Sympathetic Nervous System 2022 Flashcards
How are 14 spinal cord levels able to supply sweat glands for 31 dermatomes
the sympathetic trunk is used as a pathway that lets levels T1-L2 share their preganglionic axons with somites at every level
what are they two types of visceral sensation
visceral pain
visceral afferents
what is visceral pain
pain of an internal. organ. described as dull, diffuse, or poorly localized
what is visceral afferents
visceral sensory other than pain
what stimuli would cause visceral pain
ischemia, cramping, stretching
describe the visceral pain pathways of the thorax and abdomen
visceral pain axons follow sympathetic pathways as far as the spinal nerve proper. they then pass through the dorsal root
where are the cell bodies of visceral pain pathways of the thorax and abdomen found
in the dorsal root ganglia
describe the visceral pain pathways. of the pelvis
they follow parasympathetic pathways backwards as far as the spinal nerve proper. they pass through the dorsal root
where are the cell bodies of visceral pain pathways of the pelvis found
in the dorsal root ganglia
what carries the visceral afferents for the thorax and abdomen
the vagus nerve
what carriers the visceral afferents for the pelvis
splanchnic nerves
