ganglia Flashcards
what are special sensory ganglia
bundles of cell bodies of afferent neurons or efferent neurons
what is the soma
the cell body of the neuron
what helps transport neurotransmitters across neurons
microtubules in the axons and cell bodies
what are nerves
neurons wrapped in a bundle
where are unipolar neurons found
cerebellum to coordinate balance
what is the length of the thoraco lumbar outflow
T1-L2
what is the thoraco lumbar outflow
the sympathetic outflow of the spinal cord
what is found in the lateral grey horn of the spinal cord
cell bodies of preganglionic motor neurons of the sympathetic nervous sysem
where are chain ganglia found
on the outside of the spinal cord
what are collateral ganglia
ganglia between the spinal cord and the abdominal pelvic organ
what is the peripheral nervous system physically
axon pathways originating from the gnaglia
what are ganglion
collection of nerve cells outside of the central nervous system
what are preganglionic fibres
those that pass from the central nervous system to the ganglia
what are post ganglionic fibres
fibres going from the ganglia to the organs
what does the lower mesenteric ganglion do
supply the urinary bladder, rectum, sigmoid colon, descending colon and reproductive organs
what does the upper mesenteric ganglion supply nerves to
small intestine
what are the connections of the celiac ganglion
beginning of the small intestine, duodenum, stomach liver and pancreas
what are terminal ganglion
commonly parasympathetic ganglion situated on or around an innervated organ where the preganglionic fibres terminate
what are sensory ganglia composed of
dense myelinated nerve fibres
what are autonomic ganglia composed of
thick and thin myelinated nerve fibres
