B Preganglionic and postganglionic sympathetic neurons are anatomically arranged in what three patterns? Pancreas A Which of the following is indicative of the relative release of catecholamines from the adrenal medulla?ġ00% acetylcholine E Which of the following descriptions of collateral ganglia is TRUE?Ĭollateral ganglia are part of the somatosensory system, located off of the afferent neuron just prior to entering the spinal cord dorsal horn.Ĭollateral ganglia are located within a chain just outside the spinal cord and are the sites of communication between sympathetic preganglionic neurons and postganglionic neurons.Ĭollateral ganglia are part of the somatic nervous system, located where the motor neuron leaves the ventral horn.Ĭollateral ganglia are located within the effector organs and are the sites of communication between parasympathetic preganglionic neurons and postganglionic neurons.Ĭollateral ganglia are in the sympathetic nervous system but distinct from the sympathetic chain, and they function as a site of communication between sympathetic preganglionic neurons and postganglionic neurons. Multiple preganglionic neurons innervate each ganglion, sending out individual postganglionic neurons B Which of the following endocrine glands is innervated by sympathetic preganglionic neurons? One preganglionic neuron sends collaterals to multiple ganglia, affecting multiple postganglionic neurons. One postganglionic neuron branches into many collaterals that affect multiple organs. One preganglionic neuron can activate only one postganglionic neuron. ![]() Several preganglionic neurons activate a single postganglionic neuron. ![]() D Which of the following contributes to the ability of the sympathetic nervous system to produce widespread responses within the body?
