10Which of the following is true in respect to the ciliary ganglion?
- ASympathetic fibers synapse in the ciliary ganglion.
- BAfferent fibers from the iris and cornea pass through the ganglion
- CThe ganglion is located between the optic nerve and medial rectus
- DParasympathetic fibers in the ganglion are derived from CN VII
- EParasympathetic fibers in the ganglion are distributed to the retina and lens
11Which of the nerves below provides parasympathetic supply of glandula parotidea:
- An. petrosus profundus
- Bn. glossopharyngeus
- Cn. trigeminus
- Dn. facialis
- En. vagus
12The sacral outflow of the parasympathetic (craniosacral) system enters the pelvic Plexus via:
- Ahypogastric nerves
- Bpelvic splanchnic nerves
- Cpudendal nerves
- Dsacral splanchnic nerves
13Preganglionic parasympathetic nerve fibers within the pelvic (inferior hypogastric) plexus arise from S2, 3, 4 and enter the plexus via:
- Agray rami communicantes
- Bhypogastric nerves
- Cpelvic splanchnic nerves
- Dsacral splanchnic nerves
- Ewhite rami conummunicantes
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 muscle; autonomic leads to skeletal muscle.
- CSomatic impulses are excitatory only; autonomic impulses are excitatory or inhibitory.
- DSomatic receptors have a specialized motor end plate; autonomic receptors do not.
15Which is the true statement regarding the sympathetic nervous system?
- ABoth preganglionic and postganglionic fibers are myelinated.
- BPreganglionic neurons exit the spinal cord in the cervical and sacral regions.
- CAdrenal medulla cells are derived from modified postganglionic sympathetic neurons.
- DThe sympathetic nervous system is rarely activated as a unit.
16Regarding the parasympathetic division of the autonomic nervous system:
- Aparasympathetic preganglionic fibers are found in all cranial nerves
- Bparasympathetic vasoconstrictor fibers are present in the salivary glands
- Cparaympathetic 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 autonomic innervation:
- AStimulation of the the sympathetic nerves to the eyes causes pupillary constriction
- BActivation of the sympathetic system causes vasodilatation in the skin
- CActivation of the sympathetic system causes vasoconstriction in the viscera and vasodilatation in the skeletal muscle
- DStimulation of the vagus nerves speed up the heart
18The rami communicantes are designated white or gray depending on whether they are
- Afrom the sympathetic or parasympathetic system
- Bin the thoracic or lumbar region
- Cmyelinated or not
- Dfrom the white or gray matter of the central nervous system
19Parasympathetic nerves in the thorax
- Acause contraction of the muscle in the lung
- Bsupply sensory fibres to the lung
- Care secretormotor to the oesophagus.
- Dcause the longitudinal muscle of the oesophagus to relax.
- Esupply sensory fibres to the pericardium.
20Which of the cranial nerve nuclei listed below are visceromotor (parasympathetic)?
- Anucleus dorsalis nervi vagi
- Bn.salivatorius caudaiis
- Cn.ambiguus
- Dn.nervi facialis
- En.solitarius
21Postganglionic sympathetic neurons
- Arelease neurotransmtter acetylcholine
- Bhave non-myelinated axons
- Csend short fibers to the target organs
- Dhave slow-conducting fibers
- Esupply skeletal muscles
22Regarding the sympathetic division of 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 found in spinal lateral horns.
23Regarding 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.
- Eparasympathetic ganglia are close to the organs.
24The pelvic splanchnic nerves primarily carry [blank_start]preganglionic parasympathetics[blank_end] to the [blank_start]inferior hypogastric[blank_end] plexus.
- Apreganglionic parasympathetics
- Binferior hypogastric
