  • 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
  • pudendal nerves
  • sacral splanchnic nerves

Question 13

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

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 muscles; autonomic leads to skeletal muscle
  • Somatic impulses are excitatory only; autonomic impulses are excitatory or inhibitory
  • Somatic receptors have a specialised have a specialised 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 myelinted
  • Preganglionic neurons exit the spinal cord in the cervical and sacral regions
  • Adrenal medulla cells are derived from modifies 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 int he salivary glands
  • parasympathetic 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 sympathetic nerves to the eyes causes pupillary constriction
Answer
  • stimulation of the sympathetic nerves to the eyes causes pupillary constriction
  • activation of the sympathetic system causes vasodilation in the skin
  • activation of the sympathetic system causes vasoconstriction in the viscera and vasodilation in skeletal muscle
  • stimulation of the vagus nerves speed up the heart

Question 18

Question
The rami communications 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/ 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 fibers to the lung
  • are secremotor to the oesophagus
  • cause the longitudinal muscle of the oesophagus to relax
  • supply sensory fibers to the pericardium

Question 20

Question

Answer
  • nucelus dorsalis nervi vagus
  • n. salivatorius caudalis
  • n. ambiguous
  • n. nervi facialis
  • n. solitarius

Question 21

Question
Postganglionic sympathetic neurons
Answer
  • release neurotransmitter 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 fo 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 foound in spinal lateral horns

Question 23

Question
Regrading 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 organ

Question 24

Question
The pelvis splanchnic nerves primarily carry [blank_start]Preganglionic parasympathetics[blank_end] to the [blank_start]inferior hypogastric[blank_end] plexuses
Answer
  • Preganglionic parasympathetics
  • inferior hypogastric

Question 25

Question
The pathway of parasympathetic fibers to the lacrimal gland is as follows: CN VII- A [blank_start]greater petrosal nerve[blank_end] : nerve of the pterygoid canal B- [blank_start]pterygopalatine ganglion[blank_end] : zygomatic branch of V2 - C- [blank_start]lacrimal branch of V1[blank_end]
