Does parasympathetic have postganglionic axons secrete norepinephrine?
no, not all postganglionic sympathetic fibre neuron secrete NE
Is the adrenal medulla a misplaced sympathetic ganglion?
The adrenal medulla has many similarities with post-ganglionic sympathetic neurons, they release catecholamine because medullary cells are derived from the neural crest and, as such, are simply modified neurons. The adrenal gland releases epinephrine, norepinephrine and dopamine in response to neural not hormonal signals just like postganglionic neurons. The most significant different between adrenal medulla cells and true postganglionic sympathetic neurons is the absence of axons. The neurotrasmitter has become a hormone and is released into the blood.
What are the cells in animals called?
Cells. Different types of cells have different names. What type of cells are you talking about? Different parts of a body have different types of cells.
What sympathetic ganglion distributes postganglionic neuronal processes to the kidneys?
aorticorenal ganglion
Are nuclei of different cells similar in size?
No, different cells have different nuclear size.Do nuclei of cells different?
The postganglionic sympathetic fiber originates from?
The postganglionic sympathetic fiber originates from PNS within a ganglion

What has short unmyelinated postganglionic fibers?
parasynpathetic system
Which division of the autonomic nervous system is characterized by short preganglionic and long postganglionic fibers?
