12The sacral outflow of the parasympathetic (craniosacral) system enters the pelvic plexus via:
- Ahypogastric nerves
- Bpelvic splanchnic
- Cpudendal nerves

- Cpelvic splanchnic nerves
- Dsacral splanchnic nerves
- Ewhite rami communicates
14Choose the statement that does not accurately reflect the differences between the somatic and autonomic motor systems
- ASomatic nerve fibers are fast-conducting; autonomic fibers are slow- conducting
- BSomatic leads to heart muscles; autonomic leads to skeletal muscle
- CSomatic impulses are excitatory only; autonomic impulses are excitatory or inhibitory
- DSomatic receptors have a specialised have a specialised motor end plate; autonomic receptors do not
15Which is the true statement regarding the sympathetic nervous system?

16Regarding the parasympathetic division of the autonomic nervous system
- Aparasympathetic preganglionic fibers are found in all cranial nerves
- Bparasympathetic vasoconstrictor fibers are present int he salivary glands
- Cparasympathetic postganglionic neurons are found in spinal ganglia from T1 to L2
- Dparasympathetic postganglionic fibers secrete acetylcholine onto their target organs
17Regarding the role of the sympathetic nerves to the eyes causes pupillary constriction
- Astimulation of the sympathetic nerves to the eyes causes pupillary constriction
- Bactivation of the sympathetic system causes vasodilation in the skin
- Cactivation of the sympathetic system causes vasoconstriction in the viscera and vasodilation in skeletal muscle

- Cn. ambiguous
- Dn. nervi facialis
- En. solitarius
21Postganglionic sympathetic neurons
- Arelease neurotransmitter acetylcholine
- Bhave non-myelinated axons
- Csend short fibers to the target organs
- Dhave slow- conducting fibers
- Esupply skeletal muscles
22Regarding the sympathetic division fo the autonomic nervous system
- Aacetylcholine is secreted by some sympathetic postganglionic fibers
- Bmost sympathetic preganglionic fibers secrete norepinephrine (noradrenaline)
- Csympathetic postganglionic neurons are found in spinal segments from T1 to L2
- Dthe sympathetic chain extends from the thoracic to the sacral regions of the spinal cord
- Esympathetic preganglionic neurons are foound in spinal lateral horns
23Regrading the parasympathetic division of the autonomic nervous system
- Aparasympathetic preganglionic fibers are found in all cranial nerves
- Bparasympathetic postganglionic neurons are found in spinal ganglia from T1 to L2
- Cparasympathetic postganglionic fibers secrete acetylcholine onto their target organs
- Dparasympathetic preganglionic neurons are found in sacral segments

24The pelvis splanchnic nerves primarily carry [blank_start]Preganglionic parasympathetics[blank_end] to the [blank_start]inferior hypogastric[blank_end] plexuses
- APreganglionic parasympathetics
- Binferior hypogastric
25The 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
