Graded A+
1. Your patient is in a seated position with his feet flat on the floor. He is having
difficulty lifting his toes off the floor. What muscle(s) is impaired from
contracting?
A&C
Tibialis anterior
Gastrocnemius (for plantar flexion - lifting heel)
Tibialis posterior
Extensor digitorum longus
B&D
2. What is the primary action of the Zygomaticus Minor muscle?
Depresses the lower lip
Flexes the cheek
Elevates the upper lip
Retracts the corner of the mouth
3. What is one of the primary actions of the Trapezius muscle?
Flexion of the elbow
Extension of the knee
Elevation of the scapula
Abduction of the shoulder
,4. Identify the muscle, origin, and insertion points on the picture below.
E. A and B combined
B. Muscle: Internal abdominal oblique, Origin: Inguinal ligament, Iliac
crest and thoracolumbar fascia, Insertion: Lower three ribs.
C. Muscle: Transversus Abdominis, Origin: Inguinal ligament, Iliac crest,
thoracolumbar fascia, Lower costal cartilages, Insertion: Abdominal
aponeurosis
A. Muscle: External abdominal oblique, Origin: Anterior Iliac crest,
Pubic bone, and abdominal aponeurosis, Insertion: lower eight ribs.
D. None of the above
5. If a patient has damage to the lumbar plexus, which muscle group in the thigh
would likely be affected?
Hamstrings
Gluteals
Adductors
Quadriceps femoris
,6. What is the process called when cross-bridges attach and detach during
muscle contraction?
Actin sliding
Calcium release
Muscle relaxation
Cross-bridge cycling
7. Which protein myofilament is primarily pulled during muscle contraction?
Myosin
Actin
Troponin
Tropomyosin
8. Which bone is primarily affected by the contraction of the gluteus maximus
muscle?
Pelvis
Tibia
Humerus
Femur
9. What is the name of the muscle primarily responsible for standing on your
toes?
Gastrocnemius
Quadriceps
Tibialis anterior
, Soleus
10. Contraction of which of the following muscles results in flexion of the hip
joint?
iliopsoas
rectus femoris
All of the above can flex the hip joint
sartorius
adductor longus
11. A nerve is a cluster of nerve fibers found in the central nervous system.
true
false
12. Describe the composition of the A band in muscle tissue and its significance
in muscle contraction.
The A band is made up of connective tissue and does not play a role
in contraction.
The A band contains only thin filaments and is not involved in muscle
contraction.
The A band contains thick filaments and is important for muscle
contraction as it overlaps with thin filaments.
The A band is where muscle fibers are innervated by motor neurons.
13. What is the insertion point of the biceps brachii muscle?
Coracoid process
Radial tuberosity
