BIO 142: CHAPTER 15: AUTONOMIC NERVOUS SYSTEM:
TEST QUESTIONS WITH COMPLETE SOLUTIONS
Where are the ganglia located in the parasympathetic versus sympathetic division
respectively? -- Answer ✔✔ Parasympathetic: close to or within effector
Sympathetic: close to spinal cord
Fill the following for the sympathetic division
1. Origin of Fibers
2. Length of Fibers
3. Location of Ganglia -- Answer ✔✔ 1. lateral horns of T1 - L2 segments of spinal cord
(thoracolumbar)
2. Short preganglionic axons versus long postganglionic axons
3. Ganglia is close to the vertebral column
Fill in the following for the parasympathetic division
1. Origin of Fibers
2. Length of Fibers
3. Location of Ganglia -- Answer ✔✔ 1. Brainstem nuclei and S2-S4 segments of spinal
cord (craniosacral)
2. long preganglionic axon versus short postganglionic axons
3. Ganglia close to or within effector
,Why is the parasympathetic a local response? -- Answer ✔✔ due to long preganglionic
neurons with limited branches, only effect one or a few effectors at one time
Why does the sympathetic activation have mass activation? -- Answer ✔✔ due to short
preganglionic axons with many branches, may effect several effectors at one time
CN III -- Answer ✔✔ Oculomotor Nerve
What is the target of the CN III -- Answer ✔✔ eye (focus lens, constrict iris)
CN VII -- Answer ✔✔ Facial Nerve
What is the target of the CN VII -- Answer ✔✔ Lacrimal glands and salivary glands
(increase secretion)
CN IX -- Answer ✔✔ Glossopharyngeal Nerve
What is the target of the CN IX -- Answer ✔✔ Parotid Gland (increase secretion)
CN X -- Answer ✔✔ Vagus Nerve
What is the target of the CN X -- Answer ✔✔ thoracic organs, most abdominal organs,
gonads (increased mucus production and decreased airway diameter, decrease in heart
rate and force, increased smooth muscle motility and secretory activity)
Where do the pelvic splanchnic nerves originate? -- Answer ✔✔ sacral regions of the
spinal cord
, What are the target organs of the sacral components of the parasympathetic
components (and 4 effects) -- Answer ✔✔ Abdominal and pelvic effectors
1. Smooth muscle contraction
2. Secretory activity in digestive tract
3. contraction in bladder wall
4. erection of clitoris and penis
What cranial nerves are associated with the parasympathetic division? -- Answer ✔✔ 1.
Oculomotor Nerve (CN III)
2. Facial Nerve (CN VII)
3. Glossopharnygeal Nerve (CN IX)
4. Vagus Nerve (CN X)
What organs are innervated by the pelvic splanchnic nerves? -- Answer ✔✔ 1.
Descending Colon
2. Rectum
2. Bladder
3. Sexual Organs
Where are the sympathetic "string of pearls" located? -- Answer ✔✔ lateral to the
vertebral column
What are the four types of sympathetic truck ganglia? -- Answer ✔✔ 1. Cervical
2. Thoracic
3. Lumbar
4. Sacral
Horner Syndrome is an injury where? -- Answer ✔✔ 1. Cervical sympathetic trunk
2. T1 Trunk Ganglion
