Musculoskeletal anatomy - Part 1

Congratulations - you have completed Musculoskeletal anatomy - Part 1. You scored %%SCORE%% out of %%TOTAL%%. Your performance has been rated as %%RATING%%
Your answers are highlighted below.
Question 1
Which of the following is not a boundary of the pelvic outlet?
A
Coccyx
B
Ischial tuberosity
C
Pubic symphysis
D
Sacrospinous ligament
E
Sacrotuberous ligament
Question 1 Explanation: 
the sacrospinous ligament attaches to the ischial spine which is not a bony landmark of the pelvic outlet
Question 2
In the anatomical position, the anterior superior iliac spine lies in the same vertical plane with
A
Anterior inferior iliac spine
B
Iliopubic eminence
C
Ischial spine
D
Ischial tuberosity
E
Pubic symphysis
Question 2 Explanation: 
The pelvis is tilted anteriorly in the anatomical position and the ASIS and pubic symphysis are the two most anterior points.
Question 3
The linea aspera is a bony feature of which bone?
A
Calcaneus
B
Femur
C
Fibula
D
Talus
E
Tibia
Question 3 Explanation: 
Linea aspera is found on the posterior surface of the femur
Question 4
Which muscle attaches to the lesser trochanter of the femur bone?
A
Gluteus medius
B
Gluteus minimus
C
Obturator internus
D
Piriformis
E
Psoas major
Question 4 Explanation: 
The other muscles all attach to certain points of the greater trochanter
Question 5
What is the major function of the iliacus muscle on the hip joint?
A
Abduction
B
Extension
C
External rotation
D
Flexion
E
Internal rotation
Question 5 Explanation: 
Iliacus and psoas major are two strong flexors of the hip joint. They combine to form the iliopsoas.
Question 6
Which muscle has the same nervous supply as the obturator internus?
A
Inferior gemllus
B
Obturator externus
C
Piriformis
D
Quadratus femoris
E
Superior gemellus
Question 6 Explanation: 
They are both supplied by the nerve to obturator internus
Question 7
Which of the following is not a clinical manifestation of a femoral nerve injury?
A
Loss of hip flexion
B
Loss of knee extension
C
Loss of sensation over anteromedial aspect of thigh
D
Wasting of quadriceps femoris muscle
E
Weakened hip flexion
Question 7 Explanation: 
Femoral injury will only cause impaired hip flexion instead of complete loss of the function because the iliopsoas muscle is still functioning.
Question 8
Which muscle is not supplied by the obturator nerve?
A
Adductor brevis
B
Adductor longus
C
Adductor magnus
D
Gracilis
E
Obturator internus
Question 8 Explanation: 
Obturator nerve innervates muscles of the medial (adductor) compartment of the thigh. Don't be trick into thinking the obturator internus is supplied by it because they are similarly named.
Question 9
What is the spinal nerve root value of the iliohypogastric nerve?
A
T12
B
L1
C
L2
D
L3
E
L4
Question 9 Explanation: 
Arising from the lumbar plexus, the iliohypogastric nerve and ilioinguinal nerve both originate from the anterior ramus of L1 spinal nerve.
Question 10
Which nerve is at emergent risk with a posterior hip joint dislocation?
A
Femoral nerve
B
Genitofemoral nerve
C
Lateral cutaneous nerve of thigh
D
Posterior cutaneous nerve of thigh
E
Sciatic nerve
Question 10 Explanation: 
Up to 20% of posterior hip dislocation will lead to sciatic nerve injury
Question 11
Muscles in the floor of the femoral triangle include all except
A
Adductor longus
B
Adductor magnus
C
Iliacus
D
Pectineus
E
Psoas major
Question 12
Dermatomes of lower limb:
A
S1 supplies the great toe
B
L2 supplies anterior upper thigh
C
L3 supplies lateral calf
D
L4 supplies medial thigh
E
L5 supplies medial calf
Question 12 Explanation: 
S1 supplies the posterior thigh and the little toe. L3 supplies anterior middle part of thigh. L4 supplies anterior lower thigh and medial calf. L5 supplies lateral calf.
