

Piriformis
Obturator externus
Obturator internus
Gemelli
Quadratus femoris
Gluteus maximus

Question 17

where does Medial circumflex artery come from

Answer 17

Profunda femoris

Question 18

Where does medial circumflex artery pass

Answer 18

posteriorly

Question 19

Branches of medial circumflex artery

Answer 19

Transverse —> cruciate anastamoses (@ level of lesser trochanter)

Ascending —> trochanteric anastamoses (trochanteric fossa)& posterior retinacular branches (head and neck of femur)
