QUESTIONS AND CORRECT VERIFIED ANSWERS/
ALREADY GRADED A+ (MOST RECENT!!)
1. Where are the larger groups of lymph nodes and lymphatic
vessels typically found in the body?
A) Near the brain and spinal cord
B) Near the mammary glands, axilla, and groin
C) Near the heart and lungs
D) Near the kidneys and liver
Correct Answer: B
Rationale: Large clusters of lymph nodes are strategically
located in areas where infection or malignancy commonly
spreads, including the axilla (armpit), groin (inguinal region), and
mammary glands (breast), as well as the neck and abdomen.
2. What structures do somatic plexuses form from?
A) Dorsal rami of spinal nerves
B) Ventral rami of spinal nerves
C) Dorsal root ganglia
D) Sympathetic chain ganglia
Correct Answer: B
1
,Rationale: Somatic plexuses (cervical, brachial, lumbar, sacral)
are formed by the ventral rami (anterior divisions) of spinal
nerves, which carry motor and sensory fibers to the limbs and
trunk.
3. Which somatic plexus originates from spinal nerves C5-T1?
A) Cervical plexus
B) Brachial plexus
C) Lumbar plexus
D) Sacral plexus
Correct Answer: B
Rationale: The brachial plexus is formed by the ventral rami of
C5 through T1 and innervates the upper limb, shoulder, and some
neck muscles.
4. Which somatic plexus originates from spinal nerves L1-L4?
A) Cervical plexus
B) Brachial plexus
C) Lumbar plexus
D) Sacral plexus
Correct Answer: C
Rationale: The lumbar plexus is formed by the ventral rami of
2
,L1-L4 and gives rise to nerves such as the femoral and obturator
nerves, innervating the anterior and medial thigh.
5. Which somatic plexus originates from spinal nerves L5-S4?
A) Cervical plexus
B) Brachial plexus
C) Lumbar plexus
D) Sacral plexus
Correct Answer: D
Rationale: The sacral plexus is formed by the ventral rami of L4-
S4 (with L5 contributing significantly) and gives rise to the sciatic
nerve and others innervating the posterior thigh, leg, and foot.
6. Which somatic plexus originates from spinal nerves C1-C5?
A) Cervical plexus
B) Brachial plexus
C) Lumbar plexus
D) Sacral plexus
Correct Answer: A
Rationale: The cervical plexus is formed by the ventral rami of
C1-C4 (and sometimes C5), supplying the neck, diaphragm
(phrenic nerve), and some shoulder muscles.
3
, 7. What is a visceral plexus?
A) A network of somatic motor nerves
B) A combination of sympathetic, parasympathetic, and visceral
afferent fibers
C) A collection of lymph nodes
D) A network of blood vessels
Correct Answer: B
Rationale: Visceral plexuses (e.g., celiac, hypogastric) are
autonomic nerve networks that contain sympathetic,
parasympathetic, and visceral afferent (sensory) fibers,
surrounding abdominal and pelvic organs.
8. Which of the following is an example of a visceral plexus?
A) Brachial plexus
B) Celiac plexus
C) Lumbosacral plexus
D) Cervical plexus
Correct Answer: B
Rationale: The celiac (solar) plexus is the largest autonomic
plexus, located in the upper abdomen and innervating the
stomach, liver, pancreas, and other digestive organs.
