Answer
  • True
  • False

Question 10

Question
Which of the following is true in respect to the ciliary ganglion?
Answer
  • Sympathetic fibers synapse in the ciliary ganglion.
  • Afferent fibers from the iris and cornea pass through the ganglion
  • The ganglion is located between the optic nerve and medial rectus
  • Parasympathetic fibers in the ganglion are derived from CN VII
  • Parasympathetic fibers in the ganglion are distributed to the retina and lens

Question 11

Question
Which of the nerves below provides parasympathetic supply of glandula parotidea:
Answer
  • n. petrosus profundus
  • n. glossopharyngeus
  • n. trigeminus
  • n. facialis
  • n. vagus

Question 12

Question
The sacral outflow of the parasympathetic (craniosacral) system enters the pelvic Plexus via:
Answer
  • hypogastric nerves
  • pelvic splanchnic nerves
  • pudendal nerves
  • sacral splanchnic nerves

Question 13

Question
Preganglionic parasympathetic nerve fibers within the pelvic (inferior hypogastric) plexus arise from S2, 3, 4 and enter the plexus via:
Answer
  • gray rami communicantes
  • hypogastric nerves
  • pelvic splanchnic nerves
  • sacral splanchnic nerves
  • white rami conummunicantes

Question 14

Question
Choose the statement that does not accurately reflect the differences between the somatic and autonomic motor systems.
Answer
  • Somatic nerve fibers are fast-conducting; autonomic fibers are slow-conducting.
  • Somatic leads to heart muscle; autonomic leads to skeletal muscle.
  • Somatic impulses are excitatory only; autonomic impulses are excitatory or inhibitory.
  • Somatic receptors have a specialized motor end plate; autonomic receptors do not.

Question 15

Question
Which is the true statement regarding the sympathetic nervous system?
Answer
  • Both preganglionic and postganglionic fibers are myelinated.
  • Preganglionic neurons exit the spinal cord in the cervical and sacral regions.
  • Adrenal medulla cells are derived from modified postganglionic sympathetic neurons.
  • The sympathetic nervous system is rarely activated as a unit.

Question 16

Question
Regarding the parasympathetic division of the autonomic nervous system:
Answer
  • parasympathetic preganglionic fibers are found in all cranial nerves
  • parasympathetic vasoconstrictor fibers are present in the salivary glands
  • paraympathetic postganglionic neurons are found in spinal ganglia from T1 to L2
  • parasympathetic postganglionic fibers secrete acetylcholine onto their target organs

Question 17

Question
Regarding the role of the autonomic innervation:
Answer
  • Stimulation of the the sympathetic nerves to the eyes causes pupillary constriction
  • Activation of the sympathetic system causes vasodilatation in the skin
  • Activation of the sympathetic system causes vasoconstriction in the viscera and vasodilatation in the skeletal muscle
  • Stimulation of the vagus nerves speed up the heart

Question 18

Question
The rami communicantes are designated white or gray depending on whether they are
Answer
  • from the sympathetic or parasympathetic system
  • in the thoracic or lumbar region
  • myelinated or not
  • from the white or gray matter of the central nervous system

Question 19

Question
Parasympathetic nerves in the thorax
Answer
  • cause contraction of the muscle in the lung
  • supply sensory fibres to the lung
  • are secretormotor to the oesophagus.
  • cause the longitudinal muscle of the oesophagus to relax.
  • supply sensory fibres to the pericardium.

Question 20

Question
Which of the cranial nerve nuclei listed below are visceromotor (parasympathetic)?
Answer
  • nucleus dorsalis nervi vagi
  • n.salivatorius caudaiis
  • n.ambiguus
  • n.nervi facialis
  • n.solitarius

Question 21

Question
Postganglionic sympathetic neurons
Answer
  • release neurotransmtter acetylcholine
  • have non-myelinated axons
  • send short fibers to the target organs
  • have slow-conducting fibers
  • supply skeletal muscles

Question 22

Question
Regarding the sympathetic division of the autonomic nervous system
Answer
  • acetylcholine is secreted by some sympathetic postganglionic fibers.
  • most sympathetic preganglionic fibers secrete norepinephrine (noradrenaline).
  • sympathetic postganglionic neurons are found in spinal segments from T1 to L2.
  • the sympathetic chain extends from the thoracic to the sacral regions of the spinal cord.
  • sympathetic preganglionic neurons are found in spinal lateral horns.

Question 23

Question
Regarding the parasympathetic division of the autonomic nervous system
Answer
  • parasympathetic preganglionic fibers are found in all cranial nerves.
  • parasympathetic postganglionic neurons are found in spinal ganglia from T1 to L2.
  • parasympathetic postganglionic fibers secrete acetylcholine onto their target organs.
  • parasympathetic preganglionic neurons are found in sacral segments.
  • parasympathetic ganglia are close to the organs.

Question 24

Question

Answer
  • preganglionic parasympathetics
  • inferior hypogastric
