superior cervical

In the accompanying Netter drawing, the green box indicates the lateral horn of the grey matter of the spinal cord. This region contains mainly: A. cell bodies of preganglionic parasympathetic neurons B. cell bodies of preganglionic sympathetic neurons C. cell bodies of post-ganglionic parasympathetic neurons D. cell bodies of postganglionic sympathetic neurons E. not enough information is available to answer the question

B. cell bodies of preganglionic sympathetic neurons

In the ANS, the cell bodies of the neurons whose axons innervate the effector organs are found where? A. in ganglia within the CNS B. in ganglia outside the CNS C. in nuclei within the CNS D. in the grey matter of the spinal cord E. in the cerebellum

B. in ganglia outside the CNS

The autonomic nervous system (ANS) among other things, controls ______, ________, and ______. A. walking, breathing, heart rate B. balance, speech, breathing C. heart rate, gland secretions, blood pressure D. strength of grip, blood pressure, gland secretions E. mathematical ability, breathing, heart rate

C. heart rate, gland secretions, blood pressure

In the accompanying diagram from Netter, the solid blue lines represent presynaptic parasympathetic fibers. Which parasympathetic ganglion is incorrectly matched with its neurotransmitter? READ THIS QUESTION CAREFULLY! A. celiac, serotonin B. ciliary, acetylcholine C. submandibular, norepinephrine D. otic, acetylcholine E. pterygopalatine, acetylcholine

C. submandibular, norepinephrine norepinephrine --> exciting, shouldn't be in sympathetic

In the accompanying diagram from Netter, the dashed red line represents postsynaptic (postganglionic) sympathetic fibers. The word postsynaptic means after the synapse. Where is the synapse which is referred to by the term postsynaptic? A. in the end organs (e.g. heart, intestine, trachea) B. in the chain of ganglia parallel to the vertebral column C. in the celiac, aorticorenal, superior mesenteric, and inferior mesenteric ganglia D. B & C E. in the grey matter of the brainstem

D. B & C

The majority of fibers in the white rami communicantes are: A. postganglionic parasympathetic B. postganglionic sympathetic C. preganglionic parasympathetic D. preganglionic sympathetic E. none of the above

D. preganglionic sympathetic

The sympathetic nervous system: A. is part of the parasympathetic system B. is part of the CNS C. stimulates digestion D. has neurons with their cell bodies in the grey matter of the sacral spinal cord and their axonal endplates at the effector organs E. is also called the thoracolumbar system

E. is also called the thoracolumbar system
