BIOD 151 Module 5 Practice Test 2026 | Most Tested Questions |
Graded A+
1. Describe the role of the musculocutaneous nerve in muscle function.
The musculocutaneous nerve is responsible for innervating the
diaphragm for respiration.
The musculocutaneous nerve innervates muscles in the anterior
compartment of the arm, facilitating flexion at the elbow.
The musculocutaneous nerve provides sensory innervation to the skin
of the forearm.
The musculocutaneous nerve innervates the muscles of the posterior
arm for extension.
2. Which muscle is primarily responsible for dorsiflexion of the foot?
Gastrocnemius
Quadriceps
Tibialis anterior
Soleus
3. During muscle contraction, "cross-bridges" form between:
thick myofilaments and thin myofilaments
sarcoplasmic reticulum and thin myofilaments
transverse tubules and triads
sarcolemma and transverse tubules
None of these
,4. Describe the role of actin in the process of muscle contraction.
Actin is responsible for the release of neurotransmitters at the
neuromuscular junction.
Actin binds to calcium ions to initiate muscle contraction.
Actin provides structural support to the muscle fibers without
participating in contraction.
Actin serves as the thin filament that is pulled by myosin during
muscle contraction, facilitating the shortening of the muscle.
5. If a person experiences weakness in the iliocostalis muscle group, what
functional activities might be affected?
Knee flexion and extension
Wrist flexion and extension
Shoulder abduction and adduction
Spinal extension and lateral flexion
6. What is the origin of the semispinalis at the capitis region?
TP of C7 and T1-T7 and AP of C4-C6
TP of T6-T10
TP of T1-T6
7. Describe the significance of the cervical plexus in relation to muscle
innervation.
The cervical plexus primarily innervates the thigh muscles, aiding in
leg movement.
The cervical plexus does not play a role in muscle innervation.
, The cervical plexus is crucial for innervating neck muscles and the
diaphragm, which are essential for breathing and head movement.
The cervical plexus is responsible for controlling the heart and lungs.
8. Which muscle is unique in that it is the only one to insert on the navicular
bone?
Extensor hallucis longus
Peroneus Tertius
Gastrocnemius
Tibialis posterior
9. Describe the role of the gluteus maximus in hip movement during
contraction.
The gluteus maximus adducts the thigh.
The gluteus maximus stabilizes the spine.
The gluteus maximus flexes the knee joint.
The gluteus maximus extends and laterally rotates the hip joint,
pulling the femur posteriorly.
10. The posterior extrinsic muscle that inserts primarily at the navicular is called
the:
tibialis posterior
peroneus longus
talonavicular
peroneus brevis
, 11. True of the musculocutaneous nerve:
It has motor and sensory components
it lies between the brachialis and brachioradialis
It pierces the biceps brachii muscles
It innervates the muscles of the anterior arm and the anterolateral
forarm
12. What is the primary action of the superior gemellus muscle at the hip joint?
Flexion
Lateral rotation
Adduction
Abduction
13. If a person is unable to control their heart rate consciously, which type of
muscle tissue is responsible for this function?
Cardiac muscle
All muscle types
Smooth muscle
Skeletal muscle
14. A patient demonstrates an inability to lift the toes off of the ground while
walking. This results in the toes dragging on the ground during the swing
phase of gait. Manual muscle testing is performed to determine the most
likely muscle weakness that is contributing to this impairment. Which muscle
is most likely involved? (1.1)
Flexor Digitorum Longus
