ANS in head

Barb Exam I

QuestionAnswer
Two major division of the ANS Sympathetic T1-L2/L3 (thoracolumbar division). Parasympathetic S2-S4 (craniosacral division).
What is the ANS controlled by Higher Centers in the hypothalamus and limbic system as well as by afferent ssny info from the periphery
anterior horn cells or CN motor nuclei project directly from the CNS to skeletal mm somatic efferent
peripheral synapse between the CNS and the effector gland or smooth muscle autonomic efferent
ssny inputs for the ANS are located where Centrally. & Peripherally.
does the ANS have afferent and efferent pathways no just efferent
enteric third division of the ANS. consist of neural plexus lying w/in the wall of the gut
Where are the preganglionic nns of the sympathetic system? Intermediolateral cell column. AKA: lateral horn
2 set of sympathetic ganglia 1. paired paravertebral ganglia. 2. paired pre vertebral ganglia .
What do the paravertebral ganglia form? Where does it run? Purpose? Sympathetic Chain. Cervical to sacral on each side of the SC. Allows sympathetic efferents, which exit only the thoracolumbar levels , to reach other parts of the body as well
location of prevertebral ganglia celiac plexus surrounding the aorta. (contain lots of ganglia)
do preganglionic sympathetics neuron or post have a longer distance to travel post ganaglionic neurons
parasympathetic preganglionic fiber must travle a _____ distance to reach there terminal ganglia located _____ or ________ effector organ Long. Within Near
parasympathetic preganglionic fiber arise where Cranial nn parasympathetic nuclei Sacral parasympathetic nuclei (located in lateral gray matter of S2-S4)
outflow of both divisions is controlled directly and indirectly by what higher centers Hypothalamus BS nuclei (nucleus solitarius) Amygdala (limbic region)
What can other ANS responses be regulated by beside higher centers? Afferent ssy info: -Signals from internal receptors (chemoreceptors, osmoreceptors, thermoreceptor and baroreceptors)
